Obesity and fertility

Obesity and fertility is a topic that explores the relationship between body mass index (BMI) and fertility. Obesity, defined as a BMI of 30 or above, can have significant effects on both male and female fertility.

Overview

Obesity can affect fertility by causing hormonal imbalances and problems with ovulation, particularly for obese women. Obesity is also associated with Polycystic ovary syndrome (PCOS), a common cause of infertility. For men, obesity can affect sperm count and motility, and can cause hormonal changes that reduce fertility.

Effects on Female Fertility

Obesity has many effects on female fertility. It can cause hormonal imbalances that affect the menstrual cycle and can lead to reduced fertility. Obesity is also associated with an increased risk of miscarriage and other pregnancy complications.

Ovulation

Obesity can affect ovulation, the process by which the ovaries release an egg each month. This can lead to irregular menstrual cycles and reduced fertility.

Polycystic Ovary Syndrome

Obesity is a major risk factor for PCOS, a condition that affects the ovaries and can cause infertility. Women with PCOS often have insulin resistance, which can be exacerbated by obesity.

Effects on Male Fertility

Obesity can also affect male fertility. It can lead to hormonal changes that reduce sperm count and motility, and can increase the risk of erectile dysfunction.

Sperm Quality

Obesity can affect the quality of a man's sperm, reducing its ability to fertilize an egg. This can lead to reduced fertility.

Treatment

Treatment for obesity-related fertility problems often involves lifestyle changes such as diet and exercise. In some cases, medication or surgery may be recommended.
