Summary
This study compared in-vitro fertilization (IVF) outcomes after removing either the right or left ovary. Results show no significant difference in IVF success rates regardless of which ovary was removed.
Area of Science:
- Reproductive Endocrinology
- In-Vitro Fertilization
- Ovarian Function
Background:
- Ovarian response to stimulation can vary.
- Previous studies have not definitively compared IVF outcomes based on unilateral oophorectomy.
Purpose of the Study:
- To investigate if the side of oophorectomy (right vs. left) impacts in-vitro fertilization (IVF) outcomes.
- To determine if gonadotrophin-releasing hormone and human menopausal gonadotrophins (GnRH/HMG) stimulation protocols show ovarian predilection.
Main Methods:
- Retrospective comparison of 56 IVF cycles post-left oophorectomy (Group A) versus 42 cycles post-right oophorectomy (Group B).
- All patients had tubal disease as the sole cause of infertility.
- Standard GnRH/HMG ovulation induction protocol used.
Main Results:
- No significant differences observed between groups in age, HMG dosage, days of HMG, peak estradiol levels, oocytes retrieved, or fertilization rates.
- Identical pregnancy rates were achieved: 20.0% in Group A and 20.9% in Group B.
Conclusions:
- The side of oophorectomy does not influence IVF outcomes using GnRH/HMG stimulation.
- Ovarian response and IVF success rates are comparable irrespective of whether the right or left ovary was removed.
