Puberty in females is delayed who are:

1. active and have high body fat

2. active and have low body fat

3. sedentary and with high body fat

4. sedentary with low body fat

Identify the correctly matched pair:

An unpaired human male accessory gland/duct is:

1. seminal vesicle

2. vas deferens

3. bulbourethral gland

4. prostate gland

The secretion of paired seminal vesicles include:

1. sperm cells.

2. acidic plasma.

3. fructose-rich fluid.

4. androgens

Cremaster muscle:

1. elevates the testes during exposure to cold.

2. surrounds testes on all sides.

3. plays no role in thermoregulation.

4. pushes sperms into the rete testes.

Sperm-producing cells have unique antigens yet they are not attacked by the immune cells because of:

Spermatic cord does not include:

1. testicular artery.

2. lymphatic vessels.

3. ductus deferens.

4. ejaculatory duct.

Cryptorchidism may lead to sterility due to:

1. relatively high internal body temperature.

2. excessive production of estrogen.

3. lack of testosterone.

4. non-function of the SRY gene.

In males, the secondary sexual characters develop in response to:
1. ICSH
2. FSH
3. testosterone
4. gonadotropin-releasing hormone

In males, FSH:

1. inhibits progesterone.

2. initiates testosterone production.

3. increases protein synthesis.

4. increase spermatogenesis.
