Does Ovulation Occur During Lactational Amenorrhea?

Only when lactation declines sufficiently to allow generation of a normal preovulatory LH surge to occur will ovulation take place with the formation of a corpus luteum of variable normality.

Does lactation stop ovulation?

How does breastfeeding prevent pregnancy? When you exclusively breastfeed — meaning you nurse at least every 4 hours during the day and every 6 hours at night, and feed your baby only breast milk — your body naturally stops ovulating. You can't get pregnant if you don't ovulate.

Why ovulation does not occur during lactation?

Elevated prolactin levels and a reduction of gonadotropin-releasing hormone from the hypothalamus during lactation suppress ovulation. This leads to a reduction in luteinizing hormone (LH) release and inhibition of follicular maturation.
