Where are gametes produced in the human body?

• In the prostate gland and seminal vesicles

• In the seminiferous tubules and ovaries

• In the hypothalamus and pituitary gland

• In the interstitial cells and follicles

What is the role of the prostate gland and seminal vesicles in the reproductive system?

• They secrete fluids that maintain the mobility and viability of the sperm.

• They produce gametes.

• They secrete hormones.

• They stimulate the pituitary gland to release hormones.

Which hormones are released by the pituitary gland to control reproduction?

• Testosterone and estrogen

• Follicle stimulating hormone (FSH) and luteinising hormone (LH)

• Interstitial cell stimulating hormone (ICSH) and releaser hormone

• Progesterone and oxytocin

What is the function of testosterone in sperm production?

• It decreases the mobility and viability of sperm.

• It stimulates sperm production and activates the prostate gland and seminal vesicles.

• It inhibits the release of FSH and ICSH from the pituitary gland.

• It stimulates the production of ova in the ovaries.

How long does the menstrual cycle typically last?

• 14 days

• 28 days

• 21 days

• 35 days

What hormone stimulates the proliferation of the endometrium during the menstrual cycle?

• Progesterone

• Luteinizing hormone (LH)

• Follicle-stimulating hormone (FSH)

• Oestrogen

During which phase of the menstrual cycle does the follicle develop into a corpus luteum?

• Menstrual phase

• Follicular phase

• Ovulation phase

• Luteal phase

What is the result of the negative feedback effect of ovarian hormones on the pituitary gland?

• Increased secretion of FSH and LH

• Decreased secretion of FSH and LH

• Unchanged secretion of FSH and LH

• Intermittent secretion of FSH and LH

What leads to menstruation at the end of the menstrual cycle?

• A surge in oestrogen levels

• A surge in LH levels

• Degeneration of the corpus luteum and a drop in progesterone levels

• Fertilization of the egg

How long is the female fertility cycle usually restricted to after ovulation?

• 1-2 days

• 3-4 days

• 5-6 days

• 7-8 days
