1.Luteinizing hormone is maximum in the blood during which stage of the ovarian cycle? (MDCAT 2022)
Correct answer: (c) ovulation
The LH surge is what triggers the release of the ovum.
2.The term menopause means: (MDCAT 2023)
Correct answer: (c) stop of ova production
The ovaries stop releasing ova and the cycles come to an end.
3.The production of follicle-stimulating hormone and luteinizing hormone from the pituitary gland of the female is controlled by the: (MDCAT 2023)
Correct answer: (d) hypothalamus
Gonadotrophin releasing hormone from the hypothalamus governs the anterior pituitary.
4.The corpus luteum during the female reproductive cycle produces: (MDCAT 2024)
Correct answer: (d) progesterone
Progesterone from the corpus luteum holds the uterine lining ready for implantation.
5.Due to the process of follicle atresia: (MDCAT 2024)
Correct answer: (b) the follicle degenerates
All but one of the follicles recruited in a cycle break down, and that breakdown is atresia.
6.During menstrual cycle, luteinizing hormone (LH) is secreted due to; (UHS MDCAT 2025)
Correct answer: (c) Increase in FSH
Rising FSH raises the oestrogen of the growing follicle, and that in turn triggers the LH surge.
7.In a normal 28 days menstrual cycle when would you expect the LH surge to occur? (UHS MDCAT 2025)
Correct answer: (b) Days 11-14
The LH surge comes just before ovulation, about day 12 to 14 of a 28 day cycle.
8.Which changes occur in the endometrium during the proliferate phase of the menstrual cycle? (SIBA MDCAT 2025)
Correct answer: (b) It regenerates and thickens
Under rising oestrogen the lining left after menstruation is rebuilt and thickened.
9.If fertilization does not occur, which part of uterus degenerate? (SIBA MDCAT 2025)
Correct answer: (b) Endometrium
Without implantation the corpus luteum fails, oestrogen and progesterone fall, and the endometrium is shed.
10.In human female normally ovulation occurs at day _____ of menstrual cycle. (SZABMU MDCAT 2025)
Correct answer: (c) 14
Ovulation falls on about the fourteenth day of a twenty-eight day cycle.
11.Decreased level of FSH hormone during menstrual cycle triggers the release of: (SZABMU MDCAT 2025)
Correct answer: (b) LH
As FSH falls the ripe follicle drives the LH surge that brings on ovulation.
12.Corpus luteum during female reproductive cycle produces (UHS MDCAT 2024)
Correct answer: (d) Progesterone
The corpus luteum secretes progesterone, which holds the endometrium ready.
13.The corpus luteum is essentially formed from (KMU MDCAT 2024)

What is left of the Graafian follicle after ovulation becomes the corpus luteum.
14.Choose the mismatched pair: (NUMS MDCAT 2024)
Correct answer: (a) Graffian follicle - progesterone
The Graafian follicle secretes oestrogen; progesterone comes from the corpus luteum it becomes.

16.A hormone that plays a major role in social bonding, childbirth, milk ejection and sexual reproduction is: (UHS MDCAT 2023)
Correct answer: (b) Oxytocin
Oxytocin drives the contractions of labour and the let-down of milk.
17.Hormone produced by placenta is: (UHS MDCAT 2023)

24.What is true about Ozytocin? (UHS MDCAT 2023)
Correct answer: (d) Dilate milk ducts of mammary glands
Oxytocin contracts the muscle round the milk ducts, so the milk is let down.

35.In a typical menstrual cycle of 28 days, what is the most likely fertile period? (PMC Practice 2021)
Correct answer: (d) Days11to14
Ovulation falls about day fourteen and the ovum lives only a day, so the fertile days are just before it.
