As the commissioner for women affairs and social welfare in Anambra state, Ify Obinabo has plenty of experience in resolving family disputes - but this is no ordinary disagreement.

Five members of Ike’s family, who are also present in the room, do not believe Hope is the couple’s biological child, as Chioma and Ike claim.

Chioma claims to have “carried” the child for about 15 months. The commissioner and Ike’s family are in disbelief at the absurdity of the claim.

Nigeria has one of the highest birth rates in the world, with women often facing social pressure to conceive and even ostracisation or abuse if they cannot.

Under this pressure, some women go to extremes to realise their dream of motherhood.

For over a year, BBC Africa Eye has been investigating the “cryptic pregnancy” scam.

Scammers posing as doctors or nurses convince women that they have a “miracle fertility treatment” guaranteed to get them pregnant. The initial “treatment” usually costs hundreds of dollars and consists of an injection, a drink, or a substance inserted into the vagina.

None of the women or officials we spoke to during our investigation know for sure what is in these drugs. But some women have told us they led to changes in their bodies - such as swollen stomachs - which further convinced them they were pregnant.

Women given the “treatment” are warned not to visit any conventional doctors or hospitals, as no scan or pregnancy test would detect “the baby”, which the scammers claim is growing outside the womb.

When it’s time to “deliver” the baby, women are told labour will only begin once they are induced with a “rare and expensive drug”, requiring further payment.

Accounts of how the “delivery” happens vary, but all are disturbing. Some are sedated only to wake up with a Caesarean-like incision mark. Others say they are given an injection that causes a drowsy, hallucinatory state in which they believe they’re giving birth.

Either way, the women end up with babies they are supposed to have given birth to.

…

The extent to which the women involved genuinely believe the claims is unclear.

But clues as to why they would be susceptible to such brazen lies can, in part, be found in online groups where disinformation around pregnancy is widespread.
