How it works

Exclusive breastfeeding suppresses the hormones that trigger ovulation. High prolactin from frequent nursing keeps estrogen and progesterone low, preventing the return of menstrual cycles.

Ormeloxifene (centchroman) is a selective estrogen receptor modulator (SERM) that prevents pregnancy by inhibiting implantation of a fertilized egg in the endometrium. It does not suppress ovulation and does not contain estrogen or progestin. It is not FDA-approved in the US.
