Sperm Tests

[Zaphod]

About seven years ago I fathered my son three months after starting trying with my Ex wife.

Last summer I helped a woman get pregnant by AI, that took two months

Just before Christmas my GF went from on the pill to up the duff in three weeks

However last summer my Dr said that my sperm contained white cells and did not look that clever.

Now, either I'm just damm lucky, the ladier are hyper fertile (Well, the ex wife has PCOS, the Girlfriend is 39..................) or the tests are not up to much.

Anyome else had any similar experiences?
