Clinical pregnancy resulting from intracytoplasmic sperm injection of prematurely ovulated oocytes retrieved from the posterior cul-de-sac.

Objective: To report a clinical pregnancy resulting from intracytoplasmic sperm injection of prematurely ovulated oocytes retrieved from the posterior cul-de-sac.

Design: Case report.

Setting: Academic center.

Determining the optimal follicle size at trigger in patients undergoing ovarian stimulation with a clomiphene citrate plus gonadotropin and GnRH antagonist protocol for in-vitro fertilization.

Background: The aim of this paper was to determine the optimal follicle size at trigger in clomiphene citrate-based in vitro fertilization (IVF) protocols.

Methods: This is a retrospective cohort study performed in at a single academic institution that included first IVF cycles with clomiphene citrate-based protocols at our center between 01/01/2013 and 03/31/2019. Patients were dichotomized by whether they had ≥2 follicles >20 mm on trigger day.

Combined transvaginal and transabdominal oocyte retrieval in a patient with an ectopic ovary and unicornuate uterus.

Objective: To report the utility of combined transvaginal and transabdominal oocyte retrieval in a patient with an ectopic ovary and unicornuate uterus.

Design: Video case report with demonstration of oocyte retrieval technique.

Setting(s): University-affiliated fertility center.

Tubal Ectopic Pregnancy with Undetectable Initial Serum β-Human Chorionic Gonadotropin Level.

We present a case of a tubal ectopic pregnancy (EP) in a patient with an initially undetectable serum β-human chorionic gonadotropin (β-hCG) level. A 33-year-old woman in a same-sex relationship underwent timed donor intrauterine insemination. Her serum β-hCG level was <5 mIU/mL 14 days after the intrauterine insemination.

Fertility preservation with random-start controlled ovarian stimulation and embryo cryopreservation for early pregnancy-associated breast cancer.

We report a case of fertility preservation using random-start controlled ovarian stimulation (COS), intracytoplasmic sperm injection (ICSI) and embryo cryopreservation in a patient with early pregnancy-associated breast cancer. A 34-year-old nulliparous woman at 5 weeks of gestation was diagnosed with estrogen receptor (ER) positive, progesterone receptor (PR) positive and human epidermal growth factor receptor-2 (HER-2) negative infiltrating intraductal carcinoma. Urgent neoadjuvant chemotherapy was deemed necessary and the patient decided to terminate the pregnancy.
