Ovarian atrophy is the shrinking of the ovaries, characterized by reduced size and weight, and a decrease in the number of eggs (oocytes), developing follicles, and corpora lutea. This process is a natural part of aging, occurring around menopause, but can also be caused by certain medications or chemical exposures that disrupt the ovaries' normal function.
Understanding Ovarian Atrophy
Ovarian atrophy signifies a decline in ovarian function. The ovaries, crucial for female reproduction, produce eggs and hormones like estrogen and progesterone. As the ovaries atrophy, their ability to perform these functions diminishes.

Age-related atrophy: This is the most common cause, typically occurring with the onset of menopause. As women age, their ovarian reserve (the number of remaining eggs) depletes, leading to a reduction in ovarian size and activity. [Source: Atrophy of the ovary | MyPathologyReport.ca]

Medication and chemical exposure: Certain drugs and environmental chemicals can interfere with ovarian function, accelerating atrophy. These disrupt the hormonal control of ovarian development. [Source: Ovary - Atrophy - Nonneoplastic Lesion Atlas]

Primary Ovarian Insufficiency (POI): Also known as premature ovarian failure, POI is a condition where the ovaries cease functioning normally before age 40. This can result in ovarian atrophy and associated symptoms like irregular periods or infertility.

Symptoms and Diagnosis
The symptoms of ovarian atrophy often mirror those of menopause, including irregular or absent periods, hot flashes, vaginal dryness, and decreased libido. Diagnosis typically involves a physical exam, blood tests (to measure hormone levels), and sometimes imaging studies (ultrasound) to assess ovarian size and structure.
Treatment
Treatment for ovarian atrophy depends on the underlying cause and the severity of symptoms. Hormone replacement therapy (HRT) is often used to manage menopausal symptoms associated with age-related atrophy. For POI, management strategies vary depending on individual needs and goals.
