It depends on many factors, including the type of conjoinment, the ability to reproduce, and the potential danger to the twins, if female. I would think that for dicephalus female twins, they could have children, if their health permitted. If female twins were born sharing reproductive organs facing one another, having children might be physically prohibitive. Completeness and functionality of reproductive organs may be the most important factor in reproduction for conjoined twins.
If the twins were born joined at the top of their skulls, or lower abdomen, reproduction may be prohibitive, for many reasons. Obviously, copulation could prove to be quite difficult, especially for those twins joined at the pelvis, with their heads at opposite ends of conjoinment. Being born facing one another, especially at the chest or abdomen, may very well prove daunting for reproduction. I would think their bodies would prevent growth of a fetus, even if they consented to one of the twins attempting copulation with a non-conjoined male.
Degrees and types of conjoinment are quite various, as one will discover through online research. For some twins, copulation, gestation, and childbirth may be nearly as practical as non-conjoined mothers-to-be. Consider that in a case where female twins are joined closely, as dicephalus types, the physical act of reproduction may seem easy enough to complete. If a male were to desire sexual intercourse with a female joined to her sister back-to-back, i.e. the lower spinal region, can he do so without offending the twin of his lover? The possibilities are quite varied, do to a plethora of reasons.
I have wondered, like many others, what it would be like to have relations with attractive conjoined women. Would marriage be legal and practical? I would imagine that both twins would enjoy the sensations and climax associated with sexual intercourse. Could sex with my conjoined partner be possible without guilt? What if she and her twin each had two arms, but only one pelvis and two legs? Fascinating, yet very strange, to imagine myself copulating with a woman born in such a way. Since they are literally two women, yet joined together, I would have to be understanding if my conjoined wife's sister wanted a husband of her own. Would that be very difficult to accept, especially if my wife was a dicephalus twin? I could postulate and speculate for a very long time. Rosa and Josepha Blazek were conjoined twins, one of whom - Rosa - had a son.
Conjoined twins cannot be bred. This condition is not genetic.A set of male conjoined twins fathering children with a set of female conjoined twins will almost certainly produce children who are not even twins at all.
Conjoined children can be connected at any body part. So yes, they can be conjoined by testicles.
The most famous (Chinese) conjoined twins were the Siamese twins

Dr. C. Everett Koop was the first surgeon to successfully separate conjoined twins in 1956. The twins were conjoined at the abdomen and were named Patrick and Benjamin Binder. The surgery was performed at the Children's Hospital of Philadelphia.
The twins were conjoined when they were born.
There is Identical twins, Nonidentical twins and Conjoined twins.
Craniopagus twins are conjoined twins who are attached at the head.
Just that, female conjoined twins. In some languages all nouns have gender, so in French, Les Jumelles Siamesienne, the enne suffix would mean female. By the way, conjoined twins, being also identical twins, are always the same gender.
