Why aren't we talking about the male fertility crisis?

Link to an article in the DT - https://www.telegraph.co.uk/health-fitness/body/arent-talking-male-fertility-crisis/


On Wednesday, as part of Fertility Network UK’s #YouAreNotAlone Fertility Week, the charity will focus specifically on men: reminding us that while male infertility is as prevalent as female, it often goes unspoken and untreated, leaving men in a lonely struggle with the emotional, physical and financial fall-out.

“For some guys, there is an incredible sense of shame involved, because we attach siring a child to masculinity so closely,” Voysey says.

The author and broadcaster has always been happy to identify himself as “the problem” in his and his wife, Merryn’s infertility struggle, in the hope that he can help shift this taboo, much the way we have with male depression.

Japan has a bit of problem in that respect i think.
Japan, China, South Korea, most of western Europe, all have a reproductive rate below 2. As other economies develop I can't see why couples won't make the same decision, which if not reversed will result in mankinds extinction in a surprisingly short timescale. Prior to that it will cause some interesting economic issues.

So a reproductive rate of 2?

Muliply each generation by two and in about twenty generations you have a million...and you reckon that will lead to extinction?
If each couple in the world has two children the population would neither increase or decrease it would stay the same.
They would have to have three or more children to increase the population. If every couple only has one child the population would decrease. It’s a pyramid affect. But as said this has nothing to do with fertility!

Eh?

So my parents (two people) have four children.
2+4=2??

Now, please correct me, but that looks like a population increase to me unless my parents immediately die after reproducing!

And reproducing has nothing to do with fertility? So infertile couples are capable of having as many children as fertile couples?

I don't know what you're on, but put me down for a kilo!:rolleyes:

Apologies if in post 2 this thread has gone of topic, but even if each couple has 2 children, the population will still fall, as some will be infertile, or choose not to have children. Perhaps not as dramatic as the rate of population growth in the 20th century, but still significant.

From wiki, "The last 100 years have seen a massive fourfold increase in the population".

Doesn't look as if it's declining to me though I accept the rate of increase may be falling. But that is not the same thing as falling numbers.

If numbers are falling, why do they need to buld all these new houses?

I think I'll stick with Sir David Attenborough if you don't mind.

I’m talking in generations and basic maths. And I’m generalising as it’s not a perfect world an some people will have lots of kids and others non, also it wouldn’t be an equil male/female split.

However
If every family have 1 child each and there’s an equal male/female split, then that next generation would half.

If ever family has 2 children 1 male 1 female, the next generation would stay the same.

Like I say this isn’t really anything to do with fertility and is digressing from the subject, it is basic maths though.

Well, I'm talking numbers.

If my flock of 100 ewes had 98 lambs last year and they have 100 this year, that's an increase of 2% but if none died and I didn't sell any I'd have my original flock, plus my lambs, so that's 100+98+100, while you'd only have two!:LOL:

I think your forgetting the death rate in the population. So for example -
you now have two generations, your 100 first generation sheep and 98 lambs, your first generation are now to old and want to retire or the die of old age but your 98 second generation produce 96 lambs so your population initially will increase but over time is on a down slope and eventually wood start to drop dramatically if the trend continued. We’re straying well of topic here again :facepalm:


Ps, to keep it on topic, what if 2% of your lambs are infertile each year? ;)
