1. Organ where sperm encounters the egg cell:
The sperm encounters the egg cell in the fallopian tube (also known as the oviduct) of the female reproductive system. Fertilization occurs here when the sperm meets and fuses with the egg.
2. What will happen if it is blocked?
If the fallopian tubes are blocked: - The sperm cannot reach the egg. - Fertilization will not occur, resulting in infertility.
3. Technique to block the fallopian tubes:
The fallopian tubes can be blocked intentionally using a surgical procedure called tubectomy (or tubal ligation). It is a permanent method of contraception where the fallopian tubes are cut or tied to prevent the egg from traveling to the uterus.
