Abstract

Importance: The prevalence of oocyte donation for in vitro fertilization (IVF) has increased in the United States, but little information is available regarding maternal or infant outcomes to improve counseling and clinical decision making.

Objectives: To quantify trends in donor oocyte cycles in the United States and to determine predictors of a good perinatal outcome among IVF cycles using fresh (noncryopreserved) embryos derived from donor oocytes.

Design, setting, and participants: Analysis of data from the Centers for Disease Control and Prevention's National ART Surveillance System, to which fertility centers are mandated to report and which includes data on more than 95% of all IVF cycles performed in the United States. Data from 2000 to 2010 described trends. Data from 2010 determined predictors.

Main outcomes and measures: Good perinatal outcome, defined as a singleton live-born infant delivered at 37 weeks or later and weighing 2500 g or more.

Results: From 2000 to 2010, data from 443 clinics (93% of all US fertility centers) were included. The annual number of donor oocyte cycles significantly increased, from 10,801 to 18,306. Among all donor oocyte cycles, an increasing trend was observed from 2000 to 2010 in the proportion of cycles using frozen (vs fresh) embryos (26.7% [95% CI, 25.8%-27.5%] to 40.3% [95% CI, 39.6%-41.1%]) and elective single-embryo transfers (vs transfer of multiple embryos) (0.8% [95% CI, 0.7%-1.0%] to 14.5% [95% CI, 14.0%-15.1%]). Good perinatal outcomes increased from 18.5% (95% CI, 17.7%-19.3%) to 24.4% (95% CI, 23.8%-25.1%) (P < .001 for all listed trends). Mean donor and recipient ages remained stable at 28 (SD, 2.8) years and 41 (SD, 5.3) years, respectively. In 2010, 396 clinics contributed data. For donor oocyte cycles using fresh embryos (n = 9865), 27.5% (95% CI, 26.6%-28.4%) resulted in good perinatal outcome. Transfer of an embryo at day 5 (adjusted odds ratio [OR], 1.17 [95% CI, 1.04-1.32]) and elective single-embryo transfers (adjusted OR, 2.32 [95% CI, 1.92-2.80]) were positively associated with good perinatal outcome; tubal (adjusted OR, 0.72 [95% CI, 0.60-0.86]) or uterine (adjusted OR, 0.74 [95% CI, 0.58-0.94]) factor infertility and non-Hispanic black recipient race/ethnicity (adjusted OR, 0.48 [95% CI, 0.35-0.67]) were associated with decreased odds of good outcome. Recipient age was not associated with likelihood of good perinatal outcome.

Conclusions and relevance: In the United States from 2000 to 2010, there was an increase in number of donor oocyte cycles, accompanied by an increase in good outcomes. Further studies are needed to understand the mechanisms underlying the factors associated with less successful outcomes.
