In vitro Fertilization of in vitro Matured Oocytes Obtained from the Follicles without hCG Exposure for Prevention of Severe Ovarian Hyperstimulation Syndrome: A Case Report
1996
We aspirated ovarian follicles of an infertile patient who encountered a great risk of ovarian hyperstimulation (OHSS) during her ovulation-induction cycle, which had been stimulated with gonadotropins, in order to avoid OHSS without interrupting the treatment. If this action were to yield a considerable number of immature oocytes, some of which were to achieve in vitro maturation and subsequent fertilization, this method could be an alternative to conventional ovulation-induction methods for patients who repeatedly present imminent signs of hyperstimulation. However, the number of oocytes collected from the patient was disappointingly low, even though a large number of follicles were thoroughly aspirated. One of these oocytes was matured in vitro in a medium containing 30% follicular fluid and granulosa cells of mature follicles, fertilized, cryopreserved, and transferred in a later artificial cycle; but pregnancy was not achieved. A low number of recovered oocytes from patients in this situation might be a factor that greatly limits the clinical applications of this method.
