Folk contraceptives lead researchers to drugs that block fertilization

(University of California - Berkeley) Most contraceptives include steroid hormones at concentrations that can produce side effects in women. UC Berkeley scientists have now found two non-steroid chemicals that are effective at lower doses, potentially providing a better option. The researchers also found that testosterone and the stress hormone cortisol work the same way as these compounds, by blocking the power kick sperm need to penetrate the egg. This may explain why high testosterone and stress lower fertility.
