Question

The process of fertilization in humans is practically possible in which of the following cases?

A) When the sperm is transported to the cervix within 72 hours of release of ovurn in the fallopian tube.

B) The ovum and sperms are transported simultaneously to the ampullary-Isthmic junction of the oviduct

C) The ovum and sperms are transported simultaneously to the endometrium lining of the uterus

D) The sperms are transported into the vagina just after the release of ovum in the fallopian tube​

Answer 1

Answer:

When the sperm is transported to the cervix within 72 hours of release of ovurn in the fallopian tube.

Explanation:

The process of fertilization in humans isisthmic junction of the fallopian tube

Ampulla averages 5–8 cm in length. It is within this highly ciliated portion of the oviduct that fertilization and early embryo development occur. The ampulla is most often also the site for ectopic implantation (ectopic pregnancy). The next region, approximately 2–3 cm in length, is the isthmus. Like the ampulla, it too is ciliated yet less densely so. The isthmus is thought to regulate sperm and embryo transport.

So, the correct option is 'the ovum and sperms are transported 'simultaneously to ampullary - isthmic junction of the fallopian tube'
