Question 1

Difference between prostate and bulbourethral glands

Answer 1

The prostate gland secretes a milky, nutrient-rich fluid that enhances sperm survival, while the Cowper’s glands secrete a clear, lubricating fluid to neutralize and prepare the urethra for sperm passage.

Question 2

Leydig cells

Answer 2

Produce testestrone

Question 3

Sertoli cells

Answer 3

Produce factors for sperm maturation

Question 4

The secondary oocyte spends most of its existence in which phase of meiotic division?

Answer 4

Metaphase II

Question 5

Cremaster muscle

Answer 5

helps thermoregulate the testes by bringing them closer to the body in a cold environment. The testes require careful thermoregulation slightly below core body temperature for successful spermatogenesis.

Question 6

Dartas muscle

Answer 6

Contracts to wrinkle skin and tighten, reducing the surface area of the scrotum when it’s cold

Question 7

Function of seminal vesicles

Answer 7

provides nutrients necessary for the survival of spermatozoa.

Question 8

When does estrogen has a positive vs negative feedback?

Answer 8

Estrogen has a positive feedback at high concentrations near the end of the follicular phase

Estrogen has a negative feedback during most of the menstrual cycle when oestrogen levels are low or high.

Question 9

What hormone causes a decrease in LH through negative feedback and thereby leads to the degeneration of the corpus luteum?

Answer 9

Progesterone has a negative feedback effect on the secretion of luteinizing hormone (LH) by the anterior pituitary and is secreted by the corpus luteum.
