The pill may cause permanent sex drive loss

University of Boston researches are reporting that the birth control pill can cause permanent loss of sex drive:

It has been long known that oral contraceptives lower levels of testosterone, and thus sex drive, and increase levels of sex hormone binding globulin, or SHBG

While it was thought that the pill's adverse effects could be reversed, the University of Boston research shows they may be permanent, the London Daily Mail reported Thursday...

...Women taking the pill had SHBG levels that were seven times higher than women who had never taken oral contraceptives.

Women who quit taking the pill still registered SHBG levels that were four times as great as non-contraceptive users.

Yet another reason to think twice before disrupting natural and complex physiological systems.
