Causes of infertility
The causes of infertility vary from person to person.
Infertility is described as the inability to conceive even after 12 months of regular unprotected intercourse without contraception. About 20% of cases of infertility are due to a problem in men, while about 40 to 50% of infertility cases are caused by a problem in women and about 30 to 40% of infertility cases are due to problems in men and women. In most cases, our current lifestyle is considered the leading cause of infertility. Stress is one of the leading causes of infertility in women.
Sperm problems will contribute to about 40% of infertility cases. The normal function of the male reproductive system is first to produce a sufficient number of functional spermatozoa and then to deliver these spermatozoa to the ejaculate. Sperm analysis, which primarily evaluates sperm count, sperm movement, and sperm shape, is a key component in the diagnosis of male infertility.
The dysfunction of the female reproductive organs is also apparent in about 40% of infertile couples. The most common identifiable causes of female fertility problems are described below:
Ovulatory dysfunction (or anovulation) where an egg is not released from the ovary each month is the most common cause of female infertility. Predominant anovulation is caused by hormonal imbalances such as polycystic ovary syndrome (PCOS), but ovarian scarring and premature menopause may also result in an absence of ovulation.
Tubal disease, which includes minor adhesions to complete blockage of the fallopian tubes, prevents fertilized eggs from reaching the site from fertilization to the uterus. It can also prevent sperm from reaching the egg. Normal uterine implantation can not occur. The main causes of tubal infertility are pelvic infections caused by bacteria such as chlamydia, abdominal disease or previous surgery and ectopic pregnancy.
Main causes of infertility in men and women
The most common causes of infertility are detailed below.
Infertility can be caused by various diseases and medical conditions and one in six couples have some form of infertility during their reproductive life.
1. High alcohol consumption affects both sperm production and ovulation, increasing the risk of infertility.
2. Smoking reduces the chances of a couple to conceive. Men who smoke cigarettes usually have low sperm counts and low sperm motility. Women who smoke may suffer from decreased ovarian reserve and chromosomal abnormalities.
3. In men, stress reduces the number of spermatozoa and, in girls, the rules can be irregular.
3. Excessive weight decreases the risk of pregnancy and at the same time increases the risk of developing abnormal spermatozoa in men.
5. Sexually transmitted diseases such as chlamydia and gonorrhea can affect male and female fertility. They can seriously damage the woman’s reproductive system and inflamed the scrotum in humans.
