How do birth control pills (oral contraceptives) work?
They predict the time of ovulation precisely and pregnancy can be avoided.
They lower the amount of estrogen in the body.
They increase the amount of LH and FSH, which speeds up ovulation.
They prevent the fertilized egg from traveling to the uterus for implantation.
They inhibit the release of FSH and LH by a negative feedback mechanism, preventing ovulation.
Correct Answer:
They inhibit the release of FSH and LH by a negative feedback mechanism, preventing ovulation.
They work before ovulation in the cascade of events leading to pregnancy.

The blood-testis barrier is made up of ________ cells.
epithelial
Leydig
spermatogonia
Sertoli
Correct Answer:
Sertoli
The blood-testis barrier is made up of Sertoli cells.
The meiotically active cells in the testes lie in the ___________.
blood-testis barrier
