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
