OBJECTIVE: There is a paucity of literature on the impact of bariatric surgery on artificial reproductive technology (ART) outcomes. This topic should be examined, given that most bariatric surgery candidates are of reproductive age and those with obesity are significantly more likely to experience poor fertility outcomes. This systematic review aimed to determine if bariatric surgery impacts ART outcomes and if effects vary between females and males.
DATA SOURCES: MEDLINE, EMBASE, SCOPUS, and the Cochrane Central Register of Controlled Trials were searched for English studies published between January 1978 and May 2021.
STUDY SELECTION: Studies with participants who had received bariatric surgery and subsequently underwent ART (i.e., in vitro fertilization or intracytoplasmic sperm injection) were eligible for inclusion. Screening, data abstraction, and risk of bias assessment were conducted independently and in duplicate.
DATA EXTRACTION AND SYNTHESIS: Of the 279 articles screened for eligibility, 25 were sought for full text review, and 7 were included for analysis. Four studies (57%) examined ART interventions in females, while 3 (43%) examined interventions in males. Data on cumulative live birth rate (CLBR) was extracted for all 7 studies (N = 169). There were 50 live births with CLBRs ranging from 0.0% to 80.0%. Data on female secondary outcomes were varied. Data on male secondary outcomes were contradictory: 1 study indicated improved sperm parameters following bariatric surgery, while 2 showed decreased parameters, with certain participants seeing improvements after several months.
CONCLUSION: Bariatric surgery prior to ART may have an impact on CLBRs; however, high-quality research is needed to delineate the direct effects of bariatric surgery on ART outcomes. Various sex-specific outcomes should be considered prior to recommending ART after bariatric surgery. Future research should determine the optimal type of bariatric surgery and timing of ART following bariatric surgery.
