    ABSTRACT: We report a case of a twin ectopic pregnancy (EP) after in vitro fertilization and embryo transfer (IVF-ET). A 24-year-old nulligravida presented with lower abdominal pain and vaginal bleeding 4 weeks after embryo transfer. Serum beta-HCG levels were 40 IU/mL, 90 IU/mL, and 1970 IU/mL on ET days 12, 14, and 23, respectively. Ultrasound examination revealed two ectopic gestational sacs with fetal heart beats in the left adnexa, without evidence of intrauterine pregnancy. At laparoscopy, one isthmic and another ampullary sac were detected in the left tube and left salpingectomy was performed. The patient was discharged healthy on postoperative day 2. Albeit extremely rare, ectopic pregnancies with abnormal presentation can be encountered following IVF-ET. Single embryo transfer may be advised to protect from ectopic pregnancies after IVF-ET.

    ABSTRACT: To report two successful antagonist IVF cycles; one ending up with pregnancy despite premature luteinization (case 1, aged 35 years), and the other with the retrieval of high quality oocytes despite premature ovulation (case 2, aged 39 years). Serum LH was 36 and 47 IU/L on cycle day 7 before antagonist administration, which was then brought to 6.94 and 3.92 IU/L by antagonist administration, and kept below these levels throughout the remaining stimulation in case 1 and 2 respectively. Serum progesterone was 1.42 and 5.5 ng/mL on the day of hCG respectively. Ten metaphase II (MII) oocytes were harvested wherein 3 grade A embryos were transferred in case 1, and seven good quality MII oocytes were retrieved wherein six embryos were cryopreserved in case 2. More precise cut thresholds for both LH and progesterone are necessary for accurate prediction of the cycle outcomes.
