Low motility & Morphology

Just thought I’d share something we noticed recently. We have a MFI diagnosis of low morphology & motility. After going on vacation we noticed motility had slightly improved after a sperm analysis. We attributed it to less stress (dh has a stressful job). Since, it was a beach vacation we got a lot of sun so I figured it might be his Vit D might have been low. So he started taking Vit D supplements the most recent sperm analysis shows normal motility. Morphology was still low but male fertility specialist said it’s a controversial value. His prenatal did have some Vit d in it but possibly not enough since we live in a rainy area. We’ve been ttc for 1.5 years.
