Erectile dysfunction, sexually transmitted diseases, smoking and stress have an overwhelming influence on reproduction. According to statistics, 18% of couples worldwide are infertile, and in about half of them male infertility is the main cause. The causes of infertility in men are varied and manifold. Some of these causes can be corrected and may overcome this problem. Here’s a rundown of the most common problems that may underlie a male infertility.

Smoking and drinking

According to experts, men who smoke experience a decrease in testosterone levels by 35%. By default, disrupting hormonal balance negatively affects fertility. Also toxic substances in cigarette affect the quality and sperm motility. The higher the number of cigarettes smoked, the greater are the fertility issues. Alcohol is equally as harmful as smoking. It has been observed that people who consume too much alcohol have a low testosterone level, low secretion of sperm and therefore suffer from erectile dysfunction. Erectile dysfunctions can be treated with medication. However, consider opting for a natural erectile pill, such as Vigrx. Vigrx uses herbal ingredients and no synthetic substances. It promises to help erections last for longer by improving blood flow.

Immunological infertility

The organism can develop an immune response (antibodies) to its own sperm. The causes may be trauma or testicular infection, large varicoceles or testicular surgery. Sometimes the reasons can not be determinate. These antibodies have a negative effect on fertility although the exact reason still remains unclear. Most likely, the antibodies act negatively at several points along the pathway to fertilization. They slow sperm to penetrate the partner’s cervical mucous and make its way to the uterus. It also slows sperm from joining zonapellucida (outer membrane of the egg). Antibodies also hinder sperm to fuse with the membrane of oocytes (eggs).

Genetic factors

Genetic anomalies can be both inherited and acquired during life (through interaction with the environment), and some may even occur during in vitro fertilization procedures (artificial). Seeding egg with incompatible sperm is one of the risks associated with assisted reproductive technologies, and one of the big differences compared with natural conception (during natural process, a sperm with genetic changes would not be able to reach and penetrate the egg).
If the genetic material of the sperm shows multiple fragmentation of DNA or chromosomal irregularities, the man will be infertile because these sperm are not viable and can not take active part in the process of conception.

Genetic transmitted disease

There are genetic diseases transmitted that can adversely affect fertility. These include:
Cystic fibrosis: is a hereditary disease that affects the exocrine and endocrine glands in which the reproductive system is characterized by bilateral absence of the vas deferens (responsible for the carrying the sperm).
Patients suffering from Klinefelter will have a wide spectrum of signs and symptoms and are at increased risk of developing cell tumors, osteoporosis, diabetes or rheumatoid arthritis.
Polycystic kidney: is a genetic disease of the kidneys that is progressive and is characterized by the presence of multiple cysts in both kidneys, but also in the liver, pancreas and rarely in the heart and brain. If the cysts appear and develop in the reproductive tract, the patient will be infertile (this can be the first sign of illness).
