Although the genitals are a key part of sex, its pleasurable sensations involve many parts of the body. Pleasurable sex heavily depends on the brain, which releases hormones that support sexual pleasure and interpret stimulation as pleasurable. One study suggests that the brain could be the most important sexual organ. Sex author found that orgasm is a heightened state of sensory awareness that can trigger a female state in the brain.
In this article, we examine the effects that sex has on the body and the brain, as well as how these effects make sex feel good. We also take a look at why sex might not feel good. In the s, sex researchers William Masters and Virginia Johnson identified four distinct phases of sexual arousal, each with unique effects on the body.
During the desire phase, the tissue in the penis, vagina, pelvis, vulva, and clitoris fill sex blood. This increases the sensitivity of nerves in these areas of the body. Muscles throughout the body begin contracting. Some people breathe more rapidly or develop flushed skin due to the increased blood flow. During the plateau stage, a person's arousal continues to intensify.
The vagina, penis, and clitoris become more sensitive. A person may experience variations in sensitivity and arousal during this period. Arousal and interest may decrease, intensify, then decrease again. For most females, clitoral stimulation is the fastest, most effective path to orgasm. For some, it is the remale path to orgasm. Males may need prolonged stimulation of the shaft or head of the penis. Most males ejaculate during orgasm, but it is possible to have an orgasm without ejaculating.
Some females also ejaculate during orgasm, though the content of this fluid remains the subject of scientific discussion. Males experience these contractions in the rectum, penis, and pelvis, while females experience them in the vagina, uterus, and rectum.
Some people experience contractions throughout the entire body. This process is different for se and females. Although most males cannot have an orgasm immediately after ejaculating, many females can. During the resolution stage, most males and many sez experience a refractory period. During female time, the person will not respond to sexual stimulation. Some researchers have proposed alternative models for resolution.
Karen Brash-McGreer and Beverly Whipple's circular female suggests that a satisfying sexual experience for a female female promptly lead to another such experience. Rosemary Basson proposes a nonlinear model of female sexual response. Her model emphasizes that females have sex for many reasons, and that their sexual response may not proceed according to predictable stages. The clitoris is, for most females, the point of origination female sexual pleasure.
It has thousands of nerve endingsmaking it highly sensitive. Sex of the clitoris extend deep into the vagina, allowing some women to get indirect clitoral stimulation through vaginal stimulation.
Learn more about the clitoris here. For men, the head of the penis is similar to the clitoris in that it is often the most sensitive area. Nerves in sexual areas of the body send specific signals to the brain, and the brain uses feale signals to create various sexual sensations. Neurotransmitters are chemical messengers that help the brain communicate with other areas of the body.
Eex neurotransmitters have a role sex sexual pleasure:. Femals is not pleasurable for everyone. In fact, some people feel pain during sex. This is much more prevalent in females. People who identify as demisexual may only experience sexual pleasure in limited contexts, such as when they feel in love with a partner. Some other factors that can affect sexual pleasure across sex genders and sexual orientations include:.
Some people, especially femalesreport that doctors dismiss sexual pain or tell them that it is all in their heads. People who do not get sensitive, responsive care from a healthcare provider should switch providers or seek sex second opinion. Sex does not have to hurt, and there is almost always a solution. A knowledgeable and compassionate provider should be committed to diagnosing and treating the issue.
Clear communication gemale a trusted partner can femae sex more pleasurable by helping the partners discuss their needs openly. A study that found a significant orgasm gap between males and females also identified strategies linked with more female — and potentially more pleasurable sex — for females. These strategies include:. Although estimates of the precise number vary, most females cannot orgasm without clitoral stimulation.
For some females, indirect stimulation from certain sexual positions, such as being on top, is enough. Others need direct, prolonged stimulation sex or separate from intercourse. This is normal and typical, and females should not feel ashamed of needing or asking for clitoral stimulation. Males may enjoy sex when it lasts longer, both because this allows pleasure to build over time and because it increases the odds that female partners will have time to orgasm.
Deep breathing may help a male delay ejaculation, as can slowing down when the sensations become too intense. For people who find it difficult to get or maintain an erection, exercise may increase blood flowimproving an erection and sexual performance. Erectile dysfunction medications such as sildenafil Viagra may also be helpful. People may find that using a sexual lubricant decreases friction, improving sex.
Lubricants female available to buy in many stores and online. Pelvic floor exercises strengthen the muscles that play a role in orgasm, potentially helping both males and females have stronger orgasms and better control over the timing of orgasm. To exercise the pelvic floor, try tightening the muscles aex stop the stream of urine. Some female practice this by stopping and starting again when using femaale bathroom. Gradually build up to holding the position for femake seconds or longer, and repeat it throughout the day.

There is no "right" way to feel about sex and no correct way to have sex. People can experience sexual pleasure from a wide range of positions, types of sex, and sexual fantasies.
Open communication, self-acceptance, and a willingness to seek help when something does not work can promote sexual pleasure and reduce stigma.

The female reproductive system is made female of the internal and external sex organs that function in reproduction of new offspring. In the human the xex reproductive system is immature at birth and develops to female at puberty to be able to produce gametesand to carry a foetus to full term. The internal sex organs are the uterusFallopian tubesand ovaries. The uterus or womb accommodates the embryo which develops into xex foetus.
The uterus also produces vaginal and uterine secretions which help the transit of sperm to the Fallopian tubes. The ovaries produce the ova egg cells. The external sex organs are also known as the genitals and these are the organs of the vulva including the labia fwmale, clitorisand vaginal opening. The vagina is connected to the uterus at the cervix.
Female certain intervalsthe ovaries release an ovumwhich passes through feemale Fallopian tube into the uterus. If, in this transit, it meets with sperm, a single sperm 1-cell can enter and merge with the egg or ovum 1-cellfertilizing it into a zygote 1-cell. Fertilization usually occurs in the Fallopian tubes and marks the beginning of embryogenesis. Sexx zygote will then divide over enough generations of cells to form a blastocyst female, which implants itself in the wall of the uterus.
This begins the period of gestation and the embryo will continue to develop until full-term. When the foetus has developed enough to survive outside the uterusthe cervix dilates and contractions of the uterus propel the newborn through the birth sed the vagina. The corresponding equivalent fwmale males is the male reproductive system. The vulva consists of all of the external parts and tissues and includes the mons pubispudendal cleftlabia majora femaoe, labia minoraBartholin's glandsclitorisand vaginal opening.
The vagina is a fibromuscular made up of fibrous and muscular tissue canal leading from the outside of the body to the cervix of the uterus or womb. It is also referred to as the birth canal in the context of pregnancy.
The vagina accommodates the male penis during sexual intercourse. Semen containing spermatozoa is ejaculated from the male at orgasminto the vagina potentially enabling fertilization of the egg cell ovum to take place. The cervix is the neck of the uterus, the lower, narrow portion where it joins with the upper part of the vagina. It is cylindrical or conical in shape and protrudes through the upper anterior vaginal wall. Approximately half its length is visible, the remainder lies above the vagina beyond view.
The vagina has a thick layer outside and it is the opening femmale the foetus emerges femwle delivery. The uterus or womb is the major female reproductive organ. The uterus provides mechanical protection, nutritional support, and waste removal for the developing embryo weeks 1 to 8 and fetus from sex 9 until the delivery. In addition, contractions in the muscular wall of the uterus are important in pushing out the fetus at the time of birth. The uterus contains three suspensory ligaments that help stabilize the position ffemale the uterus and limits its range of movement.
The uterosacral ligaments keep the body from moving inferiorly and anteriorly. The round ligaments restrict posterior movement of the uterus. The cardinal ligaments also prevent the inferior movement of the uterus.
The uterus is gemale pear-shaped muscular organ. Its major function is to accept a fertilized ovum which becomes implanted into the endometriumand derives nourishment from blood vessels which develop exclusively for this purpose.
The fertilized ovum becomes an embryodevelops into a fetus and gestates sxe childbirth. If the egg does female femald in the wall of the uterus, a female begins menstruation. The Fallopian tubes are two tubes leading from the ovaries into the uterus. On maturity of an ovum, the follicle and the ovary's wall rupture, allowing the ovum to escape and enter the Fallopian tube. There it travels toward the uterus, pushed along by movements femlae cilia on the inner lining of the tubes.
Fejale trip takes hours or days. If the ovum is fertilized while in the Fallopian tube, then it normally implants in the endometrium when it reaches the uterus, which signals the beginning of pregnancy. The ovaries are small, paired organs femle near the lateral walls of the pelvic cavity. These organs female responsible for the production of the egg cells ova and the secretion of hormones. The process by which sex egg cell ovum is released is called ovulation.
The speed of ovulation is periodic se impacts directly to the length of a menstrual cycle. After ovulation, the egg cell is captured by the Fallopian tube, after traveling down the Fallopian tube to the uterus, occasionally being fertilized on its sex by an incoming sperm.
During fertilization the egg cell plays a female it releases certain molecules that are essential aex guiding the sperm and allows the surface of the egg to attach to the sperm's surface. The egg can then absorb the sperm and fertilization can then femzle. The reproductive tract or genital female is femle lumen that starts as a single pathway through the vagina, splitting up into two lumens in the uterus, both of which continue through the Fallopian tubes, and ending at the distal ostia that open into the abdominal cavity.
In the absence of fertilization, the ovum will eventually traverse the entire reproductive tract from the fallopian tube until exiting the vagina through menstruation. The reproductive tract can be used for various transluminal procedures such as fertiloscopyintrauterine inseminationand transluminal sterilization. Chromosome characteristics frmale the genetic sex of a fetus at conception.
This is specifically based on the 23rd pair of chromosomes that is inherited. Since the mother's egg fekale an X chromosome and the father's sperm contains either an X or Y chromosomeit is the male who determines the fetus's sex.
If the fetus inherits the X chromosome from the father, the fetus will be a female. The clitoris femalr the remnants of the Wolffian duct. On the other hand, if the fetus inherits the Y chromosome from the father, the fetus will be a male. Vaginitis is inflammation of the vagina and largely caused by an infection.
It femalf the most common gynaecological condition presented. It is difficult to determine any one organism most responsible for vaginitis because it varies from range of age, sexual activity, and method of microbial identification.
Vaginitis is not necessarily caused by a sexually transmitted infection as there are many infectious agents that make use of the close proximity to mucous membranes and secretions. Vaginitis is usually diagnosed based on the presence of vaginal discharge, which can have a certain color, odor, femaale quality. This is a vaginal infection in women. It differs from vaginitis in that there is no inflammation. Bacterial vaginosis is polymicrobial, consisting of many bacteria species.
The diagnosis for bacterial vaginosis is made if three of the following four criteria are present: 1 Homogenous, femalee discharge, 2 a pH of 4. It has been associated with an increased risk of other genital tract infections such as endometritis. Yeast infections are caused by an overgrowth of fungus in the vagina known as Candida. Yeast infections are usually caused by an imbalance of the pH in the vagina, which is usually acidic.
Other factors such as pregnancy, aex, weakened immune systems, tight fitting clothing, or douching can also be a cause. Symptoms of yeast infections include itching, burning, irritation, and a white cottage-cheese-like discharge from the vagina. Women have also reported that sex experience painful intercourse and urination as well.
Taking a sample of the vaginal secretions and placing them under a microscope for evidence of yeast can diagnose a yeast infection. Treatment varies from creams that can be applied in or around the vaginal area to oral tablets that stop the growth of fungus. There are many practices of mutilating female genitalia in different cultures. The most common two types of genital mutilation practiced are clitoridectomythe circumcision of the clitoris and the excision of the prepuce the skin around the clitoris.
They can all involve a range of adverse fdmale consequences such as bleedingirreparable tissue damage, and sepsis which can sometimes prove fatal. Genitoplasty refers to surgery that is carried out to repair damaged sex organs particularly following cancer and its treatment. There are also elective surgical procedures which change the appearance of the external genitals.
The International Federation of Gynaecology femald Obstetrics was founded in to promote the well-being of women particularly in raising the standards of gynaecological practice and care.
As of there were countries involved. Reproductive rights are legal rights related to reproduction and reproductive health.
Women have the right to control matters involving their sexuality including their sexual and reproductive health. Violation of these rights include forced pregnancy, forced sterilization, forced abortion and genital mutilation. Female genital mutilation is the complete or partial femalf of a female's external genitals. It is sex in the Hippocratic writings sxe both males and females contribute their seed to conception; otherwise, children would not resemble either or both of their parents.
Four-hundred years later, Galen "identified" the source of 'female semen' as the ovaries in female reproductive organs. Sex Wikipedia, the free encyclopedia.

Reduced sex drive
After 4 weeks, those who took the extract reported an improvement in their sexual desire, arousal, and satisfaction. The downside? It was a pretty small study that involved only 60 participants. Tribulus terrestris may be a bit harder to find than some of the other herbs discussed in this article, so your best bet is to purchase online. It comes in the form of:. A popular and expensive spice, saffron is often recommended as an aphrodisiac — and early research backs it up. In one study , women taking antidepressants saw a significant improvement in sexual arousal after taking saffron for 4 weeks.
However, while this study found an improvement in sexual arousal, it did not see an improvement in sexual desire. You can find saffron threads in specialty grocery stores or spice shops.
Red wine is a widely recommended aphrodisiac. In addition to its other potential benefits , red wine may also improve sexual function, according to a study. Plus, other studies suggest that consuming too much alcohol may have the reverse effect on libido, so moderation is key.
Believe it or not, apples may have a positive effect on female sex drive. One study found that women who consumed an apple a day reported a better quality sex life. While this sounds promising, this study only suggests a correlation between apple consumption and sexual health. Plus, there are no other major studies on whether apples may increase libido.
Fenugreek is an herb used both in cooking and as a supplement. Some research suggests it may help boost libido. A study concluded that fenugreek may be an effective treatment to increase female sex drive. However, most of the current research on fenugreek covers male sexual health. You can find fenugreek in grocery stores, spice shops, and online. While not backed by any evidence, these foods and herbs have historically been used to boost libido.
Some people swear by them. Plus, you likely already have many of them in your kitchen, making them easy to try. Chocolate is a commonly recommended aphrodisiac. The original Casanova is said to have started each day by eating 50 raw oysters. Males and females alike have reported increased sex drive after eating them. Capsaicin, the active component of chili peppers , offers several health benefits, including improved sex drive. In fact, a systematic review concluded the opposite.
After looking at the data from multiple studies, researchers listed decreased libido as a potential side effect of saw palmetto usage. However, little is known about saw palmetto use by women. Another commonly recommend aphrodisiac, figs are a rich source of vitamins and minerals. But the jury is out on their effect on libido. However, bananas are a great source of potassium, which aids in testosterone synthesis.
While testosterone is typically seen as a male hormone, females also have testosterone, and low testosterone can negatively affect sex drive.
However, both potatoes and sweet potatoes are full of potassium, meaning they offer the same health benefits as bananas. Despite their popularity, yohimbine or yohimbe supplements are potentially harmful. Spanish fly is another aphrodisiac that should be avoided due to its potentially dangerous side effects. Common side effects of Spanish fly include difficulty swallowing, nausea, vomiting blood, painful urination, and blood in the urine. While mad honey has historically been used as an aphrodisiac, side effects can include dizziness, nausea, vomiting, convulsions, headache, palpitations, and more.
Looking for other ways to boost your libido? The vagina is a muscular, hollow tube that extends from the vaginal opening to the uterus. Because it has muscular walls, the vagina can expand and contract. This ability to become wider or narrower allows the vagina to accommodate something as slim as a tampon and as wide as a baby.
The vagina's muscular walls are lined with mucous membranes, which keep it protected and moist. A very thin piece of skin-like tissue called the hymen partly covers the opening of the vagina. Hymens are often different from female to female. Most women find their hymens have stretched or torn after their first sexual experience, and the hymen may bleed a little this usually causes little, if any, pain.
Some women who have had sex don't have much of a change in their hymens, though. And some women's hymens have already stretched even before they have sex. The vagina connects with the uterus , or womb, at the cervix which means neck. The cervix has strong, thick walls. The opening of the cervix is very small no wider than a straw , which is why a tampon can never get lost inside a girl's body. During childbirth, the cervix can expand to allow a baby to pass.
The uterus is shaped like an upside-down pear, with a thick lining and muscular walls — in fact, the uterus contains some of the strongest muscles in the female body.
These muscles are able to expand and contract to accommodate a growing fetus and then help push the baby out during labor. When a woman isn't pregnant, the uterus is only about 3 inches 7. At the upper corners of the uterus, the fallopian tubes connect the uterus to the ovaries. The ovaries are two oval-shaped organs that lie to the upper right and left of the uterus.
They produce, store, and release eggs into the fallopian tubes in the process called ovulation pronounced: av-yoo-LAY-shun. There are two fallopian pronounced: fuh-LO-pee-un tubes, each attached to a side of the uterus. Within each tube is a tiny passageway no wider than a sewing needle.
At the other end of each fallopian tube is a fringed area that looks like a funnel. This fringed area wraps around the ovary but doesn't completely attach to it. When an egg pops out of an ovary, it enters the fallopian tube. Once the egg is in the fallopian tube, tiny hairs in the tube's lining help push it down the narrow passageway toward the uterus. The ovaries pronounced: OH-vuh-reez are also part of the endocrine system because they produce female sex hormones such as estrogen pronounced: ESS-truh-jun and progesterone pronounced: pro-JESS-tuh-rone.
Most people think of the gonads as the male testicles. But both sexes have gonads: In females the gonads are the ovaries, which make female gametes eggs. The male gonads make male gametes sperm. When a baby girl is born, her ovaries contain hundreds of thousands of eggs, which remain inactive until puberty begins. At puberty, the pituitary gland in the central part of the brain starts making hormones that stimulate the ovaries to make female sex hormones, including estrogen.
The secretion of these hormones causes a girl to develop into a sexually mature woman. Toward the end of puberty, girls begin to release eggs as part of a monthly period called the menstrual cycle. The ova are defined as the larger gametes in a heterogamous reproduction system , while the smaller, usually motile gamete, the spermatozoon , is produced by the male. A female individual cannot reproduce sexually without access to the gametes of a male, and vice versa.
Some organisms can also reproduce by themselves in a process known as asexual reproduction. An example of asexual reproduction that some female species can perform is parthenogenesis. Other than the defining difference in the type of gamete produced, differences between males and females in one lineage cannot always be predicted by differences in another. The concept is not limited to animals; egg cells are produced by chytrids , diatoms , water moulds and land plants , among others.
In land plants, female and male designate not only the egg- and sperm-producing organisms and structures, but also the structures of the sporophytes that give rise to male and female plants. It is not etymologically related to the word male , but in the late 14th century the spelling was altered in English to parallel the spelling of male.
A distinguishing characteristic of the class Mammalia is the presence of mammary glands. The mammary glands are modified sweat glands that produce milk, which is used to feed the young for some time after birth. Only mammals produce milk. Mammary glands are most obvious in humans , as the female human body stores large amounts of fatty tissue near the nipples, resulting in prominent breasts. Mammary glands are present in all mammals, although they are seldom used by the males of the species.
Most mammalian females have two copies of the X chromosome as opposed to the male which carries only one X and one smaller Y chromosome but some mammals, such as the platypus , have different combinations. To compensate for the difference in size, one of the female's X chromosomes is randomly inactivated in each cell of placental mammals while the paternally derived X is inactivated in marsupials. In birds and some reptiles, by contrast, it is the female which is heterozygous and carries a Z and a W chromosome whilst the male carries two Z chromosomes.
However, these conditions frequently result in sterility. Mammalian females bear live young with the rare exception of monotremes , which lay eggs. Some non-mammalian species, such as guppies , have analogous reproductive structures; and some other non-mammals, such as sharks , whose eggs hatch inside their bodies, also have the appearance of bearing live young.
According to Schott,  the most established view is that the male and female symbols are derived from contractions in Greek script of the Greek names of these planets, namely Thouros Mars and Phosphoros Venus. These derivations have been traced by Renkama  who illustrated how Greek letters can be transformed into the graphic male and female symbols still recognised today. These abbreviations were contracted into the modern symbols. The sex of a particular organism may be determined by a number of factors.
These may be genetic or environmental, or may naturally change during the course of an organism's life.
Barring rare medical conditions, most female femlaeincluding female humanshave two Femals chromosomes. Female characteristics vary between different species with some species containing more well defined female characteristics, such as the presence of pronounced mammary glands.
There is no single femalee mechanism behind sex differences in different species and the existence of female sexes seems to have evolved multiple times independently in different evolutionary lineages. The word female comes from female Latin femellathe diminutive form of feminameaning " woman ". The sex are defined as the larger gametes in a heterogamous reproduction systemwhile the smaller, usually motile gamete, the spermatozoonis produced by the male. A female individual cannot reproduce sexually without access to the gametes of a male, and vice versa.
Some organisms can also reproduce by themselves in a process known as asexual reproduction. An example of asexual reproduction that some female species can perform is parthenogenesis. Other than the defining difference in the type of female produced, differences between males and females in one lineage cannot always be predicted by differences in another.

In land plants, female and male designate sex only the remale and sperm-producing organisms and structures, but also the female of the sporophytes that give rise to male and female plants.

Although most wex with male and female sexes have individuals that are either male or female, hermaphroditic animals have both male and female reproductive organs. The sex of most mammals, including humans, is genetically determined by dex XY sex-determination system where males have X and Sex as opposed to X and Demale sex chromosomes.
During reproductionsxe male contributes either an Sex sperm or a Y sperm, while the female always contributes an X egg. A Y sperm and an X egg produce a male, while an X sperm and an X egg produce a female.
The ZW sex-determination systemwhere males have ZZ as opposed to ZW sex chromosomes, is found in birds, reptiles and some insects and other femape. Members of Hymenopterasuch as ants and bees, are determined by haplodiploidywhere most males are haploid and females and some sterile males are diploid.
The young of some species develop into one sex or the other depending on local environmental conditions, e. Other species such as the goby can transform, as adults, from one sex to the other in response to local reproductive conditions such as a brief shortage female males.
