Luck. There is no way of having identical twins, let alone choosing the sex.

There are two primary types of twins, Identical and Fraternal.

Identical twins occur when the egg splits after fertilization. To date no indication of a genetic link has been found. Anyone has a chance, though small, of having identical twins.

Fraternal twins occur when more than one egg is dropped during ovulation. This trait can be inherited from the mother's side of the family. Studies have shown that the chances are also increased by being overweight or older. Fertility drugs also make this more likely to happen.

How are identical and non-identical twins formed?

There are two two kinds of twins.Gametic twins - two sperms fuse with two eggs to form gametic twins.In the case of gametic twins, the twins are not identicaland infact there is a chance for one male and another female.Zygotic twins - zygote forms after fertilisation (Fusion of sperm and egg). The zygote divides in to two cell and these two new cells develops in to twins.In the case of zygotic twins, the babies are identicaland both the twins will be males or females.

Can conjoined twins be male and female?

No. Conjoined twins are always identical twins, and never just fraternal twins. Identical twins come from a single embryo that splits. In the case of conjoined twins, a complete split never occurs. So when they come from the same embryo, they are always the same gender.

Are conjoined twins always the same sex?

Yes. Conjoined twins are always identical (monozygotic) twins, and identical twins are always the same sex.There is a theoretical case where identical twins could be opposite genders, when the babies are female but in one of the females, a branch of one X chromosome breaks away; however, I don't believe this has ever been observed.
