Fertility after Ipilimumab/Yervoy

Hi, I'm a 32 year old woman with Stage 4 melanoma, based in the UK. I'm about to start on Ipilimumab, following a surgey to remove a met where the surgeons didn't manage to get clear margins.

I just wanted to do a quick survey to see if anyone knew of any female patients still able to become pregnant after their Ipi treatment.

There doesn't seem to be any official info, and  I'm trying to weigh up the likelihood of having any future fertility problems. My oncologist is generally great, but he's a bit unhelpful on this point, saying that if I were male then he'd recommend freezing sperm as it's easy and relatively cheap, but that for me it will be expensive, delay my treatment and is more likely to be unsuccessful anyway as the whole process has more problems. The lack of clear data also means that, in the UK, any pre-emptive egg-harvesting/freezing isn't funded. I understand that by pushing for it I would potentially put my health at risk but at the same time I'm nervous about making a decision now that I will regret later – I guess we're all just trying to make the best decision at the time, and hopefully a bit of extra info from you guys will help in that.

Thanks is advance for any help, info and advice you can offer!
