Patient: Description (onset, main symptoms, hospital visited, etc.): A cyst was found in the left ovary at the beginning of 2009, and a small fibroid was found in the uterus, and the size of the cyst has not changed since 2009. I have been having normal periods and no pain during menstruation, no adverse reactions. My husband’s sperm test was normal. In July, August and September 2010, I had ovulation monitoring for three months, all of which were normal ovulation on the right side, but still no pregnancy. The results of the monitoring in August are as follows: Day 14 of the first monitoring: the uterus is posterior, size 51×46×50MM, clear outline, a hypoechoic area is visible in the myometrium of the anterior uterine wall, size 17×7MM, clear border, uniform internal echogenicity. The left ovary was 48×32×41MM in size, with 4 follicles, the largest being 7×6MM, and a cystic echogenicity was seen in the left ovary, 34×25MM in size, with a thick wall, poorly transmissive, and fine light spots. The right ovary was 39×29×28MM, with 6 follicles, the largest of which was 15×10MM. On day 20, the endometrial thickness was 11.7MM, and the largest follicle on the right ovary was 20×18MM. On day 22, the endometrial thickness was 12.9MM, and the right ovary was humming in size, with no mature follicles seen as described previously. Luteinizing hormone 4.21 (reference value 2.12~10.89), follicle stimulating hormone 6.7 (reference value 3.85~8.78), prolactin 14.25 (reference value 3.34~26.72) 22), progesterone 1.57 (reference value 0.31~1.52) Estradiol This is a little lower 15.5 (reference value (27~ 122), testosterone 0.49 (reference value 0~0.75). But since I am 31 years old, now my doctor said that the cyst should be a chocolate cyst (but I have normal periods and no pain) and it is better to have a laparoscopy first to look directly at the pelvis, fallopian tubes and then remove the cyst. I would like to ask the doctor, can I be sure that the ovarian cyst in my case is a chocolate cyst? Do I need to do other tests like tubal examination first and then laparoscopic surgery if it is really not working. I think I have ovulation on my right side, so if my tubes are open, can I get pregnant? My doctor told me to think about it myself and I would like to ask for your advice? Are there any disadvantages to laparoscopy? I look forward to your reply, thank you! Yuan Songhua: The doctor has a point in this case. From the ultrasound description, there is a high possibility of chocolate cysts, which can affect pregnancy in some patients. The purpose of the surgery is to know clearly the condition of your pelvis, whether there is obstruction in the fallopian tubes, and if there are coarctation or endometriosis, the cyst can be removed at the same time, but the premise of the surgery is to protect the function of the ovaries (which is related to the operation of the surgeon).
