WCHS Mr. Alasti HBS Human Body Systems 2.2.3 Reproductive Regulation

Hypothalamus

Produces releasing hormones & links the nervous system with the endocrine system (acts as a middleman)

Pituitary Gland

Master gland

What do ovaries secrete/produce?

The hormones estrogen and progesterone (help to regulate reproduction & menstruation)

What do testes secrete/produce?

Sperm & testosterone (helps with the growth of the male body)

Advantages of peer review

• Other scientists will critique it and tell you what to fix

• Help to ensure there is no bias

Disadvantages of peer review

• Takes a long time

• They won’t publish or review it if they don’t think it’s worthy

Testosterone

Builds bone & muscle mass, promotes body hair growth, & the development of reproductive tissue; made in the testes and ovaries

New, better ways to share information

• Everybody in the scientific community can critique it

• It is a lot more efficient

• Still accomplish it, getting turned into a journal

• The information can be fake

Estrogen

Plays a role in puberty, menstruation, pregnancy, menopause, sperm development, & bone health; made in the ovaries, testes, adrenal glands, & fat cells

Progesterone

Plays a role in menstruation, pregnancy, & testosterone production; made in the ovaries, testes, and adrenal glands

Reproductive Endocrinologists

Gynecologists with special training, who focus on reproductive health & fertility

Maternal-Fetal Medicine Specialists

Sometimes include endocrinologists who focus on endocrine-related issues during pregnancy & with developing babies

Pediatric Endocrinologists

Pediatricians with special training who focus on growth, puberty, & other hormonal conditions that affect children

Endocrine disruptors

Substances that interfere with hormones and the endocrine system, and can be human made or naturally occurring. They can be found in everyday products such as packaging, toys, cosmetics, food, water, & the environment

List endocrine disruptors

• BPA

• Phytoestrogens

• Phthalates

• Triclosan

BPA

Endocrine disruptor that is used to make some plastics

Phytoestrogens

Endocrine disruptors that occur naturally in some plant products, like sesame seeds, flax seeds, tofu, and soy milk

Phthalates

Endocrine disruptors used to make plastics more flexible

Triclosan

Endocrine disruptor used as an antimicrobial in products like soaps, toothpaste, clothing, & toys
