BLOOD CLOT FACTOR
Gen 17.12 – … From now on you must circumcise every baby boy when he is eight days old…
God specifically tells Abraham to circumcise all infant males on the eighth day.
According to professor H. Dam, in 1935, proposed that vitamin K was the factor in foods that helped prevent hemorrhaging in baby chicks. Vitamin K is responsible for the production of prothrombin.
Between the fifth and seventh days of the newborn’s life vitamin K which Is produced by bacteria in the intestinal tract is present in high quantities. Vitamin K along with prothrombin causes blood coagulation which is crucial in all surgical procedure.
Pediatricians have recognized over the past century that newborns are highly susceptible to bleeding between the second and fifth days of life, which can cause hemorrhage usually inconsequential sometimes it can be quite extensive, producing serious damage to internal organs such as the brain or even cause death from shock and exsanguination (blood loss).
On the eighth day prothrombin present in infants elevates over 100% of the normal amount. This being the only day in a males life this occurs. Thus if surgery is to be performed, this is the perfect time to accomplish this.
