Yes, it can. Depends how dramatic the temperature fluctuation is and if it occurs during a critical point in development.

Fluctuation would not cause any problem actually if it's stay btw 27-33°C (or the problem that can happen is about hygro actually), most breeder use variation during incubation for different reason, we sometimes even can make some fluctuations up to 34°C and down to 23°C for a certain time (but those 2 extremes have to be controlled and for a certain time only)...

As JBreptiles said, fluctuation is no big deal as long as it stays in the 78-90 degree F range. Ron tremper even advises that temps be dropped overnight in the incubators. It makes sense if you think about it, these eggs hatch in the wild all the time with temperature fluctuation. The main reason to keep temps stable is to influence gender.

With excess fluctuactions within the safe "viable" range, you won't know if you are going to get males or females. So you will have to sell them as unsexed or you could possibly have to separate males from females when they get older.

Yea, 6 degrees isn't very dramatic. When I incubate anything I let the eggs go through day and night fluctuations, and some species need to go through a special temperature drop to break diapause and then raise it again, so some temp fluctuations are fine. But really dramatic ones (like from 80 down to say, 50) could be very risky.

I do not agree with that actually, sex determination is not an exact science even if we can get very close to get exactly what we want, then IMO nobody should sell a young as unsexed as it's for me too young and too small to afford the stress of new home etc, better to wait until it reach a 15-20g and a visual sexing (also better for your own insurance and satisfaction of customers)
Secondly i will add that the Sex determination is done in a very short time (around the 2nd half of the 2nd third of the incubation, this obviously need hard calcul to know the exact period when the sex will be determinated if you use fluctuation before and /or after the period of sex determination) and the fluctuation is mainly used for influencing the color but not only, it also influence the "receptivity" and "attractivity" of a gecko to another while it come to alk about to breed this gecko later, for exemple it's well known that hot female are more receptive and attracting cold males and vice versa...now we can also indirectly influence it by some variation of temperature during the last part of incubation just after the sex have been determinated...

ron tramper did say after the 23rd day is when the sex has been determined but thank you so much it relived some stress of mine

yes, this is an "average" but if you start incubation at 32.5°C or 26°C, the sex determination will not be at the same time.
