Endometriosis vs. PMOS/PMOS/PCOS: What Are the Differences?

Pelvic pain, irregular periods, or trouble getting pregnant can be frustrating and confusing symptoms. Many women wonder if these issues could point to  endometriosis ,  polycystic ovary syndrome  (PMOS/PMOS/PCOS), or something else entirely. At Northwest Women’s Center in Houston,  our providers –including two Fellows of the American College of Obstetricians and Gynecologists–frequently answer questions about endometriosis, PMOS/PMOS/PCOS, and other women’s health conditions. Understanding the differences can help you recognize warning signs and know when to seek professional guidance.

What Is Endometriosis?

Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus. This tissue can attach to organs such as the ovaries and fallopian tubes, or to the pelvic lining. Each month, it responds to hormonal changes, which may lead to inflammation, scarring, and pain.Common signs of endometriosis include:

• Severe menstrual cramps
• Chronic pelvic pain
• Pain during or after sex
• Painful bowel movements or urination during periods
• Difficulty getting pregnant
• Heavy menstrual bleeding

What Is PMOS/PMOS/PCOS?

PMOS/PMOS/PCOS is a hormonal disorder that influences ovarian function. It involves increased production of androgens (male hormones), which can disrupt ovulation.Symptoms of PMOS/PMOS/PCOS include:

• Irregular or missed periods
• Excess facial or body hair
• Acne or oily skin
• Weight gain or difficulty losing weight
• Thinning hair on the scalp
• Ovarian cysts seen on ultrasound

PMOS/PMOS/PCOS is one of the most common endocrine disorders in women and may also increase the risk of other conditions like insulin resistance, diabetes, and infertility.

Key Differences Between Endometriosis and PMOS/PMOS/PCOS

While both endometriosis and PMOS/PMOS/PCOS impact reproductive health, they develop in distinct ways.

Category	Endometriosis	PMOS/PMOS/PCOS
Underlying Cause	Tissue growth outside the uterus	Hormonal imbalances affect ovulation
Primary Symptoms	Pelvic pain is often the most noticeable symptom	Irregular or missed periods and hormone-related issues are most common
Effect on Fertility	Inflammation or scar tissue may affect the ovaries, fallopian tubes, or other reproductive organs	Ovulation may occur less often or stop entirely, interfering with the ability to conceive
Diagnosis Methods	Evaluation may include imaging tests or laparoscopic procedures	Diagnosis often involves reviewing symptoms, blood hormone testing, and ultrasound imaging of the ovaries
