Solutions

Expert Solution

1. Menstruation - FSH peaks is incorrect.

As FSH peaks on middle of cycle along with LH.

Other options are correct.

2. ICSI

Since sperms are incapable of penetrating an oocyte, we must adopt a method where sperms need not to penetrate. This method is ICSI or Intracytoplasmic Sperm Injection where sperms are injected into the cytoplasm of oocyte directly.

Other options do require, penetration of egg by sperms. So they are incorrect.

3. Menstrual phase > Proliferative phase > Ovulation > Secretory phase

4. GIFT

Gamete intrafallopian transfer (GIFT) is a tool of assisted reproductive technology against infertility. Eggs are removed from a woman's ovaries, and placed in one of the Fallopian tubes, along with the man's sperm.

5. Vas deferens
