Brief summary

The aim of the work is compare artificial endometrial preparation by oestrogen and progesterone versus pretreatment with Gonadotrophin-releasing hormone agonist (GnRha), oestrogen and progesterone for cryo embryo transfer according to clinical pregnancy rate.

Interventions

Group B (intervention group): Patient will be treated with the GnRh-analouge, triptorelin 0.1mg/day subcutaneously beginning in the mid luteal phase of the previous menstrual cycle and continuing till the date of embryo transfer. Full pituitary desensitization will be ensured by measuring serum estradiol on the first day of the menstrual cycle and should be less than 50 picogram /dl Endometrial preparation will begin from third day of menstruation by oral Estradiol valerate 8mg/day till en
