Sometimes a sperm cell fertilizes a polar body rather than a secondary oocyte. An embryo does not develop, and the fertilized polar body degenerates. Why is a polar body unable to support development of an embryo?
What happens if an oocyte combines with sperm? Describe the processes involved in implantation. Mention what is occurring, where it is occurring, and any significant hormones involved. How does the zygote make its way through the uterine tube? Women who smoke cigarettes have an increased risk of ectopic pregnancy because the chemicals they absorb paralyze cilia all through the body. Explain.
Despite the presence of So many sperms in the vicinity of an egg cell, only one sperm enters the ovum. Why
