Endometriosis Symptoms and Causes

At Fertility & Surgical Associates of California (FSAC), we know how confusing, painful, and isolating endometriosis can feel. If you live near Thousand Oaks, Encino, or Santa Monica, California, please know this—you’re not alone, and your symptoms are real.

Endometriosis affects millions of people around the world, often silently. For some, it’s years of discomfort before a diagnosis finally brings answers. For others, it’s a daily balancing act of managing pain and maintaining hope for the future. Wherever you are in your journey, we’re here to help you understand what’s happening inside your body and take the next step toward relief and healing.

What Exactly Is Endometriosis?

Endometriosis happens when tissue similar to the lining of the uterus grows outside of it—often on the ovaries, fallopian tubes, or pelvic surfaces. In rare cases, it can appear beyond the pelvic area.

Each month, this misplaced tissue responds to hormonal changes, thickening and breaking down just like the uterine lining. The difference is, it has nowhere to go. Over time, that can cause inflammation, scar tissue, painful cysts, and adhesions that may pull on nearby organs.

Endometriosis can affect anyone with a uterus during their reproductive years. According to the World Health Organization, around 10% of people of reproductive age are living with it—and many may also face fertility challenges along the way.*

If you suspect something isn’t right, trust that instinct. Your symptoms deserve attention and compassion, not dismissal.

Listening to Your Body: Common Signs of Endometriosis

Endometriosis doesn’t always look the same from one person to another. Painful periods are a hallmark sign, but many experience other symptoms that are often overlooked. You might notice:

Severe menstrual cramps or chronic pelvic pain
Pain during or after sex
Spotting or bleeding between periods
Digestive issues that seem tied to your cycle
Struggles with infertility

Every body tells a different story. Some people with extensive endometriosis feel little pain, while others with a small amount of tissue growth experience significant discomfort. That’s why individualized care—and a provider who truly listens—matters so much.

Why Does Endometriosis Happen?

The exact cause of endometriosis is still being studied, but several factors may play a role:

Retrograde Menstruation: When menstrual blood flows backward into the pelvic cavity.
Immune System Response: When the body doesn’t recognize and clear away misplaced tissue.
Genetics: A family history of endometriosis may increase your risk.
Hormonal and Developmental Factors: Estrogen is known to influence the growth of this tissue.

There’s currently no way to prevent endometriosis—but early diagnosis and expert care can make a life-changing difference. Our reproductive endocrinologists work closely with you to manage symptoms, support your fertility, and help you regain control over your health.
