Because that is what a female Somali activist said in a video on youtube and that is what it says in this report

Women are in particular confronted with barriers in access to health services due to their status in the family when they are in need of major surgical interventions, including emergency obstetric care and other sexual and reproductive health needs. According to UNFPA, married women need the consent of a male relative (or in some cases the mother in law) before a doctor will perform a lifesaving intervention at any public or private hospital (e.g. a caesarean section). This is not only a matter of securing the financial means to pay for the procedures and the required medical supplies, but according to UNFPA a matter of ensuring that the family agrees with the intervention and possible negative outcomes. If the doctor does not ensure male consent, he might run the risk of repercussions after the intervention. A ten year old example was cited where a doctor had saved a woman’s life by performing an emergency caesarean section which had included the removal of the uterus without having had time to obtain consent from the family. The family was upset by the fact that the woman had become infertile and the doctor had to leave the country. Furthermore, unmarried, young women may not access family planning or sexual health services of any kind unless accompanied by their mother or father. Male consent as a barrier for women’s free access to health services is being recognised and addressed by advocacy activities but so far no bill or law, act or decree has been put in place.
