Biology and Sexuality

1. Sex is determined early in life through chromosomes inherited from parents.
2. Individuals inherit 23 pairs of chromosomes, with one determining sex.
3. Early indifferent gonads differentiate into ovaries or testes.
4. The development of male and female reproductive structures involves three distinct processes.
5. At puberty, additional hormone events lead to maturation of the genitals and development of secondary sex characteristics.
6. Hormones in meat and dairy products can trigger earlier puberty.
7. Both males and females produce androgens and estrogens synthesized by cholesterol.
8. The female cycle involves the release of estrogen and progesterone to thicken the uterus lining in anticipation of pregnancy.
9. PMS and PMDD are likely related to hormonal fluctuations during the menstrual cycle.
10. Estrogen therapy can help regulate the most important brain region in relation to the ovarian system, serotonin and GABA.Key Points:
11. Hormones influence sexual activity and orientation in animals and humans.
12. Testosterone levels have the most influence on female sexual interest.
13. Androgens are related to competition and increase in anticipation of athletic competition.
14. Chromosomal abnormalities can affect sexual development and identity.
15. Sexual orientation refers to the stable attraction to members of a particular sex.
16. Physical cues such as facial symmetry and body odor influence sexual attraction.
17. Sexual attraction changes cyclically in females.
18. Appetitive behavior promotes, establishes, and maintains sexual interaction.
19. Testosterone is important for male and female sex drive.
20. Human females show receptivity throughout the menstrual cycle.1. Coupulation has four stages: excitement, plateau, orgasm, and resolution.
21. Men and women have different sexual response patterns.
22. Female orgasm has adaptive value for securing good genes.
23. Sexual dysfunction is often psychological in origin.
24. Brain structure, hormones, and genetics influence sexual orientation.
25. Biology and socialization interact to shape male and female behavior.
26. Prenatal hormones have an effect on organization and activation in cognitive development.
27. Males and females have different cognitive strengths and weaknesses.
28. Brain size does not necessarily correlate with abilities in certain tasks.
29. The areas of the brain that are bigger in each gender have more receptors for steroid sex hormones.1. Brain size doesn't correlate with abilities in certain tasks
30. Connectivity and density of the brain is a better parameter to measure
31. Brain structures involved in learning and memory differ significantly between sexes
32. Hormones like testosterone and estrogen can influence cognitive abilities
33. Stress is a better predictor of cognition/behavior than sex
34. Sexual reproduction allows for a bigger gene pool and spread of good mutations
35. Parental care benefits the survival of offspring
36. Parental care costs include danger to parents and investment in time and resources
37. Parental favoritism can advance a parent's fitness
38. Hormones like prolactin, vasopressin, and oxytocin are involved in parental care and pair bonding.
