Solution
The correct option is C Uterus
Sperms are male gametes formed in the seminiferous tubules of the testis by a process called spermatogenesis. The sperms formed in the seminiferous tubules are immature and enter the epidydimis.
When a spermatozoa passes through the epididymis, it completes its functional maturation. In the vas deferens, the sperms can be stored for several months. During this time, the sperms remain in a state of inactivity with low metabolic rates.
For the sperms to become fully capable of fertilising an ovum, they have to undergo a process called capacitation. Capacitation can be referred to as a series of final changes that sperms undergo to be able to fertilize the secondary oocyte. It normally occurs in 2 steps.
First, the sperms become motile when they are mixed with secretions from the accessory male reproductive glands (these are the glands which secrete fluids that help in the nourishment and motility of the sperms). They are responsible for the transportation, maturation and storage of sperms.
Secondly, the sperms become capable of successful fertilisation when exposed to conditions in the reproductive tract of females.
In the female reproductive tract, capacitation is completed in the uterus, after which the sperms become fully capable of fertilising an oocyte in the ampulla of oviduct.
