Male Reproductive System
Male Reproductive System
There are three major purposes of the male reproductive system: production of spermatozoa, secretion of sex hormones and to transport spermatozoa from male to the female. The organs in this system are mainly external and consist of a penis and the scrotum, which contains and protects testes. Because the testes require lower temperature than the rest of the body, the scrotum regulates temperature for normal spermatozoa development. When the testes need to cool down, the cremaster muscle relaxes and allows them to hang further from the body; however when the warmth or protection is required, the muscle contract to pull testes closer. (Rogers, 2011)
The main purpose of the testes is to produce spermatozoa and testosterone. …show more content…
During sexual arousal erectile tissue fills up with blood due to nerve impulses. The semen is then expelled by urethra through the shaft of the penis to the outside of the body. This is achieved by muscle contractions as a result of stimulation to the sympathetic nerves of the epididymis, prostate, vas deferens and seminal vesicles. Once ejaculated, the maximum life span of spermatozoa is 24 to 72 hours at body temperature. (Rhoades and Pflanzer, 1996)
Female reproductive system
The main functions of the female reproductive system are the secretion of oestrogen and progesterone, production of ova, gestation and delivery of the foetus. The secretion of sex hormones and production of ova functions are carried out by the ovary. The gestation and delivery are performed by the uterus and cervical canal. See diagram …show more content…
Method Benefits Risk Effective
