Hi MrsDarcy. I assume this appointment is with a consultant, do you know? If so, I don't have experience of male factor but I would expect they will give you their opinion on the best course of action at the appointment. Have you had any blood tests yet? That might affect whether they are able to recommend long/short protocol at this point, but if not, they will schedule them at this appointment.
Consultant appointments I have found last up to about half an hour, and then you usually have 5-10 minutes with a nurse as there's always paperwork to do and next appointments to book. It might be more than 10 mins if it's your first appointment as there's a lot of forms to read and sign to start with.
I can't see why starting end of april / start of may would not be realistic but couldn't say for sure. The thing is that as well as an AMH test for you and scan to check follicle count, there are various screening tests that you both need to have before starting including a hepatitis and HIV screen, chlamydia tests, you need to have an up to date smear test, and a rubella immunity test within the last 3 years. These can take time - doing them all at VW will be faster but more expensive. The nurse will tell you how much all of them will cost at VW so you can decide. We had them all done on NHS before our fresh cycle, but when I've had to update rubella and chlamydia tests for frozen cycles I've just done them at VW as they are only about £50 each.
We didn't get weighed and measured that I recall, however I don't know whether heavier people might be. If the problem is with your DH and not you then I can't see that they'd be fussed about your weight, and surely not his if his problems are that severe it's not like dropping a few pounds would make a difference.
Good luck!! It's exciting, that first appointment. But also daunting, there's so much to think about and so many forms to sign. The staff there are so lovely though so it does help. Just a word of warning there are hundreds of photos of their babies all over the walls!! I like it, now, but that first time you go in there I was a bit, wtf?!! Somewhere there's a pic of our DD in there but I've never managed to find it!!
