The short-term efficacy in terms of improvement of sexual function and safety of transdermal T in naturally and surgically menopausal women affected by HSDD either on or not on estrogen progestin hormone therapy is evident from this systematic review. The use of transdermal T is associated with increase in androgenic adverse events such as acne but is not associated with any serious adverse events.
Men with a body mass index (BMI) of 30 or over are more likely to have reduced fertility and fecundity rates. This systematic review and meta-analysis evaluated the effect of male BMI on IVF and intracytoplasmic sperm injection (ICSI) outcome. An electronic search for published literature was conducted in MEDLINE and EMBASE between 1966 and November 2016. Outcome measures were clinical pregnancy rates (CPR) and live birth rates (LBR) per IVF or ICSI cycle. Eleven studies were identified, including 14,372 cycles; nine reported CPR and seven reported LBR. Pooling of data from those studies revealed that raised male BMI was associated with a significant reduction in CPR (OR 0.78, 95% CI 0.63 to 0.98, P = 0.03) and LBR (OR 0.88, 95% CI 0.82 to 0.95, P = 0.001) per IVF-ICSI treatment cycle. Male BMI could be an important factor influencing IVF-ICSI outcome. More robust studies are needed to confirm this conclusion using standardized methods for measuring male BMI, adhering to the World Health Organization definitions of BMI categories, accounting for female BMI, IVF and ICSI cycle characteristics, including the number of embryos transferred and embryo quality, and use the live birth rate per cycle as primary outcome.
IntroductionIntracytoplasmic morphologically selected sperm injection (IMSI) is one of the sperm selection techniques used for assisted reproduction which has been applied for a variety of indications including previously failed fertilization with intracytoplasmic sperm injection (ICSI). A Cochrane review1 found no difference in outcomes between either modality of sperm selection. Since the Cochrane review was published there have been a further two randomized controlled trials comparing IMSI and ICSI. This systematic review and meta‐analysis aims to compare IMSI with ICSI as insemination methods regarding live birth rate and miscarriage rate.Material and methodsSystematic review of randomized controlled trials, observational studies and similar reviews in electronic databases published before January 2018.ResultsWe found nine randomized controlled trials, evaluating 1610 cycles of in vitro fertilization and 15 observational studies evaluating 1243 cycles of in vitro fertilization. Meta‐analysis of the included randomized controlled trials showed no difference in the live birth rate or miscarriage rate between the ICSI and IMSI groups. Meta‐analysis of five observational studies showed a significantly higher number of live births in the IMSI group than ICSI group (live birth rate odds ratio 1.47, 95% confidence interval 1.16‐4.07), with a moderate degree of heterogeneity (I2 = 41%). Additionally, from six observational studies, a significantly lower miscarriage rate was observed in the IMSI group than in the ICSI group (odds ratio 0.51, 95% confidence interval 0.37‐0.70, I2 = 0%).ConclusionsMeta‐analysis of randomized studies comparing IMSI to ICSI has not shown any difference in live birth rate and miscarriage rate. Meta‐analysis of observational studies, which must be interpreted with caution, revealed an increased live birth rate and decreased miscarriage rate with IMSI vs ICSI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
