When body temperature rises, muscles attached to the scrotum relax and go lower, away from the body. If body temperature lowers, muscles tighten and testes move closer to the body.

The scrotum protects sperm by keeping testes slightly below normal body temperature.

Some causes of sterility are: abnormal sperm production or function, genetic defects, some health problems such as diabetes or infections such as chlamydia, gonorrhea, mumps or HIV.

Sterility is the quality or condition (in males) of being sterile- inability to reproduce from either too few sperm or poor quality of sperm.

Mumps can cause male infertility. By taking vaccines, it might help a boy to reproduce in later years.

From teenage to approximately his 20`s, a male has to take care of his reproductive health by doing self-check regularly. When he is in his 30`s or older, he needs to get checked regularly for reproductive system problems. Also, from 14 to 40 years of age, there is a higher chance of getting testicular cancer, while when they get older there is a higher chance of getting prostate cancer.

Younger males- taking care of reproductive system, self-check, higher chance of getting testicular cancer

Older males- proffesional check, higher chance of getting prostate cancer

Sperm is a motile reproductive cell of males with a haploid nucleus. They are carrying the genetic information of males to the egg cell of the female and together they form an embryo. Semen is the seminal liquid which contains the sperm cells and plasma liquid that nourishes sperms and keep them motile.

Sperm is the only cellular component of the semen which is a liquid carrier of sperm.

To maintain their reproductive health, males should do several things. First of all, they should bathe regularly and pay attention to wash their penis, scrotum and area under foreskin properly. If doing sports, they should wear protective equipment to shield the external reproductive organs. Abstinence will help to avoid STD`s. They should also check their scrotum and testicles regularly, once a month, to see if there is a lump. Besides sel-check up`s, they should have regular checkups by a physician every 12 to 18 months.

Bath regularly; wear protective equipment; practice abstinence; perform regular self-examinations; get regular check-ups. See the explanation for details.

Not wearing proper sports gear can be very dangerous. Wearing protective equipment and proper using of it, can reduce the chance of getting injured. Protecting yourself is important no matter which sports you are into. The protective cup shield`s the external reproductive organs. Wearing knee pads helps you avoid arthritis or meniscus injuries and prevents damaging your knee when you fall or when you get kicked. Wearing shoulder pads will help you prevent injuries such as dislocations or shoulder strains.
