The EndoSurvivors International Foundation (ESIF) has said that not less than 40 per cent of the infertility cases are caused by endometriosis.

Stating this during a walk on endometriosis/community outreach to mark Nurses Week in Lagos, organised by ESIF and the National Association of Nigerian Nurses and Midwives (NANNM), the Founder of ESIF, Mrs. Olivia Nwankudu, said the disease was an incurable, invisible, painful disease that affects one in 10 girls and women of reproductive age.
