LH- Luteinizing Hormone1. Promotes follicles2. Increases estrogen and Progestiniv. Estrogen / Progesterone1. Maintains endometrium/ UterusIX. Male Reproductive Anatomyl. Sperm Productioni. Occurs in Testisii. Sperm Maturation occurs somewhat in testis, Then in Seminal VesicleX. Hormone Regulation of Male ReproductionI. Endocrine Aspectsi. Pituitary releases hormones (stimulated by hypothalamus1. FSH Stimulates production of sperm2. LH stimulates production of androgensa. LH maintains consistent amount with the use of negative feedbackXI. Female Reproductive Anatomym. Egg Formationi. Ovaries1. Follicles2. Copus Luteumii. The process of meiosis has “pauses”iii. Hormones regulate egg production1. Reproductive cyclesa. 20-40 Days (28 Days)i. Ovarian Cycle – ovulationii. Menstrual –uterine- Cycle- Menstruation1. Day 1 – menstruation begins2. Day 5 – Growing folliclesa. Estrogen Increases3. Day 13/14 – Peak LH and FSHa. Ovulation4. Day 28/1 – Lowest Estrogen and Progesteronea. Menstruationn.
