• The scrotum i also sometimes called the scrotal sac. The scrotum holds and protects the testicles, which are where sperm are produced
• Testicles when the testicles are about 6 degrees cooler than normal body temperature, they will successfully produce sperm.
• When a boy reaches puberty, special coiled tubes inside the testicles begin to make sperm cells. From this point on, the testicles continue producing sperm for the rest of male's life at the rate of hundreads of million each day
• The epididymis is along, coiled tube about 20 ft long that sits on the top of and behind each testicle

• The mitochondria supplies the energy for the tail to move. The tail moves back and forth tom propel the sperm towards the egg
• Semen i also called as seminal fluid. It contains nutrients that will make the sperm alive and provide energy while they race to the egg. The main source of energy is fructose
• The function of female reproductive system 1.Produces female sex cells 2.Produces female reproductive hormones 3.Receives sperm cells from the male 4.Nutures the development and provides nourishment for the new
• Vagina it is a muscular, hallow tube that is about 7cm to 20cm long in an adult female
• The vagina can expand and contract. Its ability to become wider or narrower allows the vagina to accommodate something as slim as a tampon or as wide as a baby
