male reproductive

• Organ ( testes and ovaries ) – produce reproductive cells or gametes ( sperm and ova )
• reproductive system - Responsible for survival and perpetuation of the species
• Gonads – primary sex organs
• ( gonads ) testes in males
• ( gonads ) ovaries in females
• gonads produce gametes ( sex cells ) and hormones
• sperm for male gametes
• ova or eggs for female gametes
• testes - two oval shaped glandular organ
• testes - functions: hormones & spermatogenesis
• ( testes ) tunica albuginea - capsule that surrounds each testis
• ( testes ) septa - extensions of the capsule that extends into the testis
• testosterone - is the most important hormone of the testes
• testosterone - stimulates reproductive organ development
• testosterone - underlies sex drive
• testosterone - causes secondary sex characteristics
• epididymis - found on the superior part of the testis and along posterior lateral side
• epididymis - functions: to mature and store sperm cells for at least 20 days
• ductus deferens ( vas deferens ) - forms passageway of the sperm cells from the epididymis in the testis to the urethra
• prostate gland - Walnut – shape body lying below the bladder surrounding the urethra and the two ejaculatory ducts
• prostate gland - It secretes a thin milky alkaline fluid that help to neutralize the acidic nature of male urethra caused by urine
• urethra - carries both urine and sperm
• prostatic urethra - surrounded by prostate
• membranous urethra - from prostatic urethra to penis
• spongy ( penile ) urethra - runs the length of penis
• seminal vesicle - located at the base of the bladder
• seminal vesicle - produces a thick, yellowish secretion
• seminal vesicle - produces fructose, vitamin C, prostaglandins
• bulbourethral glands - pea sized and produces a thick clear mucus
• bulbourethral glands - serves as a lubricant during sexual intercourse
• semen - mixture of sperm and accessory gland secretions
• emission - the discharge of semen from urethra
• ejaculation - the forceful explosion of semen from urethra
• scrotum - divided sac of skin outside the abdomen
• scrotum - maintain 3 degree celsius lower to protect sperm viability
• penis - delivers sperm into the female reproductive tract
• regions of the penis: shaft, glans penis ( enlarged tip ) and prepuce ( foreskin )
• vas deferens - form the passageway of the sperm cells
• ejaculation - forceful expulsion of semen
• epididymis - store sperm cells
