In a rare medical precedent, American Tilma Chayaka gave birth to six children in just nine minutes. "The Woman's Hospital of Texas" published the news that one Texas woman had two daughters and four children. Newborns weigh between 800 and 1,300 grams.

Doctors at the obstetric hospital confirmed that the birth rate was very good despite the pregnancy and birth of six children at once. Chayaka has already named her two children, Zina and Zorel, as she had previously planned, and her children have not yet been named.

According to statistics from the Texas Hospital, the birth rate of six twins is one in 4.7 billion births.
