According to a report by Human Rights Watch, "Since President Ahmadinejad came to power, treatment of detainees has worsened in Evin Prison as well as in detention centers operated clandestinely by the Judiciary, the Ministry of Information, and the Islamic Revolutionary Guard Corps."
Human Rights Watch also has stated, "Respect for basic human rights in Iran, especially freedom of expression and assembly, deteriorated in 2006.
The government routinely tortures and mistreats detained dissidents, including through prolonged solitary confinement."
Human Rights Watch described the source of human rights violations in contemporary Iran as coming from the Judiciary, accountable to Ali Khamenei, and from members directly appointed by Ahmadinejad.

Responses to dissent have varied.
Human Rights Watch writes that "the Ahmadinejad government, in a pronounced shift from the policy under former president Mohammed Khatami, has shown no tolerance for peaceful protests and gatherings."
In December 2006, Ahmadinejad advised officials not to disturb students who engaged in a protest during a speech of his at the Amirkabir University of Technology in Tehran, although speakers at other protests have included among their complaints that there had been a crackdown on dissent at universities since Ahmadinejad was elected.

In April 2007, the Tehran police, which is under Khamenei's supervision, began a crackdown on women with "improper hijab."
This led to criticism from associates of Ahmadinejad.

In 2012, Ahmadinejad claimed that AIDS was created by the West in order to weaken poorer countries, and repeated a previous claim that homosexual Iranians did not exist.
He has also described homosexuality as "ugly".
