Protocol summary
Study aim
Improving the number and quality of follicles in people with decreased ovarian reserve
Design
In this clinical trial without a control group, without blinding,10 patients with decreased ovarian reserve (based on inclusion and exclusion criteria) are subjected to IVA surgery in one ovary,
Settings and conduct
10 patients suffering from decreased ovarian reserve (based on entry and exit criteria) referred to Tehran Taleghani Hospital's Infertility Center underwent IVA surgery in one ovary and as a clinical trial without control group, without blinding of Fsh /AMH /E2 serum levels. And the number of AFC has been investigated and the patients enter the ovulation stimulation cycle 90 days later.On the day of the operation, patients are subjected to general anesthesia and laparoscopy. A part of the cortex of an ovary is removed from it (size of each biopsy ~5x5x3 mm) and after pathology staining, it is immediately transferred to the adjacent embryology laboratory. The ovary sample is immediately cut into small cubes (1 x 1 x 1 cubic mm) and returned to the ovary. After 3 months, patients enter ovulation stimulation cycles.
Participants/Inclusion and exclusion criteria
The inclusion criteria: < 40 yr old, in POSEIDON group III or IV , AFC<5 ,AMH< 1.2 ng/dl,FSH levels < 10 IU/L with a history of at least one failed stimulation cycle resulting in the inability to retrieve oocyte. Participants with male factor infertility and positive history of hydrosalpinx or anatomical uterine disorders and endocrine disease were excluded from the study.
Intervention groups
Patients younger than 40 years old underwent an ovarian reserve decline who underwent IVA and before and after it were evaluated for primary and secondary outcomes.
Main outcome variables
The count of retrieved oocytes,
number of oocytes metaphase II,
the quantity of embryos transferred,
implantation rate
clinical pregnancy rate.
General information
Reason for update
Due to the initial registration in the work study system, the clinical trial and the completion of the collection of samples, follow-up of patients and analysis of the obtained results, updating is done in the system.
According to the pilot study, according to the co-worker's discretion, the sample size increased from 6 to 10 cases.
