Message from the Director, Dr. Muneyyirci-Delale:

Welcome to the Center for Treatment and Study of Endometriosis web site!

I am currently the director of the Division of Reproductive Endocrinology and Infertility with a specialty in diagnosis and treatment of endometriosis. My interest in this topic, for both patient care and research, came from my interest in the manipulation of hormones. Specifically, endometriosis is a debilitating autoimmune disease that is dependent upon the hormone estrogen with no known cure. Patients with serious complications have been referred to me for almost 30 years such as those with advanced and non-operable stages of endometriosis, those who have undergone multiple surgeries but are still experiencing pain, and individuals that are in premature menopause; all of whom I have been able to help to manage and reduce the severity of their endometriosis. Preventing multiple surgeries, complications, and early menopause are the driving forces behind my research. We currently have funding, and are applying for more funding, to study the causes and factors of this disease in order to prevent it. We are currently looking at markers for endometriosis to diagnose and treat endometriosis in its early stages (during teenage years). We are also comparing different treatments for endometriosis. Just recently I have submitted a paper about women who have had recurrent endometriosis (endometriosis cysts) after surgeries. I have been able to shrink the size of the cyst and improve their symptoms.

Please look through our page on information about endometriosis, our staff, current studies we are conducting, and any other information. If you are interested in a consult, feel free to make an appointment.

Female Reproductive Organs

illustration of uterus

The normal female has two ovaries, two fallopian tubes, the uterus, and the vagina. The lining of the uterine cavity is called endometrium. The ovaries produce an egg each month (ovulation) and secrete female hormones (estrogen and progesterone).

What is Endometriosis?

figure 1 figure 2 figure 3

The endometrium is the lining of the uterus. This lining regurgitates into the abdominal cavity during the menstrual period through the fallopian tubes. This endometrial tissue (cells) in response to female hormones (estrogen and progesterone) sometimes grows outside the uterus, usually within the abdominal cavity. It can appear on the ovaries, fallopian tubes, and less commonly in the rectum, vagina, intestines, bladder and elsewhere. The tissue causes cyst formations and adhesions (scar tissue).

Since the tissue continues to respond to reproductive hormones, bleeding can occur from this displaced tissue during the menstrual cycle, causing the symptoms like painful period (cramps), painful sex and pelvic pain. Other symptoms include spotting between periods, abdominal swelling, and diarrhea, blood in the urine or stool and others depending on which organs are involved. Symptoms may vary from woman to woman. The symptoms may resolve with treatment and then return later. They usually disappear after treatment.

Endometriosis is a leading cause of painful periods (dysmenorrhea), chronic pelvic pain and infertility. However, there may be reasons other than endometriosis for why you are feeling pain. Endometriosis is diagnosed by history, examination, ultrasound (sonogram), computed tomography (CT) scan, magnetic resonance imaging (MRI) and laparoscopy. If you have these symptoms you can contact us for diagnosis and treatment.

If you have surgically diagnosed endometriosis, have painful periods, pelvic pain and are not trying to become pregnant within the next two years; please contact us to find out if you are eligible for free treatment, study procedures and visits.

How is endometriosis treated?

The choice of treatment depend upon the severity of the symptoms, location of endometriosis, and if you want to get pregnant.

  1. Surgical treatment.
  2. Medical treatment.
  3. A Combination of surgery and medical treatment.

Research Activities

We are currently recruiting! If you have been diagnosed with endometriosis and interested in free treatment, please give us a call so that we can schedule a meeting or discuss the details further at 718-270-1364 or 718-270-2101. We can also be reached via e-mail at

We are also currently conducting studies on these additional topics:

  1. Endometriosis F11-R and other markers;
  2. Treatment and Study of Primary Dysmenorrhea (period cramps);
  3. Endometrium Urinary Steroids (hormones);
  4. Serum hormones and endometriosis;
  5. Fibroids/Leiomyomas;
  6. PCOS (Polycystic Ovarian Syndrome).

Educational Activities

Dr. Muneyyirci-Delale gives lectures to doctors, residents, medical students, physician assistants, nurse practitioners and lay persons about endometriosis and other topics related to reproductive endocrinology and infertility.

The recent lecture schedule includes:

  • Obstetrics and Gynecology Review Course
  • Endometriosis
  • Dysemenorrhea (painful period : cramps)
  • Uterine Leiomyomata (myoma, fibroid uterus)
  • Dysfunctional Uterine Bleeding (abnormal uterine bleeding)
  • Premenstrual Syndrome (PMS)

Clinical Care

We can help!

We are also committed to helping women who have not been diagnosed with endometriosis but do experience painful period pains. Pelvic pain experienced around one's period or at other times of the month may be the first and most noticeable sign that something may be wrong. We encourage women to see a reproductive endocrinologist to further investigate the source their pelvic pain. To make an appointment to see Dr. Muneyyirci-Delale (Dr. Muney) independent of the research project, about infertility, endometriosis treatment options, or other gynecological issues, feel free to call us at (718) 270-2101.
