Every 28 days female reproductive organ i.e. each ovary will release a ovum(egg), that ovum is called by a finger like projection called Fimbriae, the ovum is carried through the oviduct, if the ovum is fertilised by a sperm the process of implantation of zygote into endometrium will follow which is called PREGANANCY,.
