Brief Summary:
The aim of this study is to evaluate calcium ionophore solution on fertilization rate of patients during intracytoplasmic sperm injection who have poor ovarian reserve

Condition or disease Intervention/treatment Phase
Fertilization Failure Other: calcium ionophore solution Not Applicable

Detailed Description:
During ICSI cycle , female patients who have poor ovarian reserve have low oocyte numbers. So by calcium ionophore solution which we know that it can increase fertilization rate in males who have azospermia or globozoospermia. we planned to check if this solution can increase fertilization rate also in poor ovarian reserve patients?

Arm Intervention/treatment
No Intervention: control group
the patients who have no intervention with calcium ionophore during ICSI cycle
Experimental: calcium ionophore
the patients whose oocytes are incubated with calcium ionophore solution during ICSI cycle
Other: calcium ionophore solution
After microinjection of sperm into the oocyte, oocytes are incubated for 15 minutes in a 30 microlitre droplet of calcium ionomycin solution
Other Names:
  • GM 508 Cult-Active (Gynemed)
  • ionomycin

Primary Outcome Measures :
  1. calcium ionophore solution effect on fertilization rate [ Time Frame: 18 hours ]
    Before Intracytoplasmic sperm injection adding calcium ionophore solution to the medium can increase fertilization rate of oocytes or not?

Secondary Outcome Measures :
  1. Calcium ionophore solution increase on going pregnancy rate [ Time Frame: up to 21 weeks ]
    İf the calcium ionophore can increase fertilization rate , pregnancy rate up to 20 weeks, can increase or not?

Other Outcome Measures:
  1. calcium ionophore can decrease fertilization rate [ Time Frame: 18 hours ]
    To detect if calcium ionophore can affect fertilization rate in a reverse manner than expected
