Currently being studied in many countries, the gel is rubbed onto the abdomen daily to suppress ovulation, but doesn’t stop periods. It contains Nesterone, a new form of progestin that does not bind to androgen receptors, so it is less apt than the pill to cause side effects such as acne. It also contains estradiol, a natural form of estrogen. “We did a study and women loved this product,” says Merkatz. A study of thousands of women will be needed before this gel can go on the market.
