Summary Introduction
Introduction: Fertilization is the process of formation of diploid zygote from the haploid sperm and egg. There are molecules at the surface of the egg which regulates the every step of fertilization. The sperm has to penetrate the protecting layer of egg fuse with the plasma membrane.

Which hormones are present in largest concentration just before ovulation? During which part of the menstrual cycle is the endometrium most prepared to receive an embryo? Which hormones stimulate thickening of the endometrium? Gonadotropic hormones and ovarian hormones regulate the monthly sequence of events that take place within the ovary and uterus. The preovulatory phase begins with menstruation; the postovulatory phase begins after ovulation. Figure 50-14 Endocrine regulation of the menstrual cycle When fertilization does not occur, the menstrual cycle repeats about every 28 days. Note the changes in hormone concentrations that regulate the menstrual cycle.
