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