1. Sperm: 1 pair of ovary about 2 inches long. The ovaries are enclosed in a sac called scrotum and when attached to the sperm, it hangs like an appendage in the groin of both legs. Inside the scrotum the two testicles are located side by side. The weight of the testicles is 10-12 grams. It produces sperm and secretes the hormone testosterone.
2. Epididymis: It separates the liquid and solid waste from the sperm and increases their fertilization capacity and keeps the sperm fresh by secreting nutrients. 3. Vas deferens or spermatozoa: It transports sperm quickly during intercourse. Sometimes it also works to store sperm.
4. Seminal vesicle: It secretes a large amount of semen or semen to produce semen. The secreted fructose acts as a source of energy for the active sperm.
5. Ejaculation duct: Ejaculation duct delivers sperm to the urethra with secretion of seminal sac.
6. Urethra: Semen is excreted through this duct and urine is excreted.
7. Scrotum: The scrotum protects the optimal temperature for sperm production. It also protects the testicles from stress-induced damage.
8. Penis: The penis is an external part of a man through which the urethra is exposed and exposed. There is no fat under the skin but there is thin tissue. That is why the skin of the penis is so loose.There are a few tufts of hair. The part of the penis that hangs is the penis. At the tip of the frog's umbrella-shaped red mundi is called Glans Penis. It has the most nerve endings exposed. The skin that covers the mundi. It is cut off by circumcision.The penis consists of two types of erectile tissue. When this tissue is strong, the penis expands. In the process of reproduction, it becomes strong and expands and it sends semen through the urethra to the inside of the female reproductive system.
9. Prostate gland: This is a kind of alkaline fluid secreted from the gland which increases the amount of semen juice and nourishes the sperm. Moreover, this fluid helps the sperm to survive by soothing the acidic condition inside the vagina.
10. Balbourethral: This is a pea-like gland located on either side of the urethra from which the duct exits and joins the urethra. This gland secretes mucus (lubricant) during intercourse.
