I learned about this yesterday, and I expect a number of news sources will report on it. Keep your eye out, because the blurb I read did not clarify if a causal relationship had been established and whether this is a problem for all women or just those with sexual dysfunction. I have lifted the following from a press release:
Hormonal changes induced by oral contraceptives are not immediately reversible after discontinuation of use, according to new research issued at the American Association of Clinical Endocrinologists Fourteenth Annual Meeting and Clinical Congress.
Despite the benefits of oral contraceptives, their use has been associated with sexual dysfunction and androgen insufficiency. In the study of 102 pre-menopausal women with female sexual dysfunction, sex hormone-binding globulin (SHBG) values in the contraceptive group were seven times higher than those in the never-user group.
Oral contraceptives lower the free androgen index, in part, by substantially increasing SHBG levels. Despite a decrease in SHBG values after discontinuation of contraceptive 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.
