Male Royal Python Ready to Breed Before Female?

At the moment I have a male ball python that is ready to breed although, my female is still too young and nowhere near the correct breeding weight of 1500g. After conducting much research online and talking to various breeders I have discovered that it's important not to let males get overweight, especially if one is looking to produce good fertile eggs.

At present moment in time, my male is sitting at 700g. This means that he is ready to breed and putting on weight rapidly. This is a bit of a problem as my female needs to wait at least another two years before I could consider breeding. This poses a problem as males can become more lazy and not produce good quality sperm when over 1200g.

This means that I will have to either purchase a female that is breeding weight or change the feeding routine of the male. Due to lack of space I have decided to opt for a different feeding routine. When the male reaches 1000g I will switch to a smaller size feeding item every second week whilst keeping the normal size prey. By doing so, I hope to achieve a balanced weight of around 1100g without it declining or increasing majorly. Furthermore, if he does fast there is plenty of fat reserves to sustain him for a good few months as we all know royal pythons can be picky!
