Sperm count and bmi

[naty1]

I think its supposed to affect count. Im wondering of those doing icsi what their partners bmi is.
Especially as for women nhs has a bmi limit.
Did anyones partner lose a lot of weight and that helped conception/their count?

I think my DH was just a teeny bit outside his bmi, but they didn't say anything. He naturally pretty fit though, just got this big beer belly even though he massively cut down on drinking.

Thanks Allchat. Is that his bmi is just over 30? Or 25?

This metanaylsis does suggest that there is a link between high BMI and poor sperm counts, but also says it is an under researched area.

Given that lifestyle and healthy diet are known to affect both sperm production and weight, the hypothesis that there is a link remains plausible even if not adequately proven (or at least not disproven). And there is certainly no harm in adopting healthier eating habits with the aim of reducing both weight and any condition that is associated with excess weight.

And it is definitely true that sperm counts change over time.
