I'm so sorry to hear this Scotchegg! My hubby (sperm count 4 million) also took Pycnogenol after Bead told us and multivitamins, and he wasn't at all allowed to have the laptop/phone near his parts.
About the sex, we had sex almost every day, so we tried to cut back a bit and "save" up some sperm cells a couple of days before my ov. I'm not sure why I got pregnant (but I did after 15 months of ttc), might be the extra ewcm I had, or might just be pure luck, but I'm convinced that the vitamins, antioxidants, ewcm and the "saving" were all parts of it.
Hope you figure something out and that you feel better soon!
