Reproduction in Human Beings
• Humans use sexual mode of reproduction.
• Sexual maturation : The period of life when production of germ cells
i.e., ova (female) and sperm (male) start in the body. This period of
sexual maturation is called puberty
Female Reproductive System
(a) Ovary : A pair of ovary is located in both sides of abdomen.
• Female germ cells i.e., eggs are produced here.
• At the time of birth of a girl, thousands of immature eggs are present
in the ovary.
• At the onset of puberty, some of these eggs start maturing.
• One egg is produced every month by one of the ovaries.
(b) Oviduct or Fallopian tube
• Receives the egg produced by the ovary and transfer it to the uterus.
• Fertilisation i.e., fusion of gametes takes place here.
(c) Uterus : It is a bag-like structure where development of the baby takes
Male Reproductive System
(a) Testes : A pair of testes are located inside scrotum which is present
outside the abdominal cavity. Scrotum has a relatively lower temperature needed
for the production of sperms.
• Male germ cell i.e., sperms are formed here.
• Testes release male sex hormone (testosterone). Its function is :
(i) Regulate production of sperms.
(ii) Bring changes at puberty.
(b) Vas deferens : It passes sperms from testes upto urethera.
(c) Urethera : It is a common passage for both sperms and urine. Its outer
covering is called penis.
(d) Associated glands : Seminal vesicles and prostate gland add their
secretion to the sperms. This fluid provide nourishment to sperms and make their
transport easy.
Sperm alongwith secretion of glands form semen.
