Description
Inclusion Criteria:
- Patient selection is based on the ESHRE consensus group 2011 definition of poor ovarian response (POR) (Bologna criteria):
At least two of the following three features must be present:
- Advanced maternal age (≥40 years) or any other risk factor for POR;
- A previous POR (≤3 oocytes with a conventional stimulation protocol);
- An abnormal ovarian reserve test (i.e. Antral follicle count (AFC) <5-7 follicles or Antimullerian hormone (AMH) <0.5-1.1 ng/ml).
Two episodes of POR after maximal stimulation are sufficient to define a patient as poor responder in the absence of advanced maternal age or abnormal Ovarian reserve test (ORT). By definition, the term POR refers to the ovarian response and, therefore, one stimulated cycle is considered essential for the diagnosis of POR. However, patients over 40 years of age with an abnormal ORT may be classified as poor responders since both advanced age and an abnormal ORT may indicate reduced ovarian reserve and act as a surrogate of ovarian stimulation cycle. In this case, the patients should be more properly defined as expected PORs.
Exclusion Criteria:
- Women with endometriosis, endocrinal problems, uterine abnormalities as well as male azospermia.

Intervention / Treatment |
---|---|
Active Comparator: Antagonist
Antagonist protocol (fixed) for IVF/ICSI, with starting dose of human menopausal gonadotrophins (HMG) from 300-450 IU from day 1 of the cycle, antagonist start from day 6 stimulation. Follow-up by ultrasound and serum estradiol will be done. Triggering of ovulation using human chorionic gonadotrophin (HCG) 10000 IU I.M. when at least 2-3 follicles reach 17mm in diameter. Cryopreservation of all embryos at will be done. Frozen embryo transfer in the following cycle will be attempted using estradiol valerate (6mg) for endometrial preparation after pituitary down regulation using long acting GnRH analogue . A maximum of 3 good quality embryos will be transferred. |
controlled ovarian hyperstimulation with various protocols, follow up till stimulated follicles measure from 18-20 mm, then ovum pickup followed by embryo transfer is done.
|
Active Comparator: Short
Short protocol for IVF/ICSI, gonadotrophin releasing hormone analogue (GnRHa) starts from day 1 of the cycle, HMG starts in a dose from 300-450 IU from day 3, Follow-up by ultrasound and serum estradiol will be done. Triggering of ovulation using human chorionic gonadotrophin (HCG) 10000 IU I.M. when at least 2-3 follicles reach 17mm in diameter. Cryopreservation of all embryos at will be done. Frozen embryo transfer in the following cycle will be attempted using estradiol valerate (6mg) for endometrial preparation after pituitary down regulation using long acting GnRH analogue . A maximum of 3 good quality embryos will be transferred. |
