In 2006, Ahmadinejad's government applied a 50 percent quota for male students and 50 percent for female students in the university entrance exam for medicine, dentistry and pharmacy. The plan was supposed to stop the growing presence of female students in the universities. In a response to critics, Iranian minister of health and medical education, Kamran Bagheri Lankarani argued that there are not enough facilities such as dormitories for female students. Masoud Salehi, president of Zahedan University said that presence of women generates some problems with transportation. Also, Ebrahim Mekaniki, president of Babol University of Medical Sciences, stated that an increase in the presence of women will make it difficult to distribute facilities in a suitable manner. Bagher Larijani, the president of Tehran University of Medical Sciences made similar remarks. According to Rooz Online, the quotas lack a legal foundation and are justified as support for "family" and "religion."
