When there is more semen than sperm, getting past the cervix is clearly a problem, since most sperm is in the first few drops of ejaculate. Men with poor sperm volume or viscosity are encouraged to withdraw from the vagina just after ejaculation starts. Or they may withdraw prior to ejaculation, collect their semen, and drop it off to a lab for the artificial insemination procedure.
Spun-glass fibers are put into a syringe with the sperm, where the sperm are required to pass through the fibers. In theory, the dead sperm should stick to the filter and not make it through. This is a highly experimental procedure with unconfirmed success rates thus far.
Washing is a now a standard procedure in any IVF/GIFT-like procedure. The sperm are separated from the semen by being spun in what is called a centrifuge. This removes the proteins and enzymes that protect the sperm's head, enabling it to enter the petri dish or fallopian tube fully capacitated.

Chorionic gonadotropin is not normally used alone as a fertility drug -- it is normally administered after administration of menotropins or urofollitropin.
