The entire process of spermatogenesis from spermatogonium to mature spermatozoon takes approximately how long in humans?

A 24 days
B 48 days
C 74 days ✓
D 120 days

Correct answer: C. 74 days

Explanation

Spermatogenesis takes approximately 64-74 days (commonly cited as ~74 days in standard texts). The 24-day option confuses it with the duration of spermiogenesis alone. This duration is clinically relevant because azoospermic patients require at least this period after treatment before semen analysis can show recovery.

LH surge triggers ovulation in females. The LH surge is triggered by high estrogen levels through which mechanism?
During the luteal phase of the menstrual cycle, which hormone is primarily responsible for maintaining the endometrium in the secretory phase?
On day 14 of a 28-day menstrual cycle, there is a sharp LH surge lasting 36–48 hours. Which cellular event in the dominant follicle does the LH surge directly trigger?
Human chorionic gonadotropin (hCG) is produced by the syncytiotrophoblast from the day of implantation. Its primary physiologic role in early pregnancy is:
The LH surge that triggers ovulation is caused by positive feedback of estradiol on the hypothalamic-pituitary axis. This positive feedback mechanism is unusual because it requires estradiol concentration to exceed a threshold for a sustained duration. Which cellular mechanism in pituitary gonadotrophs underlies the sensitisation required for the LH surge?
In spermatogenesis, Sertoli cells provide an essential support function including the blood-testis barrier. Which intercellular junction type forms the blood-testis barrier and what is its functional significance?
During the mid-cycle LH surge, the granulosa cell shifts from oestrogen production to progesterone production. What molecular mechanism underlies this 'luteinisation' process?
Inhibin B is predominantly secreted by which gonadal cell type, and what is its specific feedback role in the male reproductive axis?
