Causes in man

An unfulfilled fertility can occur in both women and men. There are many reasons why a man may have difficulty achieving pregnancy. Here are some of the most common causes:

1. Low sperm count: Low sperm count is one of the most common causes of infertility in men. A sperm count below 15 million sperm per milliliter of semen is considered low and can significantly reduce the chances of pregnancy.
2. Abnormally shaped or motile sperm: Abnormally shaped or moving sperm can also affect fertility. If the sperm are abnormally shaped or do not move fast enough, they may have difficulty reaching and fertilizing the egg.
3. Hormonal disorders: Hormonal disorders such as low testosterone levels or an overactive thyroid gland can also affect fertility by interfering with sperm flow or production.
4. Varicocele: Varicocele is an enlargement of the veins in the scrotum that can affect blood flow and temperature in the scrotum. This can affect sperm production and reduce the chances of pregnancy.
5. Diseases and injuries: Diseases such as diabetes, high blood pressure or injuries to the testicles or prostate can also affect fertility.

There are many other factors that can affect fertility, such as smoking, alcohol and drug use, or certain medications. If a man is having difficulty achieving pregnancy, it is important to talk to a doctor to determine the cause and find appropriate treatment. In many cases, lifestyle changes, medications, or fertility treatments such as in vitro fertilization (IVF) can help improve the chances of pregnancy. With support and medical help, many couples can achieve their dream of having a family.
