Confused about lowering sperm count...

[Trike3]

I'm so sorry if this is a stupid question, but I'm confused and can't se to fond an answer I understand by using the search option...

How exactly would lowering sperm count sway pink? What's the theory behind that? I'm thinking of using spermicide in my sway, because I've read on here that it is a good way to lower sperm count.
I'm confused though, because it seems to me that if sperm concentration is 50/50 xx/xy, wouldn't things like spermicide just reduce both, not one more than the other? Is this based on the idea that XX sperm are heartier? I thought that was debunked? Or am I just confusing things?

We don't know why! There is no theory to my knowledge.

For some reason we do not know, everything that lowers sperm health and quality and numbers, both before and after they leave DH's body, seems to sway pink. We don't know why. I have my own theories, including that there is some primitive communication between X and Y sperm and that if there are a lot of them, the Y capacitates while the X stays dormant, or that the slightly different size of the X vs. Y may confer some benefit between the two when it comes time to fertilize an egg (it may be a slightly larger cell can get through the egg shell with less help than a slightly smaller one, since it takes many more than one sperm to fertilize the egg). But it's just speculation, we don't know.

I thought it only took one sperm to fertilize the egg? Or do you mean this is the grander sense...

One sperm can't make it through the eggshell alone. It takes several working in concert.

Also forgot to mention in the above reply that there is a new study that indicates conditions in the Fallopian tubes may change to favor X vs. Y and we don't know why that happens, it may be that sperm numbers has something to do with that.
