Purpose:
To determine if oocyte donors aged 36-39 can provide adequate pregnancy rates for recipients.
Methods:
Retrospective analysis of clinical, ongoing/delivered pregnancy and implantation rates for a group of recipients receiving oocytes from a pilot group of older donors.
Results:
Comparable pregnancy and implantation rates were found in recipients transferring embryos derived from donors aged 36-39 as recipients using oocytes from donors < or = 35.
Conclusions:
The demonstration of adequate outcome following embryo transfer from embryos derived from fertilization of oocytes from donors aged 36-39 should expand the pool of donor oocytes and reduce the long waiting times for recipients.
