I read something a while ago about test cyp being used as birth controls on males, given at low doses. Something like 97% effective, similar statistics to female birth control..
I couldnt find the same information again, but what do you guys think? Anyone gotten a girl prego well into a test cycle?

The research would suggest several other options are possible. Studies show that the right combinations of testosterone and a progestin can successfully and reversibly suppress sperm production in most men. Though a combination oral birth control pill wouldn't work — the necessary testosterone would get broken down too quickly in the liver — researchers have developed several other delivery methods: monthly injections, creams and twice-a-year synthetic implants into the arm. None of these birth control methods are as convenient or noninvasive as the Pill for women, but they are as safe and as reversible.
The only problem is that they're not always as reliable. In men who respond to them, hormonal contraceptive treatments have been shown to be 100% effective in clinical trials. But studies have also shown that 10% to 15% of men don't respond to hormonal treatments at all — a fairly high nonresponder rate. Researchers don't yet know how to explain those failures. One inherent stumbling block is that a male contraceptive must block millions of sperm, as opposed to a single egg. (The Pill had it easy.) Another is race: according to several proof-of-concept studies, Asian men maintained a suppressed sperm count with greater frequency than Caucasians, but researchers still don't know why.
