One way to try to keep sperm production intact while on cycle is to use HMG (not just hcg, although hcg have in some studies preserved sperm production for one year, I wouldn't count on it)
HMG contains both LH and FSH which will signal the testicles not only to make testosterone (like hcg does), but to mature sperm.
Another theoretical way of keeping sperm production is to make sure you have it intact when you start the cycle, and the use a megadose of testosterone.
While this might be better for sperm production (in theory),it's not a viable option IMO. The reasoning behind it is that testosterone alone seems to be able to keep up sperm production, but testicles normally have a 100x higher concentration than the rest of the body. So even using 500mg T a week will actually "starve" your testicles of T. But that's a bit off topic, as it's not really an option IMO.
Best thing to do, if possible, is to freeze down sperm (or be done with children) before one begins to cycle. That's fool proof.
Second way is to utilize hcg and be able to recover after cycle.
HMG is more expensive than hcg, but using that instead of hcg will almost guarantee sperm production.
