Which glands are primarily responsible for producing secretions that aid sperm activity?

Cervical and mammary glands.

Adipose and thyroid glands.

Pituitary and adrenal glands.

Genital ducts and accessory glands. (correct)

What happens to dihydrotestosterone during puberty?

It decreases testosterone levels significantly.

It begins to act on several tissues, including hair follicles. (correct)

Study Notes

Male Reproductive System

The male reproductive system comprises the testes, genital ducts, accessory glands, and the penis.
Testes produce sperm and hormones, including testosterone.
Testosterone drives male reproductive function.
Testosterone is crucial for:
- Spermatogenesis (sperm production)
- Sexual differentiation during embryonic and fetal development
- Regulating pituitary gland hormone secretion.
Dihydrotestosterone (a testosterone metabolite) is also essential.
Dihydrotestosterone affects tissue development, specifically male accessory glands and hair follicles during puberty.
Genital ducts and accessory glands produce secretions vital for sperm function.
These secretions propel sperm and provide them with necessary nutrients within the male reproductive tract.
Semen is a combination of sperm and secretions from accessory glands.
Semen is introduced into the female reproductive tract by the penis and contains needed nutrients for sperm.
Sperm movement and secretions are propelled via muscular contractile activity, including within the penile urethra.
