North Korean authorities have been punishing doctors who carry out abortions and the providers of contraceptives amid a drive by the country to boost its birthrate, according to a recent report.

Radio Free Asia (RFA) cited a medical field source in the northern province of Ryanggang, which borders China, in its article. The source, who requested anonymity for their own safety, said the head of the obstetrics and gynecology department of Paegam County Hospital was put on trial for having conducted at-home abortions.

The doctor, who conducted one abortion at home that resulted in the death of a woman, was sentenced to five years in prison, according to RFA. His trial was held in a conference room at a medical university hospital.

North Korea’s fertility rate, or the number of babies expected per woman’s lifetime, dropped to 1.8 births per woman last year, according to estimates by the United Nations Population Fund. A fertility rate of 2.1 is considered the minimum rate necessary for a population to sustain itself over time.
