An observational study in DNA Damage and Granulosa Cells, sponsored by Zeynep Kamil Maternity and Pediatric Research and Training Hospital. Status unknown. Open to female participants aged 18 Years to 35 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2022-09-28.
Sponsored by Zeynep Kamil Maternity and Pediatric Research and Training Hospital · Observational
Deoxyribonucleic acid (DNA) damage of granulosa cells obtained during oocyte retrieval will be evaluated by flow cytometry with detection of Histone H2A.X and Phosphorylated Gamma H2A.X protein levels in patients with low ovarian reserve and unexplained infertile patients as a control group undergoing intracytoplasmic sperm injection (ICSI) treatment. Fertilization, embryo quality, transfer rate, implantation, clinical pregnancy will be recorded as well as demographic data. DNA damage of granulosa cells will be compared between two groups. The effect of DNA damage of granulosa cells on fertilization, quality of oocyte and embryo, implantation, and clinical pregnancy will be also evaluated.
Granulosa cells surrounding the oocytes will be mechanically obtained during the oocyte pick-up procedure in women undergoing intracytoplasmic sperm injection (ICSI) treatment due to unexplained infertility and low ovarian reserve. Deoxyribonucleic acid (DNA) damage in these cells will be evaluated by flow cytometry. Fertilization rates, embryo quality by grading, and transfer rates will also be assessed. Implantation and clinical pregnancy rates will be recorded as well as demographic data such as age, body-mass index, smoking, alcohol use, employment, coexisting chronic disease, infertility duration, etiology of infertility, treatment protocol. Implantation will be evaluated by determination of serum human chorionic gonadotropin (hCG) at day 15 following an embryo transfer. Clinical pregnancy will be diagnosed upon presence of gestational sac on ultrasound examination. DNA damage of granulosa cells will be compared between low ovarian reserve group and control group. The effect of DNA damage of granulosa cells on fertilization, quality of oocyte and embryo, implantation, and clinical pregnancy will be also evaluated.
Zeynep Kamil Maternity and Pediatric Research and Training Hospital is the lead sponsor of 38 studies on the registry; none are open to participants now.
Counted across the registry records on this site, refreshed daily.
Low ovarian reserve group will be included as Antimullerian hormone level results as lower than 1 ng/ml without any other infertility evidence.The control group received IVF for Unexplained infertile (UI) group UI was diagnosed after normal standard infertility evaluation according to the guideline of The Practice Committee of the American Society for Reproductive Medicine which consist of the assesment of spermiogram, ovulation, hysterosalpingogram and if indicated ovarian reserve tests and laparoscopy as well as Antimullerian hormone level results as greater than 1,5 ng/ml. If the results of all this tests were normal, patients were accepted as UI.

Exclusion Criteria:
Patients diagnosed as low ovarian reserve were recruited to the study who have Antimüllerian Hormone level of 1 ng/ml or lower. Patients with low ovarian reserve were diagnosed after normal standard infertility evaluation according to the guideline of The Practice Committee of the American Society for Reproductive Medicine which consist of the assesment of spermiogram, ovulation, hysterosalpingogram and if indicated ovarian reserve tests and laparoscopy. Male infertility is an exclusion.
Patients diagnosed as unexplained infertility (UI) were recruited to the study who have Antimüllerian Hormone level of 1.5 ng/ml or higher as a control group. UI was diagnosed after normal standard infertility evaluation according to the guideline of The Practice Committee of the American Society for Reproductive Medicine which consist of the assesment of spermiogram, ovulation, hysterosalpingogram and if indicated ovarian reserve tests and laparoscopy.
Determining the correlation of ovarian reserve and age factor with DNA Damage markers in granulosa cells.
Demographic data will be noted for each patient at the day of oocyte retrieval, and DNA damage markers will be shown by flowcytometry at the same day.
