This case reports the first twin live births achieved in a woman with a serum FSH of such magnitude -80 IU/L, after following early hCG administration in natural cycle in vitro fertilization (IVF). Case report. A 27-year-old with 2 years of primary infertility presented with regular menses since menarche. FSH following clomiphene citrate challenge test was 80 IU/L. Antral follicle count was 1. After failing two IVF cycles, natural cycle IVF with early hCG administration was attempted. Ovulation with 10,000 IU hCG was triggered when the dominant follicle was 10 mm in mean diameter. Two smaller follicles were also present. Oocyte collection was performed 38 h after hCG injection. Three mature oocytes were retrieved. Two oocytes fertilized normally. Two good-quality embryos were transferred on day 2. Bichorionic biamniotic pregnancy was achieved and healthy twins were delivered at term. This case suggests that natural cycles with early hCG administration should be investigated further as an option for poor responders to retrieve more than one mature oocyte, and prevent premature ovulation. We believe this case to represent the patient with the highest serum FSH level, reflective of ovarian reserve at the time of treatment, to achieve a live birth. It is also the first case report to describe this modification on the traditional natural cycle.
