1. The Male Reproductive Organs - Anatomy

What are the parts of the male reproductive organs?

1. testicles
2. epididymis
3. scrotum
4. penis
5. accessory sex glands

What are the functions of the testicles?

The testicles have both endocrine and exocrine functions. They produce gametes (sperm) and sex hormones

Where are the testicles located?

The testicles are located in the scrotum, at the inguinal region. They are suspended by the spermatic cord.

What is the role of androgens and oestrogens in the descent of testicles during foetal development?

Androgens promote the descent of testicles, while oestrogens inhibit it. Late descent in equine gonads is due to high oestrogen levels in the blood of pregnant mares.

What are the components of the testicular parenchyma?

The testicular parenchyma consists of seminiferous tubules, which are the site of spermatogenesis, and interstitial tissue, primarily composed of Leydig cells that produce androgenic hormones

What is the function of the epididymis?

The epididymis is involved in sperm maturation and propulsion through peristaltic contractions. It is divided into three parts: head, body, and tail

What is the function of the scrotum?

The scrotum is a thermoregulatory organ for the testicles. It contracts in colder environments to bring the testicles closer to the body for warmth and relaxes in warmer environments.

What is the role of the penis?

The penis is the male copulatory organ. It undergoes enlargement during copulation. The mechanisms of enlargement vary among species, involving vascular or fibroelastic changes.

What are some of the accessory sex glands in males?

* Ampullary glands: Dilated terminations of the vas deferens that contribute to the ejaculate and store sperm suspensions.
* Vesicular glands: Located adjacent to the neck of the bladder and produce watery secretions.
* Prostate: Found within or external to the urethra and produces secretions.
* Bulbourethral glands: Small rounded structures that produce a discharge prior to coitus for cleansing.
