Asexual and Sexual Reproduction
233
It appears that the sperm travel up the vagina into the uterus partly under their own power and partly by force of the inuscular contraction of the walls of these organs.34
Most of the sperm become lost on the journey,35 but a few find their way to the openings of the oviducts and swim up them, as suggested by the statement "Egajivassa...ikko...vã do vā tinni vä.... puttattāe havvamāgacchamti.''36
If ovulation has occurred shortly after or before copulation, the egg which passes into the oviduct probably will be fertilized by one of the sperm.37 "Only one of the millions of sperm deposited at each ejaculation fertilizes a single egg, 38 accordiog to modern Biology.
As soon as the egg has united with a sperm 39 it develops a fertilization membrane that prevents the entrance of others as is suggested by the fact that the unused sperm and unfertilized eggs die40 in the oviducts or uterus.
After fertilization has occurred, the zygote, while passing down the oviduct to the uterus, begins to divide.41 34. Pancabim thāņehimitthi purisena saddhim asamvasamāṇivi gabbham dharejjā,
