What are the primary reproductive hormones in males and females, and their main functions?

In males, testosterone is produced in the testes and stimulates sperm production.

In females, oestrogen is produced in the ovaries and plays a key role in the menstrual cycle.

What are secondary sex characteristics, and when do they develop?

Secondary sex characteristics, such as facial hair in boys and breast development in girls, develop during puberty due to the release of hormones.

What happens during Stage 1 of the menstrual cycle?

Stage 1 begins on day 1 with menstruation if there is no fertilised egg, leading to the breakdown of the uterus lining for about 5 days.

What is ovulation and when does it occur in the menstrual cycle?

Ovulation is the release of an egg from the ovary, occurring around day 14 of the menstrual cycle.

What role does Follicle-Stimulating Hormone (FSH) play in the menstrual cycle?

FSH is produced in the pituitary gland, causes egg maturation in the ovaries, and stimulates the ovaries to start releasing oestrogen.

How does progesterone function in the menstrual cycle?

Progesterone is produced by the ovaries and helps to maintain the uterus lining.
