title: Human chorionic gonadotrophin self-administered by the subcutaneous route to induce oocyte maturation in an in-vitro fertilization and embryo transfer programme.
abstract: This study was initiated to evaluate oocyte maturation and the outcome of in-vitro fertilization (IVF) cycles following the s.c. administration of human chorionic gonadotrophin (HCG) by the patient herself or her partner. A group of 104 women who entered our IVF embryo transfer programme were prospectively randomized to have 5000 IU or 10,000 IU HCG s.c. or i.m. The HCG was administered for induction of the final oocyte maturation in cycles with pituitary down-regulation with a gonadotrophin-releasing hormone agonist according to a long protocol and where ovarian stimulation had been achieved with pure follicle stimulating hormone. The mean concentration of HCG in serum 12 and 36 h after the HCG injection was significantly higher in the women receiving 5000 IU i.m. compared to the s.c. route. However, in women receiving 10,000 IU HCG there were no significant differences in the mean concentrations 12 and 36 h after the injection, irrespective of the route of administration. Furthermore, there were no significant differences in the relative numbers of retrieved mature oocytes between the groups. When comparing the clinical outcome in the different groups, no significant differences were found between those receiving 5000 IU or 10,000 IU HCG, i.m. or s.c. Our data indicate that HCG can be given s.c. without reducing the chance of retrieving a mature oocyte and that the clinical outcome with regard to pregnancies is not negatively affected.
