Abstract
Purpose
To compare national trends and perinatal outcomes following the use of ejaculated versus surgically acquired sperm among IVF cycles with male factor infertility.
Methods
This retrospective cohort includes US fertility clinics reporting to the National ART Surveillance System between 2004 and 2015. Fresh, non-donor IVF male factor cycles (n = 369,426 cycles) were included. We report the following outcomes: (1) Trends in surgically acquired and ejaculated sperm. (2) Adjusted risk ratios comparing outcomes for intracytoplasmic sperm injection (ICSI) cycles using surgically acquired (epididymal or testicular) versus ejaculated sperm. (3) Outcomes per non-canceled cycle: biochemical pregnancy, intrauterine pregnancy, and live birth (≥ 20 weeks). (4) Outcomes per pregnancy: miscarriage (< 20 weeks) and singleton pregnancy. (5) Outcomes per singleton pregnancy: normal birthweight (≥ 2500 g) and full-term delivery (≥ 37 weeks).
Results
Percentage of male factor infertility cycles that used surgically acquired sperm increased over the study period, 9.8 (2004) to 11.6% (2015), p < 0.05. The proportion of cycles using testicular sperm increased significantly over the study period, 4.9 (2004) to 6.5% (2015), p < 0.05. Among fresh, non-donor male factor ART cycles which used ICSI (n = 347,078 cycles), cycle, pregnancy, and perinatal outcomes were statistically significant but clinically similar with confidence intervals approaching one between cycles involving epididymal versus ejaculated sperm and between testicular versus ejaculated sperm. Results were similar among cycles with a sole diagnosis of male factor (no female factors), and for the subset in which the female partner was < 35 years old.
Conclusion
Among couples undergoing ART for treatment of male factor infertility, pregnancy and perinatal outcomes were similar between cycles utilizing ejaculated sperm or surgically acquired testicular and epididymal sperm.
