Testosterone is an amazing hormone for women.
In men, testosterone is produced mainly in the testes, and in women, it's produced in the ovaries (when they're working and she's not menopausal) with a small amount made in the adrenal glands. Testosterone is a hormone found in men and less so in women. Testosterone is a sex hormone that plays an important role in the health of both men and women.
In females, half of the testosterone is produced by the ovaries and adrenal glands. A healthy level of testosterone is also protective against bone disorders such as osteoporosis and HSDD (Hypoactive Sexual Desire Disorder) or low libido in women. Even though testosterone is a male sex hormone that is important for sexual and reproductive development it does much the same in women. Female testosterone can be increased or decreased depending on the needs of the women.
The time of menopause in women is 51 years, although this can vary widely. Menopause is a normal, natural event defined as the final menstrual period and usually confirmed when a woman has missed her periods for 12 consecutive months (in the absence of other obvious causes). Menopause is the time in a woman's life when the function of the ovaries ceases and she can no longer become pregnant. Hormonal headaches typically stop when menopause is reached and hormone levels are consistently low.
Perimenopause is a term sometimes used and means "the time around menopause". Perimenopause is different for each woman but usually, the progesterone levels drop first then followed by testosterone levels. Libido drops and dryness of the eyes, mouth, and vagina occur shortly thereafter.
Muscle strength in women is due to an ample amount of female testosterone which in turn can boost female strength. Muscles can hold up for a while longer but even they start to decline and shrink in women.
The only option for replacing testosterone at the age of natural menopause or surgical menopause is a compounded cream since none is made by big pharma companies. Oral testosterone, which has long been used in women, causes a greater than 200% increase in breast cancer risk. So compounded (by a compounding pharmacy) testosterone lipodermal cream can be applied between thighs and sometimes intravaginally to end the vaginal dryness and recover the libido and end HSDD.
