Question

Intensely lactating mothers do not generally conceive due to the [NCERT Exemplar]
(a) suppression of gonadotropins.
(b) hyper secretion of gonadotropins.
(c) suppression of gametic transport.
(d) suppression of fertilisation.

Answer 1

Answer:

A

Explanation:

Breast feeding is one of the natural contraceptive methods. It reduces fecundity by affecting the production of certain reproductive hormones. It is known to suppress the production of Gonadotropin-Releasing Hormone (GRH) and Follicle Stimulating Hormone (FSH). The release of these hormones triggern ovulation. Breast feeding also leads to increased level of prolactin, a hormone that inhibits ovulation. So, even when a woman ovulates, her likelihood of conceiving is low if she is breast-feeding.
