When You ’re Told You’re Too Fat to Get Pregnant

Does it make sense, medically or ethically, when fertility clinics refuse to treat prospective mothers they consider too large?

Rossi, Olav LapaireAbstractAlthough an increased risk of pre-eclampsia in pregnancies conceived after infertility treatment has been reported, it remains unknown whether preconceptional minimalisation of known risk factors would help in preventing pre-eclamsia. Obesity and preconceptional blood pressure are discussed as major risks for...

AbstractPurposeTo assess the effect of body mass index (BMI) on morphokinetic parameters of human embryos evaluated with time-lapse technology during in vitro culture.MethodsA retrospective analysis of ART cycles utilizing time-lapse technology was undertaken to assess the potential impact of maternal BMI on morphokinetic and static morphological parameters of embryo development. The cohort of patients was divided into four groups: 593 embryos from 128 underweight women in group A; 5248 embryos from 1107 normal weight women in group B; 1053 embryos from 226 overweight women in group C; and 286 embryos from 67 obese women i...

CONCLUSIONS: By triggering multiple inflammatory and oxidative pathways, the combined administration of SrE, selenium and lycopene might likely improve the sperm quality. Proper studies are needed to test this hypothesis. Finally, since prostatitis can affect the sperm quality and considering the anti-estrogenic properties of SrE, we speculate about a possible specific indication in those patients with male infertility and "metabolic" prostatitis (where obesity and abnormal androgen/estrogen ratio concomitantly occur).

In this study, 8-week-old mice were randomly divided into four groups. Mice were fed a normal diet or an HFD with or without SFN supplementation. SFN was subcutaneously injected at a dose of 0.5 mg/kg 5 days/week for 4 weeks beginning 8 weeks after initiation of the HFD. The results demonstrated that SFN could protect against HFD-induced reproductive dysfunction in male mice. Moreover, SFN also improved reproductive ability, as demonstrated by an increased pregnancy rate and decreased embryo resorption rate in comparison to the corresponding HFD group. We also observed a decrease in apoptosis and an attenuation of endoplas...

Conclusion The periconceptional environment and lifestyle factors modify sperm epigenome. This alteration might be maintained in the zygote and throughout development, thereby leading to the inheritance of newly acquired pathologies. The role of sperm miRNA, not only as innovative markers of fertility issues but also as vectors involved in the inheritance of paternal diseases, appears to be crucial. Overweight and obesity seem to alter sperm miRNA profile, thereby leading to transmission of different miRNA profiles in zygote, with consequences on embryo development. In long term, metabolic disorders have been described in...

CONCLUSION: Advanced maternal age women are at a higher risk of adverse obstetrical and perinatal outcomes. In both comparisons, worse outcomes were more prevalent in the older group, suggesting that poorer outcomes are more prevalent with increasing age. PMID: 30946794 [PubMed - in process]

More than 1/3 of reproductive-age females in the United States are obese.[1] When compared to normal-weight women, obese women are more likely to be infertile and less likely to achieve clinical pregnancy with IVF, possibly due to a negative association between obesity and endometrial receptivity.[2-4]
