reproductive behaviors for biological psychology
| 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 |
