How does it happen?
In general, ovulation in women gets restricted right after she conceives, and reopens only after the prevailing pregnancy cycle gets a closure. Also, certain hormonal changes do not allow another embryo to develop. But in some rare cases, ovulation remains open for few days after women conceive. If, during this period (within 10 days), such women have sexual intercourse, then there is a possibility of the occurrence of another foetus and its development. It is more like additional ovulation, explained Dr Ru Sehra, senior consultant, gynaecology, Sri Balaji Action Medical Institute.
Agreed Dr Surabhi Siddhartha, consultant obstetrician and gynaecolog, Motherhood Hospital Kharghar and said that in such cases, two sperms fertilise with the ova. Having intercourse after pregnancy test is positive in the ovulation cycle can lead to such cases, and there is no way to prevent this condition.

She added, “Usually, the thin layer of the endometrial line doesn’t let another foetus enter the already developing embryo, but in rare cases, it successfully penetrates through it and starts developing. Hence children born out of such condition are twins but not identical.”

Is there any risk to mother or child?
Although this is a rarest of a rare condition, which hardly involves any risk for the mother, there is a high risk of having a premature ba, according to Dr Sehra. It may be due to the fact that while one ba may be ready to be born, the other one might be at the developing stage in the womb.
What measures can one follow?
“Opt for a safer pregnancy. This means that supportive medications owing to both pregnancies need to be taken and the woman should be closely monitored because of the double weight of the pregnancies,” explained Dr Surabhi. Especially, couples choosing to be parents through surrogacy should be more aware of its safe procedure,” mentioned Dr Sehra.
