Biba - wishing you a warm welcome and hoping that your dreams are soon realised after so many hurdles.
Esperanza - our FS the infamous Wazza, used to tell us to do the deed the night of EPU and then the night before TF. I recall him saying it was to catch any wayward eggs following trigger (not relevant for ED recipient as we don't actually ovulate during an ED cycle) and the other was to 'prep' the uterus and provide nutrients (sugars from sperm). So with that in mind we kept to the usual IVF protocol for our ED cycle.
Also DH specimen was required for the day of the donors EPU. We did our cycle in Joburg, but also left a later sample in CT, just in case I had to return for a further cycle. Hope that helps
