Reproduction and Development Flashcards
Testis
Male gonad
-Site of gamete formation and testosterone production
Epididymis
Site of sperm maturation and storage
Vas Deferens
Sperm transport
Ejaculatory Duct
Sperm transport
Urethra
Channel for ejaculation of sperm and excretion of urine
Seminal Vesicle
Secretes fructose-rich fluid that is the main component of semen
Prostate Gland
Secretes prostaglandins and buffers that are found in semen
Bulbourethral Gland
Secretes mucous to clear urethra and provide lubrication
Seminiferous Tubules
Site of sperm formation
Hormones involved in sperm formation (4)
- Gonadotropin-releasing Hormone (GnRH)
- Follicle Stimulating Hormone (FSH)
- Luteinizing Hormone (LH)
- Testosterone
Gonadotropin-releasing Hormone (GnRH)
Secreted from Hypothalamus
- Triggers secretion of LH and FSH (males)
- Stimulates production of LH and FSH (females)
Follicle Stimulating Hormone (FSH) in males
Secreted from pituitary
-Supports sperm production
Luteinizing Hormone (LH) in males
Secreted from pituitary
-Stimulates testosterone production
Testosterone
Secreted inside testes
- Controls structure and function of male reproductive tract
- Induces secondary sex characteristics and aggressive behavior
Menstrual Cycle Hormones (5)
- GnRH
- FSH
- LH
- Estrogen
- Progesterone
