Puberty and Male Infertility Overview

What is the primary function of testosterone during puberty?

Which hormone is responsible for stimulating testosterone production?

What is NOT considered a secondary sexual characteristic in males?

Which of the following factors can contribute to male infertility?

What is the role of the fallopian tubes in the female reproductive system?

Puberty

Puberty is the beginning of sexual maturity
Hormones play a key role in puberty
Testosterone causes primary and secondary male characteristics, and increases puberty
FSH (Follicle-stimulating hormone) is produced by the pituitary gland and stimulates meiosis in the testes.
LH (Luteinizing hormone) is produced by the pituitary gland and stimulates testosterone production.
Secondary sexual characteristics include growth of underarm and facial hair, development of the larynx (voice change), widening of shoulders, muscle growth, and increased sebum production.

Male Infertility

Male infertility is the inability to produce offspring
Causes include low sperm count, smoking, alcohol, marijuana, anabolic steroids, hormone deficiencies, mumps, and exposure to detergents or plastics.
Corrective measures include lifestyle and diet changes, reducing stress, hormone supplements, and IVF (in-vitro fertilization).

Female Reproductive System

Ovaries produce eggs (ova) along with estrogen and progesterone.
Fallopian tubes (oviducts) have funnel-shaped ends to catch the eggs, carry them to the uterus via ciliary movement, and peristalsis.

This quiz covers the fundamental aspects of puberty, focusing on the hormonal changes that occur during this crucial stage of development. It also explores male infertility, its causes, and corrective measures. Test your knowledge on these important topics related to human reproduction and development.
