Thank you for your question. It is an honor to be of some assistance to you.
There is no guaranteed method for conceiving fraternal twins. The frequency of twins depends on the type of twins. Identical twins occur about once in every 250 births around the world. This type of twin formation appears to be uninfluenced by age, race, heredity, number of pregnancies
or medications taken for infertility (fertility drugs). The incidence of fraternal twins is influenced by race, heredity, maternal age, the number of previous pregnancies and the use of fertility drugs.
The frequency of multiple fetuses
varies significantly among different races. Twins occur in 1 out of every 100 pregnancies in white women compared to 1 out of every 79 pregnancies in black women.
The use of Clomiphene Citrate (Clomid) will increase your chance of conceiving twins to about 1 in 10. The chance of triplets using clomid is very low.
I hope you find this information helpful. Please, do not hesitate to ask me any questions in the future or to request me. Remember, this communication does not replace a visit to the doctor.
