Fiona Bruce MP had tabled an amendment to the Serious Crime Bill underlining that 'gender abortion' is against the law.
Currently the legislation does not make clear whether it is legal to terminate a baby because of its sex.
A similar bill has already had an initial vote in November when MPs backed Fiona Bruce's Abortion (Sex-Selection) Bill, but this did not have enough time to become law before the election.
A yes vote yesterday would have seen the law changed to reflect that abortion because of a baby's gender is illegal.
Ms Bruce said she hoped it would "eradicate any confusion that there might be about this issue."
Speaking to Premier in November the Bishop of Norwich, Rt Revd Graham James, said it was 'sad' the law needed to be clarified.
He said: "So many parents who perhaps didn't want a boy or a girl, or they didn't expect to have a child who had Down Syndrome grow to love that child and to be changed by that child."
The Bishop added that children were "not a commodity to be purchased".
Currently the organisation Christian Concern is taking private legal action against a doctor which it accuses of carrying out terminations on the grounds of gender.
Dr Prabha Sivaraman, 46, was filmed by an undercover journalist allegedly planning a termination based on the sex of the unborn baby.
The police had investigated Dr Sivaraman in 2012 but the Crown Prosecution Service decided not to press charges because it wasn't in the public interest.
Christian Concern is now supporting a private prosecution.
In a statement about the proposals the British Pregnancy Advisory Service said: "If any woman was however under pressure to terminate her pregnancy on the basis of the sex of her baby, her needs would certainly not be served if she felt she was unable to divulge this fact.
"Any woman who feels she is being forced to end a pregnancy she wants to continue needs to be able to discuss in confidence what is happening.
"In this way appropriate help and support can be provided so that she can make the right decision for her.
"Women need to feel they can speak freely to staff about their reasons for requesting an abortion, and legislation which seeks to effectively criminalise these discussions could potentially make their situation much worse."
