Conventional IVF

As compared with natural fertilization, sperm selection is less stringent in in vitro fertilization (IVF) because the fertilizing spermatozoon does not need to penetrate through the cervical mucus and to make its path along the female genital tract until it meets the oocyte. Hence, the probability of fertilization with less motile and less viable spermatozoa is higher. However, nonprogressively moving and immotile spermatozoa are still excluded as well as spermatozoa with defective function of binding sites for the zona pel-lucida and oolemma on their plasma membrane and those with abnormal acrosomal function.
