Question | Answer |
---|---|
Activating effect | temporary effect of a hormone on behavior or anatomy, occurring only while the hormone is present |
Alpha-fetoprotein | protein that binds with estrogen in the bloodstream of many immature mammals |
Androgen | class of steroid hormones that are more abundant in males than in females for most species |
Androgen insensitivity | condition in which a person lacks the mechanism that enables androgens to bind to genes in a cell's nucleus |
Congenital adrenal hyperplasia (CAH) | overdevelopment of the adrenal glands from birth |
Estradiol | one type of estrogen |
Estrogen | class of steroid hormones that are more abundant in females than in males for most species |
Follicle-stimulating hormone (FSH) | anterior pituitary hormone that promotes the growth of follicles in the ovary |
Gender identity | sex with which a person identifies |
Hermaphrodite | individual whose genitals do not match the usual development for his or her genetic sex |
Impotence | inability to have an erection |
Intersex (or pseudohermaphrodite) | individual whose sexual development is intermediate or ambiguous |
Luteinizing hormone (LH) | anterior pituitary hormone that stimulates the release of an ovum |
Menstrual cycle | in women, periodic variation in hormones and fertility over the course of approximately 1 month |
Müllerian ducts | early precursors to female reproductive structures (the oviducts, uterus, and upper vagina) |
Organizing effect | long-lasting effect of a hormone that is present during a sensitive period early in development |
Ovaries | female gonads that produce eggs |
Oxytocin | hormone released by the posterior pituitary; also a neurotransmitter; important for sexual and parental behaviors |
Periovulatory period | time just before and after the release of the ovum, when fertility is highest |
Progesterone | steroid hormone which, among other functions, prepares the uterus for the implantation of a fertilized ovum and promotes the maintenance of pregnancy |
Sensitive period | time early in development during which some event (e.g., an experience or the presence of a hormone) has a strong and long-lasting effect |
Sexually dimorphic nucleus (SDN) | part of the medial preoptic nucleus of the hypothalamus, larger in males than in females and linked to male sexual behavior |
SRY gene | sex-region Y gene, which causes the primitive gonads to develop into testes |
Steroid hormone | hormone that contains four carbon rings |
Testicular feminization | See Androgen insensitivity |
Testis | male gonad that produces testosterone and sperm |
Testosterone | one type of androgen |
Wolffian ducts | early precursors to male reproductive structures |
