I was just watching that Sex Education show on C4 and it just made me wonder, this is potentially a really stupid question, but do fertility problems run in families? The reason I think this is likely to be a silly question is because obviously my mum got pregnant with me and my brothers and sister. But some ppl do struggle to get pregnant but do eventually and I was just wondering if this is something that can be inherited? If it is, I think I'm fortunate because none of my family seem to have problems making babies, except my sister. She took a year to conceive but I think that was because she had a cyst on her ovary. Anyone have any ideas on this?
