Reproductive System
Hormones of Reproductive System
Female
Gonadotropin releasing hormone: released by hypothalamus in the brain to stimulate anterior pituitary gland to release LS and FSH
Follicle stimulating hormone: stimulates the development and maturation of primary follicle into secondary follicle
Luteinizing hormone: spike of hormone will trigger ovulation of the most mature follicle
Inhibin: decrease release of FSH by anterior pituiatry gland
Estrogen: primary female sex hormone released by follicle
Progesterone: triggers supression of the hypothalamus from releasing GnRH
Male Follicle stimulating hormone: at puberty stimulates sertoli cells for sperm production and maturation
Leutinizing hormone: stimulates seminiferous tubules to secrete testosterone
Both LS and FSH: released by anterior pituitary gland in the brain
Gonadotropin releasing hormone: released by hypothalamus in the brain to stimulate anterior pituitary gland to release LS& FSH
Testosterone: stimulates reproductive organ development and sex drive which causes secondary sex characteristics
Inhibin: released by the testes when high levels of testosterone are present to release stimulate hypothalamus to release GnIH to stop production of LS and FSH
Anatomy of Male Reproductive
Testes: primary male sex organ that produces sperm
Ductus system: delivery of male gamete
Epididymus
ductus deferens
urethra
Accesorry organ: secondarysex organs
seminal vesicle
Prostate gland
bulbourethral gland
External genetalia: Penis and scrotum
Spermatogenesis: production of sperm cells
Anatomy of Female Reproductive
Ovaries: primary sex organ
Ductus system: delivery of female gamete
uterine (fallopian) tube
uterus
vagina
External genitalia
mon pubis
labia
vestibule
clitoris
oogenesis: process of producing ova or egg cells
Major functions
Sexual reproduction: reproduction involving two parents(male and female)
Fertilization: fusion of egg and sperm produces a zygote
Events of Female hormonal cycles
Ovulation cycle: occurs in the ovaries leading to the maturation and ovulation of the mature oocyte
Follicular phase: Day 1-14
Ovulation: Day 14
Luteal Phase: Day 15-28
Uterine/ Menstrual Cycle: occurs in the uterus to prepare the uterus for implantation of the fertilized sperm
Menstruation: Day 1-5
Proliferative phase: Day 6-14
Secretary Phase: Day 15-28
Disorders of the Reproductive System
Sexually Transmitted Diseases (STDs)
Chlamydia
Gonorrhea
Syphilis
Viral and Parasitic STDs
Herpes
Scabies
