Who are more likely to have conjoined twins?

Conjoined twins occur due to incomplete separation of the zygote during fetal development. While anyone can have conjoined twins, certain factors increase the likelihood:

- Race: Conjoined twins are more prevalent among certain ethnic groups, specifically in West Africa, South Asia, and Southeast Asia.

- Family History: There seems to be a genetic component involved, as conjoined twins are more common in families with a history of the condition.

- Maternal Age: Advanced maternal age has been associated with a slightly increased risk of conjoined twins.

- In Vitro Fertilization (IVF): IVF has a small but increased association with conjoined twins, likely due to the hormonal manipulation involved.
