Remember it was late 1970s though, so there may have been some kind of examination, or consultation at the least. Completely intrusive and unnecessary regardless!
On the KM front Mr Ellis and I were struggling to conceive around the time of the wedding and I remember saying that I bet she’ll have had some kind of tests prior to getting married, such as the day 3 & 21 bloods and urine tests and the test to establish AMH (quality and quantity of eggs). Not that it would have a bearing on whether the wedding would go ahead, but prudent to have the professional assistance teed up if need be. She wouldn’t be fighting with her GP to get a referral onto an IVF waiting list anyway...
