The incident comes against the backdrop of a raging debate on lack of scrutiny of the curriculum and content taught in schools.
The book titled "Health and Physical Education" written by Dr VK Sharma and published by Delhi-based New Saraswati House, is taught at various schools affiliated to CBSE.
While CBSE only recommends books published by the National Council of Education Research and Training (NCERT), certain books from private publishers are also taught in schools affiliated to it.
Various Twitter users shared picture of the mentioned text and demanded that the publishers withdraw the content and schools replace the book in their curriculum.

This, however, is not the first incident about improper content being found in textbooks taught in CBSE schools in recent months.
In another recent incident, a class XII Sociology book cited "ugliness" and physical disability of a girl as reasons behind the dowry issue prevalent in the country.
The HRD Ministry had last month said that CBSE has no mechanism to evaluate the quality of textbooks of private publishers.

The Central Board of Secondary Education (CBSE) has no mandate to prescribe or recommend the textbooks of private publishers in its affiliated schools," Minister of State for HRD Upendra Kushwaha had said in response to a written question in Lok Sabha.
