The intriguing anomaly only applies to when the eggs are collected, not when they&rsquo;re implantedenCommunityServer 2008.5 SP1 (Debug Build: 31106.3070)https://blogs.mercola.com:443/sites/vitalvotes/archive/2023/07/11/ivf-success-is-higher-if-eggs-harvested-in-summer.aspx?ShowAllComments=True#13280867/12/2023 12:24:32 PM24451277-a5aa-4add-96dc-64081bfd86fa:1328086Villainesse<p>My Covid-educated guess? It&#39;s the higher UVB leading to better D LEVELS! D &amp; Melatonin both affect our sex hormones, organs and sleep quality. They should start by simply comparing patients&#39; D levels with the success rates. Patients who supplement to maintain great levels year round may have no seasonal variation in success rates. If correlated, then more involved studies could attempt to define the mechanisms.</p> https://blogs.mercola.com:443/sites/vitalvotes/archive/2023/07/11/ivf-success-is-higher-if-eggs-harvested-in-summer.aspx?ShowAllComments=True#13279027/11/2023 4:59:16 PM24451277-a5aa-4add-96dc-64081bfd86fa:1327902hils<p>Animals give birth when the weather is most favourable for their survival.</p>
