1st day of menstruation and lasts 12-14 days, during this phase the graafian follicle is maturing under the influence of two pituitary hormone: luteinizing hormone (LH) and follicle-stimulating hormone (FSH), the mature graafian follicle produces estrogen
begins when estrogen levels peak and ends with the release of the oocyte (egg) from the mature graafian follicle-referred to as ovulation
women's menstrual cycle: luteal phase
begins after ovulation and lasts approximately 14 days
-during this phase the cells of the empty follicle undergoes changes and form into the corpus luteum.
pertains to the changes in the endometrium of the uterus in responses to the hormonal changes that occur during the ovarian cycle-consists of 3 phases
-proliferative phase: following mestruation and ends with ovulation, during this phase the endometrium is preparing for implantation by becoming thicker and more vascular-due to the increasing levels of estrogen produced by the graafian follicle.
-secretory phase: begins after ovulation and ends with onset of mestruation. during this phase the endometrium continues to thicken, primary hormone is progesterone secreted from the corpus luteum.
-menstrual phase: occurs in response to hormonal changes and results in the sloughing off of the endometrial tissue.
(fertilization) occurs when the sperm nucleus enters the oocyte.
