Primary infertility occurs in couples who can not produce a pregnancy after at least a year have sex without contraception. Second infertility describes couples who had previously been pregnant at least once, but can not get pregnant again after that.

The reasons vary. Can be due to physical or emotional factors. Nearly 30-40% of all infertility is due to the factor of 'man' like, poor ejaculation, impotence, decrease in hormones, environmental pollution, injuries sexually transmitted disease, or decreased sperm count.

Infertility because of 'woman' as, blood sexually transmitted disease or endometriosis, ovulation dysfunction, lack of nutrition, hormone imbalance, cysts in the uterus, pelvic infection, tumor, or a transportation system that is not normal from the cervix to the fallopian tubes - also affects 40 -50% of infertility couples.

Compounded by a factor of age, increased risk of infertility in men associated with the things below:

• Sexual partners more than one (increasing the risk of contracting sexually transmitted diseases)
• Contracting sexually transmitted diseases
• Has a history of orchitis or epididymitis disease
• Mumps
• Varicocele
• Past medical history that includes DES exposure (men or women)
• Long-term chronic illnesses such as diabetes.

Symptoms:

• Inability to produce sperm that can survive.
• Emotional reaction at arm's length from one or both partners. Usually, several reactions become great among couples childish. Having at least one child would alleviate some of this emotion.

PREVENTION
Because infertility is usually caused by sexually transmitted diseases, sexual intercourse is safe to minimize the risk of possible infertility in the future. Gonorrhea and chlamydia are the two main causes of infertility.

Initially infertility often has no symptoms until the disease signs appeared, such as salpingitis. This inflammatory process causes the fallopian tube channels wound and reduce fertility, infertility is uncertain, or the increasing emergence of a pregnancy outside the uterus.

Mumps immunization has been shown both to prevent goiter and complications in men, ie orchitis. Immunization prevents mumps, which is also associated with fertility.

Some forms of contraception, such as intrauterine devices (IUD), carry a high risk of infertility in the future. However, the IUD is not recommended for women who had never had children before.

Early diagnosis and treatment of endometriosis may reduce the risk of infertility.
