“How to conceive twins” and “how twins are formed” are some most wondered questions during pregnancy. Some say they are two unique souls united together. What do you think?
What’s the most interesting thing you feel about the human body, or more specifically about human birth? Everything about human pregnancy is mesmerising, but there’s something so much more phenomenal about conceiving twins. If you have ever pondered how twins are formed or want to know how to conceive twins, this blog is going to answer all the important questions.
We would advise against closing the tab, or you might miss some most interesting facts about how twins are formed and how to conceive twins!
Basic Of Twins & Their Types
First and foremost, let us tell you about the basics of twins before moving to how twins are formed. There are two types of twins, the Monozygotic twins and the Dizygotic twins. Yes, not all twins are identical and share common neurons. Everyone wanting to know how to conceive twins should first be aware of these simple biological facts. There are two types of twins, categorised on the basis of eggs involved; mono means one egg, and di means two eggs are involved.
Monozygotic Twins
Have you ever come across identical twins? You can also call them monozygotic twins. As we have already told before, monozygotic twins are formed with only one single egg. But how twins are formed? They are formed when one single egg is fertilised by one single sperm. Then, due to conditions, this resulting zygote (the fertilised egg) gets split into two at a very early stage of development, leading to two separate embryo formations. When you thought of the question “how to conceive twins?” was this thorough of the possibility? The rate of conceiving monozygotic twins is 4 per 1000 pregnancies, which is 0.004%, which results in a live birth. Thus it’s a sheer miracle to conceive twins at all.
Now, monozygotic twins are further classified into two categories based on their development; the identical twins and the conjoined twins.
Identical Twins
The identical twins occur when the zygote is completely separated, thus resulting in two separate embryos leaving in their wake. These twins share all the same genetic information virtually until they are later separated. There are some interesting facts about twins that everyone must know about, like they can be born years apart.
Conjoined Twins
The conjoined twins, on the other hand, are formed when the monozygotic is separated into two but conjoined from one tissue or organ. The probability of conceiving conjoined twins is even rarer than identical twins, about 1 in 100,000 pregnancies. There are possible reasons for how twins are formed, either the zygote is split prematurely and incompletely, or two separated embryos are joined back together later during pregnancy.
Though the location where twins are joined can vary, from head to toe, and some twins can also be operated apart. The below-shown picture is an example of two conjoined girls from their torsos.

Dizygotic Twins
How dizygotic twins are formed is a different story. Unlike monozygotic, two separate eggs are fertilised by different sperms, mostly at separate times. However weird and fascinating it seems, it’s actually twice probable to conceive dizygotic twins than monozygotic twins. Still confused about how twins are formed? During a whole cycle (that is, from the start of the first period to the beginning of the second period) of a woman, her body produces eggs; when two eggs are each fertilised by different sperms during the same cycle and results in twins, this phenomenon is called Dizygotic twins.
There are several factors that determine the probability of conceiving twins, like hyperovulation in a dizygotic twin’s case.
Factors That Are responsible for Twins Conceiving probability
Want to know how to conceive twins? Here’s how, while learning about how to conceive twins and how twins are formed, you must understand that there is not one but several factors steering the possibility of twin formation. If you want to know
Family History
If you want to know how to conceive twins and what your chances are of conceiving them, looking into family history is the first thing you should do. If you have a family history of having twins on your father’s side, that’s good, but if your mother’s side is blessed with twins, then you are into the race. The chances of having twins for non-identical twins (men) is 1 in 125 births, whereas conceiving twins for non–identical twins (women) is 1 in 60 births.

Fertility Treatment
The researches and studies have shown that fertility treatments can be the main factor that can increase the chances of conceiving twins. There are various types of fertility treatments, like fertility drugs and IVF, etc., that can stimulate a woman’s ovaries, resulting in producing more eggs and thus increasing the chances of conceiving twins.
Age
The study suspects that if you are a woman over 30, the chance of conceiving twins is higher for you than younger girls. If you are fascinated by how twins are formed and want to know how to conceive twins, you have higher chances. After 30, a woman’s body is likely to produce more than one egg during one cycle.
Height & Weight
Though this is not certain, it’s found in reports that women conceiving twins for a taller and heavier woman is slightly more probable than in smaller and petite women. The reasoning behind this is still not clear yet, but it’s suspected by the experts for their better nutrition.
Final Words!
We hope you thoroughly enjoyed the blog and found it the answer to your turmoils. And about how to conceive twins, we are obliged to clarify again that it’s but a natural process and no scientific progress has been made to confirm the formation of twins for sure. So stay clear of any such temptation and follow the course of nature.
