Now what I want to ask you is quite delicate. I don’t, I think, produce much when I ejaculate. So I wondered if that might be a problem in fathering children? She is also desperate to have babies, and would be a perfect mother, just as I’d be a very enthusiastic father. And I’d even welcome the chance to change nappies, feed, and get out of bed to see to the little ones, if they called out in the night.

I’m clean, tidy, a good cook, and enjoy doing my share of all housework and shopping. So, how do I find out if I could actually father a child? I don’t want to mislead my partner into thinking that I can give her babies, if I can’t. Should I adjust my diet to increase her chance of conceiving? I like sharing the odd glass of wine from time to time. Is that going to affect my ability to father a child? Is there any dietary advice you can give me?

I so much want us to be a happy family, with as many babies as we can afford!

Barbara says: Lots of questions here, so let me answer with some evidence from my own casebook. I have a client who has just fathered his second child at the age of 66. He also uses Viagra. So that’s not a problem, in his case – plus he’s partial to gin and tonic, wine and beer.

Fertility often depends on the woman. Just one little sperm creates a baby, and if she’s up for it, and you have unprotected sex, as long as she hasn’t had Chlamydia, you have a good chance that her fertility will be fine at about days 12 to 16 of her cycle, although any time at all can be good enough!

Go to your GP who can arrange for you to have a sperm count through the NHS. Even if that is low, it means little, if you’re determined. You can get enhancement procedures through the NHS which are less invasive than IVF in most cases, but I’d advise leaving it to nature for a couple of years. All the best! Let me know, and all the readers know, too, if you make it. I think you will.
