What Hormones Are Involved in Ovulation?
Ovulation is the process by which an ovum, or egg, is released from a woman’s ovaries. Ovulation usually occurs once every menstrual cycle. The ovum travels down the fallopian tube where it is able to be fertilized. If it is fertilized, it travels to the uterus where it may or may not implant, causing a pregnancy. If an ovum is not fertilized, it disintegrates as it travels through the end of the fallopian tube. Follicle Stimulating Hormone (FSH) When a women’s menstrual cycle starts, after her period ends, the body releases follicle stimulating hormone (FSH). This hormone tells the ovary to begin maturing follicles, which will become the ovum. Estrogen As the follicles develop, one will mature fully, while the others will disintegrate. The follicles release estrogen as they mature. When there is a high level of estrogen, the body knows an ovum is mature and ready to be released. Luteinizing Hormone When an ovum is mature, luteinizing hormone will be released; this signals the ovary to
