These levels peak during orgasm and induce peristaltic contractions of the uterus and oviducts which help transport sperm toward the ovum. Increases in this peptide hormone/neuropeptide predicted more affectionate contact with offspring.
compared to most female primates, women's observable phenotypes are less tethered to cyclic fluctuations in ______________.
The timing of menarche is influenced by female biology, as well as genetic and environmental factors, especially nutritional factors.
______________ declines during caloric shortage. It is the major female sex hormone. It is involved in the regulation of female reproductive cycles, the development of female secondary sexual characteristics and the development and maintenance of female reproductive tissues.
early development, puberty, pregnancy, mothering, nursing and menopause are all examples of this type of hormonal changes
the proportion of individuals experiencing attraction to women.
associated with stress, may lower fertility.
Placental estrogens and _____________ inhibit ovulation. (Hint #2) Changes in attractiveness appear to be driven by estradiol and _____________ which may reflect
changing facial shape, skin oiliness, skin color, acne or subtle differences in facial expression, such as smiling.
Changes in _____________ predicted diurnal changes in attractiveness. _____________ is the primary male sex hormone and androgen in males. In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. It is associated with increased aggression, sex drive, dominance, courtship display, and a wide range of behavioral characteristics.
Hormones orchestrate and coordinate human female sexual development, ________________, and reproduction in relation to three types of phenotypic changes (life history transitions, responses to contextual factors, and cyclical patterns). The distinctive aspects of
women's ________________ such as the possession of sexual ornaments, relatively cryptic fertile windows extended sexual behavior across the ovulatory cycle, and a period of midlife reproductive senescence are discussed in this article.
this development starts with fertilization, in the germinal stage of embryonic development, and continues in fetal development until birth.
Hormones orchestrate and coordinate human female sexual development, _____________, and reproduction in relation to three types of phenotypic changes (life history transitions, responses to contextual factors, and cyclical patterns). The distinctive aspects of
women's ____________ such as the possession of sexual ornaments, relatively cryptic fertile windows extended sexual behavior across the ovulatory cycle, and a period of midlife reproductive senescence are discussed in this article.
steroid hormones that increase in both males and females during puberty. Testosterone is the major steroid hormone in males. Dihydrotestosterone (DHT) and androstenedione are of equal importance in male development.
This is a protein known to induce lactation and maternal behavior. Reports also suggested that women's preferences for masculine traits might correlate negatively with progesterone, and positively with estradiol and _____________.
