While age is a significant factor in egg quality, there are many other physical issues that can affect the egg quality and production. Identifying these factors can help women take proactive measures to improve their fertility, including visiting a gynaecologist and endocrinologist early.

Irregular periods can be a sign of hormonal imbalance, which can affect egg quality. Women with irregular periods may experience 'anovulation', where the ovaries do not release an egg.

Ovarian cysts

Ovarian cysts can often affect egg quality by causing hormonal imbalances and inflammation in the body.

Weight issues

Being underweight or overweight can affect the quality of eggs. Women with weight issues may experience hormonal imbalances, which can affect ovulation.

Premature ovarian failure (POF)

POF is a condition where the ovaries stop functioning before the age of 40. This can affect egg quality and make it difficult to conceive.

Autoimmune disorders

Autoimmune disorders, such as lupus or rheumatoid arthritis, can affect egg quality by causing inflammation and hormonal imbalances in the body.

Thyroid issues

Thyroid problems, such as hypothyroidism or hyperthyroidism, can affect egg quality, too. Women with thyroid issues may experience irregular periods, fatigue, and weight gain.

Endometriosis

Endometriosis is a condition where the tissues that line the walls of the uterus grow outside of the uterus and make their way to other organs, leading to inflammation and scarring. This can affect egg quality and make it difficult to conceive.
