IUI (Intrauterine Insemination): Success Rates, Risks, Uses, and More
Background : This systematic review and meta-analysis aims to establish the effects of bariatric surgery on male sex hormones, sperm parameters, and sexual function.

The literature on the effect of bariatric surgery on male sex hormones and sperm quality is considerable and has not been comprehensively reviewed and meta-analyzed. Articles were eligible for inclusion if the studies examined the effect of bariatric surgery on male sex hormones and sperm parameters in patients with obesity. Pooled estimates were calculated using random effects meta-analyses and heterogeneity was quantified using the inconsistency I2 statistic.



Intrauterine Insemination (IUI)
During natural conception, sperm have to travel from the vagina through the cervix, into the uterus, and up to the fallopian tubes. This process can increase the likelihood of pregnancy in certain couples who have had difficulty getting pregnant. IUI is a relatively noninvasive and less-expensive fertility treatment compared to more invasive and costly treatments such as in vitro fertilization IVF.
