Hi Balaji,
Human Resource Management is a very vast field, and people belonging to both genders may equally fit into the HR profile, provided they have the requisite skills and attitude. So, don't let your decision of going for an MBA in HRM or any other stream be colored by such misconceptions; rather, analyze your aptitude for a specific field. I do agree that for recruitments, especially in consulting firms, the fairer sex may get preference, but this is a combination of HR and tele-marketing profiles, and many non-MBAs (both genders) are employed here. On the other hand, I have also seen many job openings where some companies mention "only male candidates/male candidates preferred," especially in IR roles, but that does not mean that females can't handle such matters or are not doing that elsewhere! Moreover, post-completion of your MBA, why limit yourself to the IT-ITES sector and worry about your views on the number of male/female human resource professionals there? HR is not a function that is carried out in these sectors alone; it has wide applications across many sectors.
Hope that gives you some idea about the scope of HRM! However, besides this issue, there are other important factors that you need to consider before zeroing down on the selection of an MBA stream. For example, the number of job opportunities generated is mostly in the marketing field, and the strength of marketing, IT, and finance employees in companies is generally much higher than that of HR. So, fresh MBAs in HR may find it a bit difficult to bag desired HR profiles, whether they are males or females. Thus, check out the quality of education and placement record of the institute thoroughly before taking admission in an MBA and keep working on your skills; the rest will fall into place for sure.
Good luck!
