Hormonal Therapy

Female
Hormonal Therapies

Hormones or hormone-blocking therapies may be prescribed in an effort to treat infertility, cancer, and some forms of sexual dysfunction. Following is a basic explanation of female hormonal therapies.

Dr. Pinson and his staff are highly knowledgeable about these options, and look forward to answering any questions you may have.

Androgens

Androgens are naturally synthesized by the ovary, the adrenal gland, and from androgen precursors in peripheral organs. Androgen synthesis occurs in only one direction in the body, and while all these androgen and androgen precursor hormones are likely important for tissue structure and function, only four of the seven may be clinically measured: dehydroepiandrosterone (DHEA), androstenedione, testosterone, and dihydrotestosterone (DHT).
Dehydroepiandrosterone, the first or precursor androgen, is converted by an enzyme into androstenedione, which is then converted by a different enzyme into testosterone, which is then converted by a different enzyme to dihydrotestosterone. Women with low dehydroepiandrosterone blood levels can raise that level and the rest of the androgen levels with dehydroepiandrosterone treatment. In contrast, women with low testosterone blood levels raise only the testosterone and dihydrotestosterone levels with testosterone therapy, as you can’t convert “backwards” into the early part of the synthetic cascade. It should be noted that both dehydroepiandrosterone and testosterone use can raise estradiol values in women. This action is due to testosterone converting to estradiol by the enzyme aromatase.

Androgens and androgen precursors have a profound effect on many physiological functions in women, including: stimulation of sexual desire, interest, thoughts, and fantasies; regulation of genital (vaginal and clitoral) blood flow; amount and quality of vaginal lubrication; structural and functional integrity of the clitoris, prepuce, vaginal muscularis (smooth muscle layer), G-spot, and minor vestibular glands; stimulation of bone growth; increase in muscle mass; maintenance of energy and well-being; maintenance of lean body composition; control of oil gland activity in skin; and regulation of body hair growth. Although testosterone appears to be a vital component of women’s sexual health and is an important factor in women’s overall health, women with low testosterone can still have a satisfactory sex life.

DHEA

Dehydroepiandrosterone, or DHEA, is considered an “off-label” treatment, as it is not approved specifically for use in women with sexual health concerns. The bioidentical form of DHEA is recommended, but many brands actually have limited amounts of active medication. Blood tests measuring dehydroepiandrosterone-sulfate, usually at six-week to three-month intervals, should be repeated until the appropriate blood level is stable.

Testosterone

Testosterone is the most common “off-label” androgen prescribed for treatment of sexual dysfunction in women. The individual dose for women with sexual health problems is usually 10 percent of a man’s daily dose, but blood tests of “unbound” testosterone, usually at three-month intervals, must be repeated to establish the appropriate dose for each woman with sexual health concerns. Reports documenting facilitation of the sexual response in women by testosterone were published as early as 1938.
