Physical examination shows no abnormalities. Which of the following is the most likely cause of this patient's infertility?

Four hours after undergoing an abdominal hysterectomy, a 43-year-old woman is evaluated in the post-anesthesia care unit because she has only had a urine output of 5 mL of blue-tinged urine since surgery. The operation went smoothly and ureter patency was checked via retrograde injection of methylene blue dye mixed with saline through the Foley catheter. She received 2.4 L of crystalloid fluids intraoperatively and urine output was 1.2 L. She had a history of fibroids with painful and heavy menses. She is otherwise healthy. She underwent 2 cesarean sections 8 and 5 years ago, respectively. Her temperature is 37.4°C (99.3°F), pulse is 75/min, respirations are 16/min, and blood pressure is 122/76 mm Hg. She appears comfortable. Cardiopulmonary examination shows no abnormalities. There is a midline surgical incision with clean and dry dressings. Her abdomen is soft and mildly distended in the lower quadrants. Her bladder is slightly palpable. Extremities are warm and well perfused, and capillary refill is brisk. Laboratory studies show: Leukocyte count 8,300/mm3 Hemoglobin 10.3 g/dL Hematocrit 31% Platelet count 250,000/mm3 Serum _Na+ 140 mEq/L _K+ 4.2 mEq/L _HCO3+ 26 mEq/L _Urea nitrogen 26 mg/dL _Creatinine 1.0 mg/dL Urine _Blood 1+ _WBC none _Protein negative _RBC none _RBC casts none A bladder scan shows 250 mL of retained urine. Which of the following is the next best step in the evaluation of this patient?

A 17-year-old female presents to your office expressing concern that despite experiencing monthly pelvic pain for the past few years, she has not yet started her menstrual cycle. She is not taking oral contraceptive therapy and has never been sexually active. On physical exam the patient is of normal stature with appropriate breast development and growth of pubic and underarm hair. The patient declined a vaginal exam. Karyotype analysis reveals she has 46 XX. Pregnancy test is negative, thyroid stimulating hormone, prolactin, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels are normal.

A 32-year-old woman visits her family physician for a routine health check-up. During the consult, she complains about recent-onset constipation, painful defecation, and occasional pain with micturition for the past few months.

She and her husband are trying to conceive a second child, but lately, she has been unable to have sexual intercourse due to pain during sexual intercourse. During the physical examination, she has tenderness in the lower abdomen with no palpable mass. Pelvic examination reveals a left-deviated tender cervix, a tender retroverted uterus, and a left adnexal mass. During the rectovaginal examination, nodules are noted. What is the most likely diagnosis for this patient?
