MALE REPRODUCTIVE SYSTEM
Male reproductive system includes scrotum, testes, spermatic ducts, sex glands and penis.
These organs work together to produce sperm, male gamete and components of semen.
PRIMARY SEX ORGAN OF MALE
SECONDARY or ACCESSORY SEX ORGANS
- Vas deference
- Seminal vesicle
- Ejaculatory duct
- Cowper’s gland
EXTERNAL SEX ORGAN
These are oval organ.
Lie in scrotum, secreted at either end by spermatic cord.
Men have two testes
- Responsible for making primary male sex hormone , testosterone
- Generates sperm
Sac like organ made of skin and muscles.
Scrotum is made up of two side by side pouches, in each pouch testis located.
Located inferior to the penis in the pubic region.
- Smooth muscle of scrotum regulates the distance between the testes and the rest of the body.
- Scrotum relaxes to move testes away from the body’s heat when testes become too warm to support sperm production.
Conversely when temperature drop below scrotum contracts to move the testes closer to body’s heat.
It is a muscular duct that connects the epididymis and the ejaculatory ducts.
It helps in transport of sperm from the epididymis to the ejaculatory ducts.
Comma shaped, tightly coiled tube.found on the superior part of the testis.
It stores the sperm cells and transport if from the testes.
It is a pair of lumpy excrine gland.
Located posterior to the urinary bladder and anterior to the rectum.
Produce liquid portion of semen which contain proteins and mucus and alkaline pH to help sperm to survive in alkaline environment of vagina
Vas deference join with urethra at a structure called ejaculatory duct.
Expels sperm during ejaculation.
Walnut size exocrine gland.
Inferior end of the urinary bladder & surrounds the urethra.
Produces large amount of fluid to make semen
It passes through the prostate & ends at the external urethral orifice.
Located at the tip of penis
Pea sized exocrine gland
Interior to prostate & anterior to anus
Secret thin alkaline fluid which enters the urethra during ejaculation for flow of semen.
