Progesterone causes the endometrial glands to secrete, preparing the endometrium for blastocyst implantation. If the oocyte is fertilized, the corpus luteum enlarges to form a corpus luteum of pregnancy and increases hormone production. With pregnancy, chorionic gonadotropin, secreted by the trophoblast of the chorion, prevents degeneration of the corpus luteum.
Fertilization and Implantation Symptoms. When the egg is ready for fertilization, it travels from the ovaries into the fallopian tube, where it will fertilize with the sperm if you have had unprotected sex in your fertile period of your cycle. This fertilized egg travels to the uterus and plants itself on the wall. This is called implantation. Implantation is the implanting of the fertilized egg or embryo or even called a blastocyst on to the uterine wall. It takes place about 2-3 weeks after ovulation. Soon after fertilization, symptoms also occur about 2-3 weeks after ovulation.
