The aim of this work is to study the value of GnRH antagonist subcutaneous administration as an alternative to coasting in prevention of severe OHSS and its impact on embryos quality \& the outcome of ICSI.
Infertility affects up to one in seven couples all over the world. In vitro fertilization-embryo transfer (IVF-ET) and intracytoplasmic sperm injection (ICSI) are commonly used in the management of infertility attributable to tubal factor, significant endometriosis, male factor and also persistent unexplained infertility. Recruitment and development of multiple follicles in response to gonadotrophin stimulation are necessary for successful assisted reproduction. In young ovulating women undergoing IVF treatment, the standard stimulation protocol can result in either poor response or ovarian hyperstimulation syndrome (OHSS).
OHSS is a serious and potentially life-threatening iatrogenic complication of controlled ovarian hyperstimulation (COH) which may cause serious impact on patient's health. OHSS is the most feared complication of IVF-related ovarian stimulation, which in its severe form leads to hospitalization and in the worst case scenario fatal complications. As many as 33% of IVF cycles have been reported to be associated with mild forms of OHSS. The incidence of moderate OHSS is estimated to be between 3% and 6%, while the severe form may occur in 0.1-3% of all cycles. Among high risk women the incidence approaches 20%.
Development of multiple follicles forms the basis of OHSS. Exogenous human chorionic gonadotrophin (hCG) administration for the final maturation of oocytes or endogenous production of hCG after pregnancy is the second factor needed for the development of severe OHSS. Severe OHSS is characterized by massive ovarian enlargement, pleural effusion, ascites, oliguria, hemoconcentration, and thromboembolic phenomena. Coasting is described as a withholding therapy while continuing with releasing hormone agonist/antagonist administration, until safe levels of estradiol (E2) are attained. GnRH antagonists causes an immediate suppression of E2 levels and therefore could prevent OHSS in GnRH antagonist cycles. A comparison between coasting and GnRH antagonist administration in women at high risk of OHSS during ovarian stimulation for IVF with GnRH agonist long protocol, in the hope of preventing the drawbacks of prolonged coasting.
| Arm | Type | Interventions | Description |
|---|---|---|---|
| Coasting group | Experimental | Drug: Gonadotropin | Including 150 patients who will undergo withholding gonadotropin administration for at least 24 hours before triggering ovulation with hCG. GnRH agonist will be continued daily till the day of triggering. E2 will be measured daily until the concentration falls to ≤ 3000 pg/ml, then 5000 IU of hCG will be given. |
| Antagonist group | Active comparator | Drug: Antagonist | Including 150 patients who will receive GnRH antagonist (subcutaneous injection Cetrorelix acetate 0.25 mg (Cetrotide, Serono, UK)) daily until the day of hCG administration. GnRH agonist will be discontinued at the start of antagonist administration. E2 will be measured daily until the concentration falls to ≤ 3000 pg/ml and TVS revealed that follicles diameter is ≥ 18 mm, then 5000 IU of hCG will be given. |
