Effects of uterine adenomyosis on clinical outcomes of infertility patients treated with in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) / 南方医科大学学报

<p><b>OBJECTIVE</b>To explore the effects of uterine adenomyosis on the clinical outcomes of infertility patients treated with in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET).</p><p><b>METHODS</b>A retrospective study was conducted of 61 IVF/ICSI-ET cycles as the study group, diagnosed with uterine adenomyosis by transvaginal ultrasound, and 164 IVF/ICSI-ET cycles of patients with tubal infertility as the control group. The baseline characteristics, ovary response and clinical outcomes were compared between the two groups.</p><p><b>RESULTS</b>The implantation rate, clinical pregnancy rate and live birth rate decreased significantly in the study group (P<0.05), and early abortion rate increased significantly (P<0.05). For patients with adenomyosis, GnRH-antagonist cycles tended to decrease clinical pregnancy rate and increase abortion rate (25.0% vs 45.0%, P=0.184; 66.7% vs 27.8%, P=0.247), and significantly decrease live birth rate (0% vs 30.8%, P=0.025), compared with GnRHa agonist cycles.</p><p><b>CONCLUSION</b>Uterine adenomyosis decreases implantation rate, clinical pregnancy rate and birth rate, and increases abortion rate significantly in patients with IVF/ICSI-ET. GnRH-antagonist cycles have adverse effects on the outcomes of adenomyosis; GnRH agonist long protocol cycles may increase clinical pregnancy rate and decrease abortion rate.</p>

Successful pregnancy in women with infertility following surgeries for gynecological malignancies: report of 3 cases and literature review / 南方医科大学学报

We report 3 cases of successful pregnancies in women with a history of surgeries for gynecological malignancies and postoperative infertility, achieved by in vitro fertilization-embryo transfer (IVF-ET) with controlled ovarian hyperstimulation. All the 3 patients had clinical pregnancies without cancer recurrence. In such cancer survivors with infertility, the ovarian reserve is severely impaired by cancer therapies and assisted reproductive techniques should be the primary option.
