Young kittens are very difficult to correctly sex. The genitals only start to visibly develop once the kitten is at least two or three weeks old.
The best way to tell what gender a cat is, it by looking underneath the base of its tail. A male cat that has not been neutered will have two furry testicles right below the anus, and a penis right below the testicles. A neutered male cat will not have visible testicles, but there will be a noticeable space between its anus and penis.
Spayed and intact female cats alike will have a genital opening (vulva) which is a tear-drop shape located right below the anus.
By physical examination. The distance between the urethra and the anus is further in males. The male kitten will appear bulkier right below the anus since that is there the testes are. The shape of the urinary opening is different too, since it is more circular in males and more like a slit in females.
Though not reliable, color can sometimes be used as a gender indicator, since tortoiseshell cats are nearly always female, while ginger cats are more likely to be male.
It is rather difficult to view the gender of a newborn kitten and is best to check between 6-8 weeks of age. At that time you can measure the distance between the anus and vulva (and penile hole). Female kittens anus is closer to the vulva than a males to his penile hole. Also, on females it is rather flat where as in males there may be a sac.
If it's got a little Wee-Wee it's probably a male.
Here is a website that should help http://www.pawsonline.info/sexinga.htm
By looking below the anus for either a vulva or a scrotum. Because the genitalia can be quite small at that age, it can take some experience to get good at determining the sex of kittens.

the sonologist can tell you about 12 weeks into your pregnancy at an ultrasound.
At 16 weeks it is 80-90% accurate using an ultrasound
