Soon, things start to get out and Tripti gets a paternity test done to understand the baby’s birth father. It turns out that both Vicky Kaushal and Amy Virk are the fathers. When this leads to further confusion, the doctor clarifies that it is a rare case of heteroparental superfecundation.

The trailer depicts the rare phenomenon of a child being born with two fathers. After the trailer was released, the term heteroparental superfecundation has peaked the interest of netizens.
What is heteroparental superfecundation?
This is a rare process in which two eggs from the same menstrual cycle are fertilized by different sexual intercourses. Due to separate sexual intercourses with two different partners, the eggs are fertilized by different sperms, resulting in twins who do not have the same father – rather, they have different fathers. This phenomenon is extremely rare and is an interesting biological process.
How rare is heteroparental superfecundation?
This is an extremely rare process. To date, only 19 cases of heteroparental superfecundation have been reported. However, the process is more common in cows. Cows are not as monogamous as humans, and heteroparental superfecundation occurs more naturally and frequently to them.
In humans, heteroparental superfecundation is possible when two episodes of sexual intercourse occur with two different partners with a very short time gap between them. The term superfecundation originates from the word fecund. It means the ability to produce offspring.
On the other hand, homoparental superfecundation is a process in which two eggs are fertilized by the same sperm, producing fraternal twins. In the case of heteroparental superfecundation, the twins are half-siblings who have the same mother but no father.
How does heteroparental superfecundation occur?
Sperm cells can survive for up to five days inside the female body. Once ovulation occurs, the egg remains viable for about two days before it disintegrates. After the first episode of fertilization of the egg, superfecundation is possible within a few hours or days. However, after the female becomes pregnant during the first ovulation, if the egg is released, there is a possibility of a second pregnancy. This process is also called superfetation.
Bad Newz, directed by Anand Tiwari, addresses this rare phenomenon. The comedy drama stars Tripti Dimri, Vicky Kaushal and Amy Virk in lead roles. The film is set to release on July 19.
