The flow of blood and uterine lining
Top portion of the uterus across from the cervix.
The production of ova (eggs), including meiosis and maturation.
A pregnancy in which the embryo (blastocyst) implants and beings development in a location other than the uterus, most commonly in an oviduct (a tubal pregnancy).
A hormone secreted by the anterior pituitary gland that in females stimulates ovulation and the formation of the corpus luteum (which produces estrogen and progesterone) and prepared the mammary glands for milk production. In males, it stimulates testosterone production by the interstitial cells within the testes.
LH (luteinizing hormone)
A painful condition in which tissue from the lining of the uterus (the endometrium) is found outside the uterine cavity.
The inner layer of the uterus consisting of connective tissue, glands, and blood vessels. It thickens and develops with each menstrual (uterine) cycle and is then lost as menstrual flow. It is the site of embryo implantation during pregnancy.
A hollow muscular organ in the female reproductive system in which the embryo implants and develops during pregnancy.
The narrow neck of the uterus that projects into the vagina whose opening provides, a passageway for materials moving between the vagina and the body of the uterus.
Hormonal Birth Control Methods
A collection of uncomfortable symptoms, including irritability, stress, and bloating, that appears (seven) to 10 days before a woman's menstrual period and is associated with hormonal cycling.
PMS (premenstrual syndrome)
A sterilization procedure in men in which the vas deferens on each side is cut and sealed to prevent sperm from leaving the man's body.
A sex hormone produced by the corpus luteum in the ovary. Progesterone helps prepare the endometrium (lining) of the uterus for pregnancy and maintains the endometrium.
Used to help keep women from getting pregnant after intercourse.
A steroid sex hormone produced by the follicle cells and the corpus luteum in the ovary. Estrogen helps oocytes mature, stimulates cell division in the endometrium and the breast with each uterine cycle, and maintains secondary sex characteristics. The adrenal cortex secretes estrogen.
The end of a female's reproductive potential when ovulation and menstruation cease.
A means of contraception that consist of sperm-killing chemicals in some form of a carrier, such as foam, cream, jelly, film, or table.
A sterilization procedure in females in which each oviduct is cut and sealed to prevent sperm from reaching the eggs.
A means of contraception consisting of a small plastic device that either is wrapped with copper wire or contains progesterone. It is inserted into the uterus to prevent pregnancy.
IUD (intrauterine device)
A muscular tube in the female reproductive system that extends from the uterus to the vulva and serves to receive the penis during sexual intercourse and as the birth canal.
A structure in the ovary that forms from the follicle cells remaining in the ovary after ovulation. Functions as an endocrine structure that secretes estrogen and progesterone.
Tubes that conduct the ova from the ovary to the uterus in the female reproductive system. Also called uterine tubes or fallopian tubes.
The sequence of events in the ovary that leads to ovulation. The cycle is approximately 28 days long and is closely coordinated with the menstrual cycle.
The release of the secondary oocyte from the ovary.
A mature follicle in the ovary.
