Role of organs in the human male reproductive system:

1. Testes

• Produce the male gametes, sperms
• Produce the male sex hormone, testosterone

2. Seminal vescicles:

• The secretion of seminal vesicles contains fructose, hormones like prostaglandins and clotting proteins.
• Fructose acts as a source of energy for the sperms.
• Prostaglandins stimulate uterine contractions and help in the movement of sperms towards the fallopian tube of females.
• The clotting proteins help semen coagulate after ejaculation.
• Alkaline nature of the seminal fluid helps to neutralise the acidic environment of the male urethra as well as the female reproductive tract that would otherwise inactivate and kill sperms.
