These hormones fluctuate during the menstrual cycle. This could lead one to believe that women are more interested in sex at the beginning of their cycle. However, this is not true for all women. That said, recent research suggests that testosterone might not be as influential as once thought. Researchers have found that ovulating women may display certain behaviors in order to attract men, even if they are unaware of it.
With surgical removal of the ovaries there is an immediate and substantial drop in circulating androgens. Most controlled studies of testosterone replacement in hypogonadal men have used a period of withdrawal as a baseline, followed by the administration of testosterone and placebo, using a double-blind cross-over design for review see Bancroft Dorsally, neurons run to the PVN of the hypothalamus and then on to the brainstem to structures involved in the autonomic nervous system Herbert The l.

Hormones are natural substances produced in the body. They help to relay messages between cells and organs and affect many bodily functions. Keep reading to learn more about the female sex hormones, how they fluctuate throughout your life, and signs of a hormonal imbalance.
The two main female sex hormones are estrogen and progesterone. Although testosterone is considered a male hormone, females also produce and need a small amount of this, too. Estrogen is the major female hormone. During pregnancy, the placenta also makes estrogen. Estrogen levels can be determined by a blood test.
The ovaries produce the female sex hormone progesterone after ovulation. During pregnancy, the placenta also produces some. Progesterone levels can be determined by a blood test. Small amounts of testosterone come from the adrenal glands and ovaries. This hormone plays a role in several body functions, including:. A blood test can determine your testosterone level. Female sex hormones are integral to many body functions.
But your hormonal needs change a great deal as you leave childhood and enter puberty. They also change dramatically if you become pregnant, give birth, or breastfeed.
And they continue to change as you near menopause. Everyone is different, but most females enter puberty between the ages of 8 and And it all happens because of hormones. Production increases at puberty, which in turn stimulates the sex hormones — especially estrogen.
The first menstrual period menarche happens about two to three years after the breasts begin to develop. Every month, the uterus thickens in preparation for a fertilized egg. This prompts your uterus to shed its lining.
The day you start to bleed is day 1 of your cycle, or the follicular phase. The pituitary gland starts to produce a little more FSH. This spurs growth of follicles in your ovaries. Within each follicle is an egg. As sex hormone levels drop, only a single, dominant follicle will continue to grow. As this follicle produces more estrogen, the other follicles break down. Higher levels of estrogen stimulate an LH surge. This phase lasts about two weeks. Next comes the ovulatory phase.
LH causes the follicle to rupture and release the egg. This phase lasts about 16 to 32 hours. Fertilization can only occur for about 12 hours after the egg has left the ovary. The luteal phase starts after ovulation. The ruptured follicle closes and the production of progesterone increases. This gets the uterus ready to receive a fertilized egg. The entire menstrual cycle lasts around 25 to 36 days. Bleeding lasts between 3 and 7 days.
But this, too, varies quite a bit. Your cycle may be quite irregular for the first few years. It can also vary at different times of your life or when you use hormonal contraceptives. Estrogen, progesterone, and testosterone all play a role in female sexual desire — also called libido — and sexual functioning.
Due to hormonal fluctuations, females are generally at the peak of sexual desire just before ovulation. Your libido may also fluctuate less after menopause. Undergoing surgery to remove your adrenal glands or ovaries cuts down on testosterone production, which can cause a drop in your libido. During the luteal phase of your cycle, the rise in progesterone prepares your uterus to receive a fertilized egg.
The uterine walls get thick and fill with nutrients and other fluids to sustain an embryo. Progesterone thickens the cervix to protect the uterus from bacteria and sperm. Estrogen levels are also higher, contributing to the thickening of the lining of the uterus. Both hormones help milk ducts in the breasts to dilate. As soon as conception takes place, you start to produce human chorionic gonadotropin hormone hCG.
This is the hormone that shows up in your urine and is used to test for pregnancy. It also boosts the production of estrogen and progesterone, preventing menstruation and helping to sustain the pregnancy. Human placental lactogen hPL is a hormone made by the placenta. In addition to providing nutrients for the baby, it helps stimulate milk glands for breastfeeding. Levels of another hormone called relaxin also rise during pregnancy.
Relaxin aids in the implantation and growth of the placenta and helps stop contractions from happening too soon. As labor begins, this hormone helps relax ligaments in the pelvis. Once pregnancy ends, hormone levels start to fall immediately. They eventually reach pre-pregnancy levels. A sudden, significant drop in estrogen and progesterone may be a contributing factor in the development of postpartum depression. Breastfeeding lowers estrogen levels and can prevent ovulation.
During perimenopause — the period leading up to menopause — hormone production in your ovaries slows down. Estrogen levels begin to fluctuate while progesterone levels start a steady decline. As your hormone levels drop, your vagina may become less lubricated.
Some people experience a decrease in their libido and their menstrual cycle becomes irregular. By this time, both estrogen and progesterone are holding steady at low levels. This typically happens around age Decreased hormones after menopause may increase your risk of conditions such as thinning bones osteoporosis and cardiovascular disease. Your hormones will naturally fluctuate throughout your lifetime.

Hormones That Affect Sexual Desire - Our Bodies Ourselves
It is commonly equated with genital response; thus the man who has an erection is said to be sexually aroused. As used in this paper, the concept of sexual arousal involves more than genital response Bancroft a , covering a state motivated towards the experience of sexual pleasure and possibly orgasm, and involving i information processing of relevant stimuli, ii arousal in a general sense, iii incentive motivation and iv genital response. In this paper, sexual interest is conceptualized as an aspect of sexual arousal, when all four components may be involved to some extent, but where at least sexual information processing e.
Orgasm needs to be considered, both as a goal of the incentive motivation, and as a process associated, at least in males, with a temporary suspension or inhibition of sexual arousability. This paper will review the role of hormones in influencing sexual arousal, sexual arousability, orgasm and the post-orgasm inhibition of arousability. Its focus will be on the human experience, but reference to the animal literature will be made when helpful in understanding the human condition. Most controlled studies of testosterone replacement in hypogonadal men have used a period of withdrawal as a baseline, followed by the administration of testosterone and placebo, using a double-blind cross-over design for review see Bancroft Such studies consistently show a reduction in the level of sexual interest during testosterone withdrawal, usually evident within 3 to 4 weeks, consistent with testosterone being necessary for normal levels of sexual interest and arousability.
If testosterone withdrawal lasts long enough, seminal emission will eventually be impaired. Typically, in male studies of this kind, placebo has only a modest effect, but testosterone replacement restores sexual interest and arousability. Effects on sexual activity with a partner are less consistent, partly because they depend on partner and relationship characteristics.
Frequency of masturbation tends to follow the level of sexual interest, although cultural factors may influence this pattern of sexual expression Anderson et al. Psychophysiological studies have been used to assess the effects of testosterone withdrawal and replacement on genital response erection to sexual stimuli. Early studies were based on the maximum change in penile circumference as a measure of erectile response; they found little difference between hypogonadal men with and without testosterone replacement.
More recently, such assessment has also included penile rigidity as well as duration of penile response. This showed significantly more rigid and longer duration erectile responses with testosterone replacement. With testosterone replacement, the response would not only show greater rigidity, but would also last beyond the sexual stimulus Carani et al.
Nocturnal penile tumescence NPT , the occurrence of spontaneous erections during rapid eye movement REM sleep, is relevant. NPT is clearly impaired in hypogonadal men, and restored to normal with testosterone replacement.
The l. Carani et al. Intramuscular testosterone enanthate had no effect on sleep parameters, and did not affect frequency, degree or duration of NPT, when assessed as penile circumference, but did increase, modestly but significantly, penile rigidity during NPT. Testosterone manipulation in eugonadal men has produced results consistent with the earlier hypogonadal studies.
Bagatell et al. This lowered sexual interest and associated sexual activity. An additional feature was the administration of varying doses of exogenous testosterone or placebo during the NalGlu administration.
This suggested that the plasma level of testosterone needed to avoid the sexual effects of testosterone withdrawal was substantially lower than the pre-treatment baseline level. This is consistent with most men having more circulating testosterone than they need for the maintenance of normal sexual function. The exploration of testosterone as a method of male contraception has led to further studies of the effects of increasing circulating testosterone above a normal baseline by means of exogenous testosterone administration.
Anderson et al. Buena et al. They first suppressed testicular function with a GnRH agonist Lupron , followed by exogenous testosterone administration in either high or low dosage, to produce testosterone levels that were either at the high end or low end of the normal range.
Whereas the importance of testosterone in sexual differentiation, both in early development and around puberty, is beyond dispute, the impact of testosterone on the emergence of sexual arousability is less clear. Udry and colleagues carried out two studies in teenage boys in which testosterone levels were related to various aspects of sexuality.
In the first Udry et al. In the second Halpern et al. One possible explanation for this apparent contradiction is that the impact of testosterone on sexual arousability and hence behaviour has to go through stages of development, which may involve changes in receptor numbers or sensitivity, a process which will also be influenced by individual differences in receptor sensitivity. Gooren , in a study of hypogonadal teenage males, found that boys with primary hypogonadism showed less response to testosterone replacement than boys with secondary hypogonadism.
Other studies comparing hyper-gonadotrophic and hypogonadotrophic hypogonadism have not shown such clear differences, but have all involved males well beyond the age of normal puberty for review see Bancroft Schiavi et al. The relatively predictable effects of testosterone withdrawal and replacement in younger adult men gives way to a more complex, or at least less well-understood picture in older men.
A number of age-related changes may be relevant: altered negative feedback of testosterone and hence less increase in luteinizing hormone LH with falling testosterone levels, increased sex hormone binding globulin SHBG and hence relatively reduced free testosterone and the likelihood of an age-related decline in testosterone receptor sensitivity.
This suggested an age-related decline in testosterone-dependent central arousability i. It is noteworthy that, as yet, there has been no adequate placebo-controlled evaluation of the effects of testosterone replacement on sexuality in older men Institute of Medicine The limited evidence of the effectiveness of testosterone in treating ED is inconsistent.
In studies of men showing some degree of hypogonadism in association with ED, Carani et al. So far it has been difficult to predict which cases of ED are likely to benefit from testosterone, although low baseline levels of testosterone certainly increase the likelihood. The evidence is fairly clear that in men who have gone through normal puberty and who have not yet been affected by aging, testosterone plays an important role in their sexual interest and associated sexual arousability.
The evidence points mainly to the effects of testosterone on central arousal mechanisms; the peripheral effects of testosterone in the human male, relevant to sexual arousal, are as yet unclear. It is also apparent that, in adult eugonadal men, the levels of testosterone in the circulation are substantially higher than required to maintain sexual arousability, suggesting that other effects of testosterone, most probably in the periphery, require higher levels than are needed in the central nervous system CNS.
The role of testosterone in the emerging sexual arousability of the peri-pubertal male is not well understood. In the older male, the picture is complicated by various aging effects, including altered hypothalamo—pituitary feedback, increased testosterone binding and reduced receptor sensitivity. In the female, in comparison with the male, we find inconsistent and often contradictory evidence.
This is in spite of the fact that we have many more studies in women, usually involving larger samples, than are found in the male literature. This may result from the greater complexity of the reproductive endocrine system in women, who experience menstrual cycles, pregnancy and lactation and a clearly identifiable menopause.
Increasing levels of testosterone occur in the development of girls as they approach and go through puberty. However, the changes are much less substantial than in the male. Testosterone starts at a lower level in the infant girl, and effectively doubles through pubertal maturation, compared with an fold increase in testosterone for boys. The most substantial evidence of the relationship between testosterone and emerging sexual arousability in females comes again from Udry et al.
As with their studies on adolescent boys, they found discrepant results between their cross-sectional study of eighth to tenth grade girls approximately 13—15 years of age , where they found a relation between testosterone levels and measures of sexual interest and masturbation, but not with the likelihood of having experienced sexual intercourse, and their longitudinal study of girls post-menarche where the reverse relations to testosterone were found Halpern et al.
Similar explanations as discussed for their male studies could apply here, but in addition there is a crucial methodological issue of timing of blood sampling for testosterone in relation to the ovarian cycle for a fuller discussion of these issues see Bancroft There is a lack of evidence of testosterone levels during the early cycles of post-menarcheal adolescents, which tend to be irregular and not predictably ovulatory. However, once a woman settles into a pattern of regular ovulatory cycles, testosterone levels typically rise during the follicular phase and are at a maximum approximately for the middle third of the cycle, declining during the final third to reach a nadir during the first few days of the next follicular phase.
Given this pattern, if testosterone is important for sexual arousability in women, we should expect to find related temporal patterns of arousability through the cycle. However, the mid-cycle rise in testosterone is associated with other hormonal changes, and hence correlational studies may not discriminate between direct effects of mid-cycle testosterone levels, and the effects of other mid-cycle changes, such as the rise in oestradiol.
In the substantial literature on the pattern of sexual interest and behaviour through the menstrual cycle there are many inconsistencies, and Hedricks has discussed various methodological explanations for them.
There is a relatively consistent finding that sexual activity is lowest during the menstrual phase. However, this does not necessarily mean that sexual arousability is at its lowest at that stage; there are a number of other non-hormonal explanations for the drop in sexual activity during menstruation.
There is also a tendency across studies for indices of sexual interest to be highest during the follicular phase or around ovulation, though with considerable individual variability in this respect. This mid- to late-follicular pattern is compatible with an effect of the rising testosterone during the follicular phase, although one might have expected a continuation of this testosterone effect into the first part of the luteal phase.
Clearly, other hormonal explanations have to be considered. A much more limited literature looks at the correlation between testosterone level and sexuality through the cycle, and it is very inconsistent for review see Bancroft In part, there may be methodological reasons for this, especially variability in the aspects of sexuality measured.
Only one study addresses the timing of the effects of an increase in testosterone on sexual arousal. Eight healthy women with normal testosterone levels, given sublingual doses of testosterone in a placebo-controlled experiment, showed effects of increased testosterone on genital response to erotic stimuli occurring 3—4 h after the peak increase in plasma testosterone Tuiten et al.
There is consistent evidence that combined low-dose oral contraceptives OCs lower free testosterone e. Bancroft et al. Two principle mechanisms are involved: the mid-cycle rise in testosterone is blocked by suppression of ovulation and the associated pattern of gonadal steroid change and the combined OC increases SHBG levels and hence reduces the free testosterone available.
Given this predictable hormonal effect, what happens to sexual arousability in combined OC users? Graham et al. In a subsequent study of women starting on OCs, where a pre-OC baseline was established, negative effects on sexual interest and mood were the best predictors of discontinuation of the OC Sanders et al. In both of these studies, lowered testosterone levels could be the explanation.
As yet, however, we have no direct evidence of the relation between testosterone levels and sexual interest. Other explanations for these adverse sexual effects need to be considered e.
But if lowered free testosterone is the explanation this illustrates once again that such reduction is only relevant in a proportion of women.
Cyproterone acetate CPA is an anti-androgen with both negative feedback and direct androgen receptor antagonism, and which has been used for the treatment of androgen-dependent conditions such as acne and hirsutism in women. Alder et al. Not surprisingly, given the effects of lactation on ovarian function, bottle feeders had higher testosterone and androstenedione levels than the breast-feeding mothers. Of more relevance, five of the breast feeders reported reduced sexual interest, and their testosterone and androstenedione levels were consistently and significantly lower than the breast feeders who reported no reduction in sexual interest.
This finding needs to be replicated. Adrenal androgens have been shown, in a number of studies Crilly et al. Ovarian androgens start to decline a few years before the menopause, probably due to a reduction in the mid-cycle rise of testosterone Roger et al.
A crucial change in the function of the interstitial cells of the ovary from pre- to post-menopause complicates the picture. Whereas in pre-menopausal women, gonadotrophic stimulation of the interstitial cells is regulated by the negative feedback of ovarian steroids, the rise in LH that accompanies the menopausal transition, resulting from the reduction in oestrogen-induced negative feedback, may stimulate the interstitial cells to produce testosterone and androstenedione, sometimes excessively.
A number of behavioural studies have reported a decline in sexual interest in women as they age see Bancroft , Bancroft et al.
Studies have varied in the extent to which the menopause per se contributes to this decline, although there is consistent evidence of an increase in vaginal dryness related to the change in oestradiol levels Dennerstein et al. Do testosterone levels correlate with measures of sexual interest or activity as women get older? In their longitudinal study of women going through the menopausal transition, assessed over a 9-year period, with an average starting age of 48 years, Dennerstein et al.
However, in none of these studies was there any assessment of the pre-menopausal testosterone decline.
