Women have to get permission from their husbands to travel abroad. They are obliged to cover their hair and the shape of their bodies, their testimony as a legal witness is worth half that of a man, and daughters inherit half of what sons do.
While they cannot run for president, they are however able to hold most jobs including other government positions, and can vote and drive.
"What will change if I vote?" said Miriam, 26, who could not win custody of her eight-year-old son after getting divorced in the central city of Isfahan. "Can reformist candidates give me equal rights?"
A report by the United Nations (UN) special rapporteur on Iran last year said human rights in the country "remained dire" under Rouhani, while separately a UN child rights watchdog said this month that girls faced discriminatory treatment "in family relations, criminal justice system, property rights".
Iran denies any infringement of human rights.
Retired government employee Fariba Khamesi, from Tehran, said that even if there had been little evidence of social change, she would not give up her hopes for a freer Iran.
"Of course I will vote in the elections. There are many problems like the economic pressure, discriminatory laws against women, but if we don't cast our vote, conservatives will gain more power," the 58-year-old said.
'Pain and problems'
Rouhani's hardline rivals accuse him of having encouraged moral corruption in the society by advocating social tolerance.
Moderate politicians remain faithful to Iran's theocratic system, but they advocate improved relations with the West, more freedom of expression and a loosening of strict 'religious' rules governing dress and mingling between the sexes.
"As an Iranian female candidate it is my duty to fight for their rights," said Soheila Jelodarzadeh, a pro-reform female candidate. "Women are determined to build Iran. And by casting our votes, we can reach that goal."
International sanctions were lifted last month under a deal reached with six major powers in 2015 in return for Tehran curbing its nuclear programme, but it will take time to bring down high unemployment and raise living standards.
