Biology Question on Reproductive Health – Problems And Strategies
What is the work of progesterone which is present in oral contraceptive pills:
To inhibit ovulation
To check oogenesis
To check entry of sperms in to cervix to make them inactive
To check sexual behaviour
To inhibit ovulation
Solution
Progesterone in oral contraceptive pills primarily works to inhibit ovulation, preventing the release of eggs from the ovaries. It does this by suppressing the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland, which are essential for the ovulation process. Additionally, progesterone thickens cervical mucus, making it more difficult for sperm to reach and fertilize an egg. It also alters the uterine lining, making it less receptive to implantation, further preventing pregnancy.
So, the correct option is (A): To inhibit ovulation
