*usually only one of the developing follicles which burst

*maturing follicles which are not ovulated deteriorate rapidly

*the second meotic division occur only if sperm penetrates the secondary oocytes

*the polar bodies has no cytoplasm

*the function of polar bodies is to contain half of chromosomes

*if fertilization does occur,the embryo produces a hormone very similar to LH

*human chorionic gonadotropin causes the corpus luteum to continue producing its hormone

*lack of ovarian hormones causes the blood vessels of endometrium to go into spasm

*ovulation occurs at the end of proliferative stage

* proliferative stage of uterine cycle results from rising estrogen level

*secretory stage of uterine cycle results from rising progesterone level

*at puberty,production of ovarian hormones begin

*progesterone does not contribute to secondary sex characters

*during pregnancy,placenta is the main source of progesterone

*mammary glands are modified sweat glands

*second meotic division occur after the sperm penetrate the oocyte

*fertilization leads to zygote formation

*zygote is the first cell of the new individual

*rapid mitotic division begins after fertilization

*implantation is usually completed 14 days after after ovulation

*the most common reproductive problems in adults is infection
