What are the causes of infertility in men and women?

Infertility is a medical condition that affects many couples worldwide, where they are unable to conceive even after trying for a year or more. It affects women and men both, and in some cases, both partners may have contributing factors.

Understanding the causes of infertility is crucial in treating it. In this blog, we will explore the most common reasons why couples fail to get pregnant.

What causes infertility in men?

Low Sperm Count

Male infertility is most often caused due to low sperm count. This could be a result of various factors such as hormonal imbalances, genetic factors, infections, or exposure to toxins. Certain medications and recreational drugs can also reduce sperm count.

Abnormal Sperm Shape and Size

Sperm abnormalities, such as an unusual shape or size, can affect the motility of the sperm, making it difficult for them to reach and fertilise an egg.

Erectile Dysfunction 

Erectile dysfunction (ED) is a condition in which men have problems achieving or maintaining an erection, leading to difficulties in intercourse.

Varicocele 

When the veins inside the scrotum become enlarged, it is called Varicocele. This leads to reduced blood flow to the testicles, affecting the production of healthy sperm.

Infections

Certain infections, such as sexually transmitted infections (STIs), including gonorrhoea and chlamydia, can cause inflammation of the reproductive system and lead to infertility.

What are the causes of infertility in women? 

Ovulation Disorders

Ovulation disordWhat are the Causes of Infertility in Men and Womeners are one of the most common causes of female infertility. They can be caused by various factors, including hormonal imbalances, polycystic ovary syndrome (PCOS), thyroid disorders, and obesity. Irregular menstrual cycles are a common symptom of ovulation disorders.

Endometriosis

Endometriosis is a serious condition that causes scarring and inflammation. In this condition, the tissue that lines the uterus grows abnormally outside the uterus also. It can affect the ability of the egg to implant in the uterus.

Fallopian Tube Blockage 

Fallopian tube blockage can be caused by various factors such as pelvic inflammatory disease (PID), endometriosis, or surgery. The blockage does not allow the sperm to reach the egg. In other cases, it may allow fertilisation but the fertilised egg fails to reach the uterus.

Age

Age has a significant impact on female fertility. Women over the age of 35 have a higher risk of infertility due to the decline in the quality and quantity of eggs.

Uterine Problems

Uterine problems such as fibroids, polyps, or abnormalities in the uterus shape can interfere with implantation and cause infertility.

Conclusion 

Fertility can be caused due to multiple factors in both men and women. Most causes of infertility can be treated thanks to the many medical advancements in recent times.
