Newswise — Hormonal changes induced by oral contraceptives (OC) are not immediately reversible after discontinuation of use, according to new research issued today at the American Association of Clinical Endocrinologists (AACE) Fourteenth Annual Meeting and Clinical Congress.

Despite the benefits of OC, their use has been associated with sexual dysfunction and androgen insufficiency. OC are known to decrease serum testosterone levels by decreasing ovarian production of testosterone and by increasing production of sex hormone-binding globulin (SHBG) from the liver. It has been assumed that these changes are reversible after discontinuation of OC use.

In the study of 102 pre-menopausal women with female sexual dysfunction, SHBG values in the OC group were seven times higher than those in the never-user group. OC lowers the free androgen index, in part, by substantially increasing SHBG levels. Despite a decrease in SHBG values after discontinuation of OC use, SHBG levels remained continuously elevated for up to one year in comparison with those in the control group. The free androgen index may remain low for a prolonged period.

The AACE Fourteenth Annual Meeting and Clinical Congress will be held May 18 through May 22, at the Marriott Wardman Park Hotel in Washington, DC.
