Study type
Description of intervention(s) / exposure
Induction of ovulation will be done by letrozole tablets 5 mg mg /day from day 2 to day 6 of the participant's menstrual cycle then human menopausal gonadotropins ( HMG ) ampoules (fostimon ;IBSA) ( 150-225 IU /day ) will be given intramuscular according to patients response started from day 7 of menstrual follow till the day of human chorionic gonadotropin (HCG) -which is a hormone similar to endogenous lutienizing hormone to trigger ovulation-in a dose of 10000 iu intramuscular when the dominant follicle reaches 17 mm .
ovum pick up for Intracytoplasmic sperm injection (ICSI ) will be done 34-36 hours after HCG adminstration.
Intervention code [1] 288261 0
Treatment: Drugs
Comparator / control treatment
Induction of ovulation will be done by HMG ampoules(fostimon ; IBSA) alone using a dose of 150- 225 IU / day intramuscular injection and tailored according to patient’s response starting from the second day of the natural or induced menstrual flow till the day of human chorionic gonadotropin (HCG) that will be given in a dose of 10000 iu intramuscular when the dominant follicle reaches 17 mm .
ovum pick up for ICSI will be done 34-36 hours after HCG adminstration.
Control group

Primary outcome [1] 290860 0
the number of oocytes obtained through ovum pickup by transvaginal ultrasound guided aspiration through identification of oocyte under microscopy after ovum pickup
Timepoint [1] 290860 0
Approximately 34 - 36 hours after HCG administration
Primary outcome [2] 290861 0

Timepoint [2] 290861 0
1-2 hours after ovum pick up
Secondary outcome [1] 305482 0
Gonadotropins dosage and duration of induction ( composite outcome ) dated from the start of ovulation induction until the day of HCG and from number of days we will calculate the total dose of gonadotropins by muliplying the dose per day by the number of days .
Timepoint [1] 305482 0
from the start of induction to be monitored very 2-3 days until the day of HCG administration
Secondary outcome [2] 305483 0
fertilization rate ( the number fertilized oocytes divided by the number of injected mature oocytes)
Timepoint [2] 305483 0
18-24 hours after oocyte pickup
Secondary outcome [3] 305484 0
number of embryos assessed under microscopy
Timepoint [3] 305484 0
at day three of ovum pickup
Secondary outcome [4] 305485 0
grades of embryos through scoring of embryos using the fragmentation percentage , equality of the cells and number of cells in embryos (8 cells at day 3 )
Timepoint [4] 305485 0
at day 3 post ovum pickup
Secondary outcome [5] 305486 0
chemical pregnancy rates by measuring serum quantitative HCG level
Timepoint [5] 305486 0
14 days after oocyte pickup (as mentioned before oocyte pickup done after 34-36 of HCG adminstration)
Secondary outcome [6] 305487 0
clinical pregnancy rate through visualization of cardiac pulsation
Timepoint [6] 305487 0
6-8 weeks after oocyte pickup(as mentioned before oocyte pickup done after 34-36 og HCG adminstration)
