Only Female Guppies

About three months ago I adopted three guppies. They are in a 10G and the first time they gave birth I got really exited but when I later checked (it was about two months later) all the guppies where female and this happens me many times. My fish have never given birth to a male baby

All young fry appear to be females. After about a month you can start telling them apart. If you post pictures perhaps we can help sex them for you, I'm sure the 100s of fry you must have by now can't all be female.

 

They are all adults now and I had RainBetta check them and she said that there where no males I am currently on vacation but when I get back I will post pictures

Actually they are. I've heard that having a lower ph can affect the gender of fry, but I think it's completely odd that EVERY Single baby is female. More than half are fully grown by now, and they are very clearly females

Ph, temperature, any other water parameters that are said to affect gender are all nonsense. The gender is determined by its genes, and fish embryos do not change genders because the water is hard or acidic.

Most likely they simply haven't developed enough to determine their genders yet or perhaps the males that have developed are clamping and therefore making it more difficult to identify them.
