What Are the Causes of Luteal Phase Defects?

A luteal phase defect can come through a significant issue in the follicular stage. Due to the defect, the number and quality of follicles remain underdeveloped per their need. The follicle eventually becomes corpus luteum and affects the amount of progesterone. A person having this defect may have a short luteal phase. Other causes are given as follows:

Smoking: As per a study, smoking reduces the body’s ability to produce progesterone. This can lead to a defect.

Endometriosis: A condition where a tissue similar to the lining of the uterus grows on other parts of the body.

Polycystic Ovary Syndrome (PCOS): This syndrome causes irregular menstrual periods, excess hair growth, acne, and infertility.

Obesity: A chronic disease that leads to excessive body fat. It is also a leading cause of poor health.

Eating disorders: Anorexia and other such eating disorders too are a cause of a luteal phase defect.

Thyroid conditions: Diseases where the thyroid gland does not make the right amount of hormones. Hypothyroidism and hyperthyroidism are the two types of thyroid disease.

Pituitary gland disorders: This gland is located at the base of your brain. The pea-sized endocrine gland releases important hormones and controls the function of other endocrine glands. Any disorder related to it can be life-threatening.

Stress and Excessive Exercise: Stress and excessive amounts of exercise are also the leading causes of a luteal phase defect.
