1. Which of these is mismatched?
Multiple Choice
secretory phase - progesterone peaks
ovulation - luteinizing hormone (LH) peaks
menstruation - progesterone declines
proliferative phase - estrogen levels rise
menstruation - follicle-stimulating hormone (FSH) peaks
.
2. If a man has such severe infertility that his sperm are incapable of penetrating an oocyte and achieving fertilization, then the best assisted reproductive technology for him and his partner would be
Multiple Choice
ICSI.
IVF.
AID.
E.IUD.
GIFT.
.
3. Which of these places the events of the menstrual cycle in the correct order?
Multiple Choice
menstrual phase→ovulation→proliferative phase→secretory phase
menstrual phase→ovulation→secretory phase→proliferative phase
menstrual phase→proliferative phase→secretory phase→ovulation
menstrual phase→proliferative phase→ovulation→secretory phase
menstrual phase→secretory phase→proliferative phase→ovulation
.
4. What is the assisted reproductive technology that involves the placement of harvested sperm in a woman's (v)agina by a physician?
Multiple Choice
AID
IVF
IUD
GIFT
ICSI
.
5. Which of these is not part of the female reproductive system?
Multiple Choice
vas deferens
(v)agina
oviduct
ovary
uterus
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
It is present in male.
Other structures mentioned are present in females.
