A hormone that is produced by the testicles (and in very small amounts by the ovaries and adrenal glands).
A hormone that is produced by the ovaries (and in very small amounts by the testicles and adrenal glands).
A hormone that is produced in large amounts by the ovaries after ovulation. It prepares the endometrium of the uterus to nourish a fertilized egg.
A gonadotropin hormone released by the pituitary gland that stimulates the development of a follicle in a woman's ovary and the production of sperm in a man's testicles.
Follicle-stimulating hormone (FSH)
A gonadotropin hormone released by the pituitary glad that triggers ovulation in women and stimulates the production of male hormones in men.
Luteinizing hormone (LH)
A hormone released from the pituitary gland that stimulates milk production in the breasts.
A pituitary hormone associated with milk release, labor and orgasmic contractions, and erotic attraction and touch.
A hormone released by the hypothalamus in the brain that causes the pituitary gland to release the hormones FSH and LH.
Gonadotropin-releasing hormone (GnRH)
A hormone produced by the testicles and ovaries that inhibits release of follicle-stimulating hormone from the pituitary gland.
The monthly cycle of hormonal events in a woman that leads to ovulation and menstruation.
A sac in the ovary containing an ovum and surrounding follicular cells.
The monthly discharge of endometrial tissue, blood, and other secretions from the uterus that occurs when an egg is not fertilized.
The follicular cells that remain in the ovary after the follicle expels the ovum during ovulation. They begin to secrete progesterone in large quantities in the postovulatory stage.
Chemical substances secreted externally by animals that convey information to, and produce specific responses in, members of the same species.
The cycle of hormonal events that occurs in most nonhuman mammals. The females are sexually receptive ("in heat," or estrus) to males only during ovulation
Incorrect negative attitudes about menstruating women.
The absence of menstruation for 6 months or longer.
The term for a girl's first menstrual period
A group of physical and/or emotional changes that many women experience in the last 3 to 14 days before the start of a menstrual period.
Premenstrual syndrome (PMS)
A severe form of PMS that markedly interferes with social relations, work, or education.
Premenstrual dysphoric disorder (PMDD)
Heavy vaginal bleeding
The growth of endometrial tissue outside of the uterus.
A syndrome with symptoms of high fever, vomiting, diarrhea, and dizziness; caused by toxins produced by the Staphylococcus aureus bacterium.
Toxic shock syndrome (TSS)
Synthetic steroid hormones that combine the growth (anabolic) effects of adrenal steroids with the masculinizing effects of androgenic steroids.
Produce small amounts of testosterone, estrogen and progesterone.
Preovulatory phase when the pituitary secretes FSH and the follicle secretes estrogen.
Follicular or proliferative phase
The gland located at the base of the brain that secretes follicle-stimulating hormone and luteinizing hormone.
If an egg is fertilized by a sperm and implantation occurs, the corpus luteium is maintained by a hormone from the developing placenta called...
Human chorionic gonadotropin (HCG)
Postovulatory phase when the corpus luteum begins to secrete large amounts of progesterone
Cramps experienced for about a day during ovulation
