(i) Parturition (ii) Ovulation
(iii) Spermatogenesis (iv) Gestation
(ii) Ovulation: The process of release of an egg from the ovary is called ovulation.
(iii) Spermatogenesis: The production and development of sperms is called spermatogenesis.
(iv) Gestation: The period in which an embryo develops in the uterus is called gestation.
