Brief summary
The first In-Vitro Fertilization cycles were performed in natural unstimulated cycles. Today gonadotrophins are administered to induce multiple follicular development and controlled ovarian hyperstimulation. During ovarian stimulation gonadotrophin-releasing hormone analogues are co-administered in order to prevent premature luteinizing hormone surges. Premature luteinizing hormone surges are observed in about 20% of stimulated cycles without using gonadotrophin-releasing hormone analogues . Avoiding the adverse effects of elevated luteinizing hormone levels, first gonadotrophin-releasing hormone agonist analogues were used to supplement the gonadotrophin stimulation. The continuous administration of gonadotrophin-releasing hormone agonists causes gonadotrophin suppression through down-regulation and desensitization of the gonadotrophin-releasing hormone receptors in the pituitary gland after an initial short period of gonadotrophin hypersecretion . Gonadotrophin-releasing hormone antagonists (cetrorelix and ganirelix) cause immediate and rapid gonadotrophin suppression by competitive antagonism of the gonadotrophin-releasing hormone receptor in the pituitary without an initial period of gonadotrophin hypersecretion. Several advantageous effects of cetrorelix were established , and these effects seemed to be independent from the type of antagonist used for luteinizing hormone-suppression.The quality of oocytes and developing preembryos is one of the most relevant factors determining the success of an In-Vitro Fertilization treatment. As ovarian stimulation protocol is one of the eligible factors during an In-Vitro Fertilization treatment, its embryo quality influencing effects are necessary to know.
Interventions
DRUGGonadotropin-Releasing Hormone Analogue
Triptorelin at a dose 1 mg per day from the midluteal phase of the cycle preceding the treatment cycle to day 2 of the cycle then 0.5 milligram of triptorelin will be used during the period of stimulation.
antagonist group :Multiple dose gonadotrophin-releasing hormone antagonist regimen will be used for ovarian stimulation 0.25 microgram per day cetrorelix will be administered from the 6th day of ovarian stimulation or from the presence of follicle 14 millimeter diameter .We will give them gonadotrophin for 5 days , Triggering by Human Chorionic Gonadotrophin will be administered for each group when size of follicle reach \> 17 millimeter .Oocytes will retrieved by transvaginal ultrasound , 34-36 hours after Human Chorionic Gonadotrophin administration .
