Why are engineering majors in universities all male?

Here are my personal feelings after seeing the things you said:

1. Lack of gender diversity: an all-male academic department may lead to a lack of gender diversity experiences and experiences for students, which may limit their perspectives and understanding.

2. Lack of female perspectives and contributions: the lack of female student perspectives and contributions may limit discussion and research on topics covered by the department, which may affect the department's academic outcomes.

3. Impact on students' socialization experience: in an academic department with all male students, it may affect students' socialization experience and ability, which may affect their future career development and personal life.

4. Tendency to lead to gender discrimination: in a situation where an academic department is all male, there may be a tendency to be gender discriminatory, which may have an impact on the future career choices and job opportunities for female students.

5. Formation of a male-dominated culture: In an all-male academic department, there may be a male-dominated culture, which may affect students' views and perceptions of gender and social roles.
