简要总结
Until now no scientific clinical evidence exists regarding the possible impact of long term endogenous androgen priming in IVF patients aligned with the Bologna Criteria, in specific the impact of priming on serum parameters correlated with the ovarian reserve, antral follicle count, and the number of retrievable follicles. Thus, this pilot-study will explore a new suggested protocol for the Bologna criteria patient developed from basic physiology, and will if successful result in a subsequent randomized controlled trial in the same subset of patients, enabling a possible paradigm shift in the treatment of poor ovarian response (POR).
详细描述
A single center study pilot study in 30 IVF Bologna criteria POR patients. All patients fulfilling the ESHRE Bologna criteria will be eligible for inclusion.
Eight weeks prior to stimulation for IVF, patients will start treatment with a low dose of rhCG (Ovitrelle). At the same time daily treatment with the aromatase inhibitor daily will commence, concomitantly with GnRHa down-regulation with a depot GnRHa.
After 8 weeks, stimulation will be performed with a fixed dose of 300 IU rFSH (Gonal F, Merck) for the first 5 days in patients ≤ 34 years of age and 300 IU Pergoveris (Merck) in patients ≥ 35 years of age. The use of hCG and aromatase inhibitor will stop on the first day of stimulation.
Monitoring will be performed according to the standard procedure of the clinic. Patients will receive a bolus of 6.500 IU rhCG (Ovitrelle, Merck) for triggering of final oocyte maturation. Oocyte pick-up and embryo transfer will be performed according to the policy of the clinic. Oocyte pick-up (OPU) and embryo transfer will be performed according to standard procedures.

研究组 & 干预措施
Androgen priming
Eight weeks prior to stimulation for IVF - at the onset of menses, patients will start treatment with a low dose of rhCG (Ovitrelle). At the same time daily treatment with the aromatase inhibitor will commence, concomitantly with GnRHa down-regulation with a depot GnRHa (28days). After 8 weeks, a standard rFSH stimulation with either 300 IU rFSH or 300 IU rFSH+rLH will start. The androgen priming (hCG and aromatase inhibitor) will stop on the first day of stimulation.
干预措施: Androgen priming (Drug)
