I've posted before about different clinic approaches, my AFC is often 1 or 2 (sometimes 3 or 4) on day 3. I have not been capable of responding well for quite a few years. I genuinly think with a very low AMH and AFC the most cost effective approach is as close to natural as you can get. If you have an AFC of 5/6/7/8 then a mild approach will give you the best shot.
We chose not to go with CRGH even though we had consults with them and were impressed becuase we would only be able to afford 1 cycle where we could afford 3 elsewhere. We used Serum in Athens mainly.
Covid can affect male fertility in the same way any nasty virus can, it should be tempory 3months of so and the effects should be gone, although you can use the time to put him on a sperm imporvement protocol, Proxceed, plus a long course of antibiotics, plus Vit C 1000mg and Vit E 400mg plus some ubiquinol are a start for him.
DHEA didn't work for me, it appears to work well for some women and not for others, and it actually made things worse for me (rather than better). I have a couple of theories about why to do with Oetrogen metabolism and breakdown (Oestrogen Dominance), but there isn't much evidence to know who it might benefit and who it might hinder a bit better. It took a very long time to clear it from my system as well (over 6 months) and I needed a lot of detoxing. It would be interesting to know what they feel but definately ask them about the down sides as well as the positivies and if there is a way or test to be able to tell which group you are more likley to fit into.
