What is the primary function of Leydig cells in the testes?
Support spermatogenesis
Secrete inhibin
Produce testosterone
Convert testosterone to DHT
What is the role of Sertoli cells in the seminiferous tubules?
Provide structural and nutritional support to germ cells
Stimulate spermatogonia to enter meiosis
Secrete testosterone
Release hCG during early development
In the male reproductive system, where does sperm acquire motility and fertilizing capability?
Seminiferous tubules
Epididymis
Vas deferens
Prostate gland
What is the function of the acrosome in a mature sperm cell?
Releases enzymes to penetrate the ovum
Forms the blood-testes barrier
Contains mitochondria for energy
Protects DNA from reactive oxygen species
What structure secretes mucus and neutralizes the acidic pH of the male urethra?
Prostate gland
Epididymis
Bulbourethral gland
Seminal vesicle
What hormone stimulates granulosa cells to convert androgens to estrogens?
LH
Progesterone
FSH
GnRH
Which hormone triggers ovulation during the menstrual cycle?
LH
Progesterone
FSH
Estradiol
How does estrogen exert positive feedback during the menstrual cycle?
By inhibiting LH and FSH secretion
By stimulating GnRH and LH secretion
By promoting corpus luteum regression
By suppressing GnRH pulse frequency
During the luteal phase of the menstrual cycle, progesterone is primarily produced by:
Theca cells
The dominant follicle
Granulosa cells
The corpus luteum
Which of the following correctly matches male and female reproductive cell counterparts based on function and hormone responsiveness?
Sertoli cells – Theca cells; Leydig cells – Granulosa cells
Sertoli cells – Granulosa cells; Leydig cells – Theca cells
Sertoli cells – Oogonia; Leydig cells – Corpus luteum
Spermatogonia – Granulosa cells; Leydig cells – Zona pellucida
A patient has a mutation causing nonfunctional FSH receptors. Which of the following would most likely occur in a female?
Increased androgen production by granulosa cells
Inability to produce progesterone after ovulation
Impaired conversion of androgens to estrogens
Early menopause due to follicular exhaustion
In a male, why does exogenous testosterone supplementation often lead to infertility?
It increases sperm motility too early
It increases estrogen via aromatization, which damages Sertoli cells
It suppresses GnRH, LH, and FSH, reducing intratesticular testosterone
It decreases androgen-binding protein in Sertoli cells directly
