Question

What is the name of the process required to make sperm competent for in-vitro fertilization?

• A. Capacitation
• B. Syngamy
• C. Parturition
• D. Ovulation

Answer 1

The Correct Option is A

The correct answer is (A) Capacitation.

Capacitation is the process that sperm undergo in the female reproductive tract (or in vitro in laboratory conditions) to become capable of fertilizing an egg. It involves changes in the sperm's membrane and motility that allow it to penetrate and fertilize the oocyte (egg). This process is crucial for in vitro fertilization (IVF) to be successful.

Let's briefly go over the other options:

(B) Syngamy: This refers to the fusion of male and female gametes (sperm and egg) during fertilization, but it is not the process of making sperm competent for fertilization.

(C) Parturition: This refers to the act of giving birth, not related to the process of sperm becoming competent for fertilization.

(D) Ovulation: Ovulation is the release of an egg from the ovary, which is part of the female reproductive cycle, not the process related to sperm maturation.

Thus, the correct process required to make sperm competent for in vitro fertilization is (A) Capacitation.

Answer 2

Capacitation is the physiological process that sperm undergo to become capable of penetrating and fertilizing an egg, which is crucial for successful in-vitro fertilization.
