Where's the fertility???

Wow, so you guys think his sperm could be dying from the high temps on the hot spot? That's crazy, I never thought about anything like that. I guess I just figured since he had proven before he could do it again so I blamed the girls... I added a bunch of layers of paper towels underneath the repti-carpet to lower the temp on the hot side of his cage...I guess we'll see with the next clutches...and if that's not the problem i'm taking up Burger King on their night manager position.

I don't know if the sperm is dying but I always keep the breeder's tubs at 90f on the hot side.

The male is 2 years old, kept separate, and is introduced only for breeding purposes...
The temps on the hot side go from 95-97 degrees...the cool side goes from 75-80 degrees...the temps are the same as they always have been. The proven female continues to lay her slugs in the moist hide (as I believe this comes from last years experiance) and the new breeder seems to just lay HER slugs wherever she is at the time.

He has NOT proven this year, again I am puzzled as to why his "parts" would just "work one year but not the next" if nothing has changed on my end...? I'm so frusterated, i'm almost at the point of just investing in a new breeding pair.

I'm not saying it is because of the temperature, although that could be at play. There's no evidence so far to determine a cause at all. There is some evidence to determine the general condition, however, which has been a component of my point, of which the primary component is that, if you have three geckos today, and the common link between two "infertile" females is one male, then the probability of it being the male is a far more parsimonious explanation and is more likely than two separate females that are placed with him both having a similar abnormal condition. Now, it still could be the females, but I said originally that I'd go with math and consider the male as the potential culprit first.

Let's look at this differently. Would you be puzzled if a human could conceive one year and not the next? Would you be puzzled if a human's eyesight was at 20/20 on year 6 and mild myopia creeps in at year 7? Things sometimes change.

I would lower the temps to around a 90 degree hot spot and wait about a month, if it is the males sperm this is plenty of time for him to regrow some viable gametes, then see if the females conceive and produce good fertile eggs. I had a friend who had this same problem earlier this year and is now getting lots of fertile eggs and hatchlings. So give it a try and let us know how it turns out. :main_thumbsup:

One of my girls is a bright orange gorgeous Hypo Tang Albino het Raptor I bred to my SHTCT het Raptor male and she takes ONE MONTH between clutches and every egg has been a dud. I am looking forward to their eggs more than any other pair and it looks like its not happening.

I think you are probably not doing anything wrong, hopefully the temp thing works out!! Good luck to you!
