|  | Regular Member | Join Date: Sep-06 Location: Coventry Age/Gender: 39  | | | quick question regarding sperm retention
Have any of you guys documented sperm retention in carpet pythons ...?
has any one got any information at all on this subject please help me out here ?
im asking as i have a clutch of jungles and one odball that appears Jaguar ..
now the last time the female seen the jaguar was oct 06 could this happen after all this time
i always thought that new sperm would simply be used and any retained would be disregarded
could it survive that length of time in the female ?
Any advice will be greatly appreciated
Help me out here guys
Cheers
Steve

I know it has been documented at 12 month's in Blood pythons, but haven't heard of the time scales associated with carpets, I would imagine it is quite possible though.

I would of said unlikely, but that is very interesting indeed, the truth of the matter is that the answer you seek is not conclusively proven either way. I know of cases of antaresia producing fertile clutches without being with males for 18 months prior.
Most evidence is hearsay rather than scientific! I wouldn't say impossible who knows! Quote:

I've never seen any written documentation, but I have heard from different sources that a female can hold sperm for up to two years. That's all I've heard though. I wouldn't have a clue if it true, and even if it were true, I couldn't say weather the retained sperm could fertalise an egg along side new sperm. Sorry Steve, but I will see what I can find out for you though.
Cheers,
Nic.

Female pythons can definately retain viable fertile sperm from copulations atleast 2 to 3 months before ovulation .
I have had a example of this happening from a female jungle carpet python aged 2 and half years old that produced a clutch of 8 eggs from 2 mating opertunities 8 to 10 weeks before i observed ovulation .
No further mating introductions were made because the female did not appear to be growing follicals and i was focused on introducing the breeder male to my other 3 breeding females at the time .
All 8 eggs are appeared fertile but i did not candle them.
Anyway 6 healthy hatchlings emerged from the clutch
proving the female stored sperm from those copulations at that time .
Steve
I do beleive the Jag looking neonate you hatched from your jungle clutch is the result of a stored sperm from the previous years copulations and a couple of the other hatchies look like jag sibs with reduced head patterns etc
cheers
