Iran’s legal system criminalizes most sexual activity outside heterosexual marriage, yet the private reality of sex in the country is far more complex than the law suggests. Premarital relationships are widespread among young Iranians, cohabitation without marriage is on the rise, and institutions like temporary marriage blur the boundary between religious permissibility and social stigma. The tension between a theocratic legal code rooted in Shia jurisprudence and a rapidly modernizing, heavily urbanized young population makes Iran one of the most contradictory places on earth when it comes to sexuality.
What the Law Says
Under Iranian law, the only recognized sexual relationship is one that occurs within marriage. Sex outside marriage, termed zina in Islamic legal vocabulary, is criminalized and can theoretically carry severe punishments. Rape is classified in Iranian legal language as “adultery with force and duress” and falls under the broader category of zina, which means it is treated as a subcategory of sex outside marriage rather than as a distinct crime of violence. The law does not recognize marital rape as a criminal offense.1ScienceDirect (Elsevier) / Women’s Studies International Forum. Standing on top of society’s sexist load: Gate-keeping activism and feminist respectability politics in the case of the Iranian MeToo Movement
Same-sex sexual acts between men are also criminalized under the penal code. Iran’s 2013 penal code draws a distinction between sexual partners based on their physical role during intercourse, with the penetrated partner facing harsher punishment than the penetrating one.2Punishment & Society. Dangerous positions: Male homosexuality in the new penal code of Iran This counter-intuitive asymmetry reflects how the law encodes ideas about masculinity and sexual passivity rather than treating same-sex contact as a single offense. For women, same-sex acts carry different, generally less severe, legal provisions, though they remain illegal.
In practice, enforcement is inconsistent. Iran does not have a functioning morality police that monitors every bedroom. Most prosecutions for sexual offenses arise from public complaints, family disputes, or political targeting rather than from active surveillance of private conduct. That said, the legal threat hangs over every private decision, shaping how Iranians talk about, conceal, and navigate their sexual lives.
Temporary Marriage as a Legal Workaround
One institution that straddles the gap between law and desire is mut’ah, or temporary marriage, known colloquially in Iran as sigheh. In Shia jurisprudence, a man and a woman can enter a marriage contract for a fixed period, from an hour to several years, with a specified dowry. When the term ends, the marriage automatically dissolves without the need for divorce. Sunni Islam does not recognize this institution, making it a distinctly Shia and particularly Iranian practice.
Sigheh serves various purposes. Some couples use it to legitimize a sexual relationship they want to have without committing to permanent marriage. Some families use it to allow a young man and woman to interact more freely, such as during an engagement period. And some men use it essentially as a religiously sanctioned route to sexual relationships with multiple women. Research has found that temporary marriage is driven in many cases by a desire for sexual pleasure and can create conditions that accommodate child marriage, with documented social and psychological harms, particularly for girls and women. Women who enter sigheh arrangements often face social stigma, reduced marriage prospects, and economic vulnerability afterward.3TAJDID. Pathological Analysis of Mut’ah or Temporary Marriage in Iran
Because temporary marriage is not systematically regulated or registered, reliable data on how common it is remain scarce. It is practiced more openly in traditional and religious segments of society and in certain cities, particularly pilgrimage cities like Mashhad and Qom. Many younger, urban Iranians view it with disdain, seeing it as a religious fiction that primarily benefits men.
Premarital Sex and Youth Attitudes
Despite the legal framework, premarital sex is common among Iranian young people. A population-based study in Shiraz found that roughly half of single participants reported having had premarital sex, with a median age of first sexual contact of 18 years. Among those who were sexually active, about half reported having had multiple partners.4PubMed. Attitudes Toward and Experience of Singles with Premarital Sex: A Population-Based Study in Shiraz, Southern Iran These are striking numbers given that all of this activity is technically illegal.
Research conducted in Tehran has found paradoxical attitudes among residents: people simultaneously hold conservative stated beliefs about sexual morality and engage in or accept behavior that contradicts those beliefs. Researchers have described this as reflecting an ongoing socio-cultural transition in sexual attitudes across different age groups.5PubMed Central. Paradoxical attitudes toward premarital dating and sexual encounters in Tehran, Iran: a cross-sectional study In other words, what people say in public and what they do in private are often very different things, and younger generations are increasingly unwilling to maintain that gap.
This disconnect is amplified by digital technology. Social media and messaging apps have created private spaces where young Iranians can meet potential partners, flirt, and arrange dates far from the scrutiny of family or authorities. Research on Facebook use in Muslim-majority countries has documented how online platforms function as alternative spaces for romantic connection in socially conservative societies where public courtship is restricted.6Media, Culture & Society. Digital romance: the sources of online love in the Muslim world In Iran, where many global platforms are blocked but widely accessed through VPNs, this dynamic is especially pronounced. Apps like Telegram and Instagram have become de facto dating platforms.
White Marriages and the Rise of Cohabitation
One of the most visible signs of changing sexual norms is the emergence of so-called “white marriages” — a term Iranians use for couples who live together without any form of marriage contract. The concept has caused alarm among religious authorities and state institutions precisely because it falls entirely outside the legal framework. Under Shia law, any intimate relationship between an unmarried couple is considered illegal, making cohabitation not just socially taboo but technically criminal.7Anthropology of the Middle East. The Legal Debate on the Phenomenon of ‘White Marriages’ in Contemporary Iran
White marriages are most common among educated, urban young people who reject both permanent and temporary marriage for various reasons: economic inability to afford a wedding, ideological opposition to the institution of marriage, desire for personal freedom, or simply a preference for testing compatibility before committing. The phenomenon has sparked public debate involving clerics, lawmakers, and academics, all struggling with how to respond to a practice that is both growing and essentially invisible to official statistics. No one registers a white marriage, so no one knows exactly how many couples are living this way. What is clear is that the practice has moved from being unspoken to being openly discussed in Iranian media and scholarship.
Virginity, Honor, and Hymenoplasty
For Iranian women who have had premarital sex, the social consequences can be severe. Virginity at marriage remains a powerful expectation in much of Iranian society, and a woman’s failure to present herself as virginal can lead to family shame, broken engagements, domestic violence, or worse.8PubMed. Recreating Virginity in Iran: Hymenoplasty as a Form of Resistance This pressure has fueled demand for hymenoplasty, a surgical procedure to reconstruct the hymen.
Hymenoplasty occupies a complicated position in Iranian society. In late 2018, Ayatollah Makarem Shirazi issued a fatwa approving the procedure for women who had lost their virginity before marriage, arguing that the surgery could restore a woman’s virginity and therefore her honor. The ruling was highly controversial because it implicitly acknowledged the reality of premarital sex while simultaneously reinforcing the idea that a woman’s value is tied to physical virginity.9PubMed. “Sewed girl” pronounced “virgin”: hymenoplasty and the shift in rhetoric of virginity in Iran Critics have pointed out the deep contradiction: a religious establishment that punishes sex outside marriage also provides a surgical escape hatch that allows women to conceal it, preserving the appearance of the very moral order that has already been breached. Anthropological research has framed the choice to undergo hymenoplasty as a form of resistance by women navigating an impossible set of expectations, rather than simply a capitulation to patriarchal norms.
Family Planning and the Pronatalist Reversal
Iran’s history with reproductive policy is a story of dramatic reversals. After the 1979 revolution, the new government dismantled the existing family planning program and introduced pronatalist policies that encouraged large families.10PubMed. The politics of population policy in the Islamic Republic of Iran Then, in the late 1980s, facing economic strain and a baby boom, the government reversed course and launched one of the most successful family planning programs in the developing world. The total fertility rate plummeted from about 6.5 children per woman in 1960 to roughly 1.6 by 2012, well below the government’s own target.11PubMed Central. Iran’s shift in family planning policies: concerns and challenges Contraceptives were widely available, premarital counseling included family planning education, and the program earned international praise.
Then came a second reversal. Alarmed by the low birth rate, Iranian leaders began promoting pronatalist policies again in the 2010s, culminating in the 2021 Family Protection and Young Population Law. This legislation restricted access to contraception, limited prenatal screening, and made obtaining a legal abortion even more difficult. The consequences have been measurable. In one comparative study in Ardabil, modern contraception use dropped from about 67% of women before the policy change to 31% after, unwanted pregnancies jumped from roughly 29% to 49%, and the rate of women reporting at least one abortion rose from about 14% to 22%.12PubMed Central. The impact of new population policies on women’s reproductive health pattern in Ardabil, Iran: a comparative cross-sectional study
A qualitative study on unsafe abortion found that restricting prenatal screenings and family planning access has pushed many women toward unsafe terminations, violating what researchers describe as the ethical principle of preventing harm.13PubMed Central. Reasons for unsafe abortion in Iran after pronatalist policy changes: a qualitative study A systematic review of abortion trends from 2005 to 2022 reached a similar conclusion, warning that the new population policies and stricter abortion law could lead to increases in both the number and the danger of abortions.14PubMed Central. The abortion trend after the pronatalist turn of population policies in Iran: a systematic review from 2005 to 2022 The irony is that a policy designed to produce more children may be producing more dangerous pregnancies instead.
Sex Education and What Young Iranians Actually Learn
Formal sex education in Iranian schools is minimal and widely criticized by the students who receive it. A qualitative study of female adolescents found deep dissatisfaction. Students reported that sexual health topics were not treated as a priority, educators avoided or evaded the subject, the content that did exist was designed to frighten rather than inform, and what was taught did not match what adolescents actually needed to know.15PubMed Central. Female adolescents’ experiences and perceptions regarding sexual health education in Iranian schools: A qualitative content analysis
The barriers are not just pedagogical. A study surveying healthcare providers found that about half of school principals and staff actively opposed sexual health education for adolescents, and over half of providers identified conflict between sexual education and societal cultural beliefs as a major obstacle. The most commonly cited organizational barrier was the lack of media and educational facilities for teaching sexual health.16Journal of Midwifery and Reproductive Health. Barriers to Sexual Health Education for Female Adolescents in Schools from Health Care Providers’ perspective The result is that most young Iranians get their sexual information from peers, the internet, and pornography rather than from any structured educational source. This gap between what young people need to know and what they are told helps explain the high rates of unprotected sex, STI risk, and unwanted pregnancy that researchers consistently document.
HIV, STIs, and Harm Reduction
Iran stands out in the Middle East and North Africa region for its relatively progressive approach to HIV prevention and harm reduction, particularly for people who inject drugs. The country has implemented needle exchange programs, methadone clinics, and even in-prison harm reduction services that are unusual in the region. Drug injection remains the primary driver of HIV transmission in the country.17PubMed Central. HIV in Iran: onset, responses, and future directions
Among female sex workers, who represent a key population for understanding sexual transmission, HIV prevalence dropped from about 4% in 2010 to roughly 2% in 2015, a decline researchers linked to reduced drug injection in that population. However, other sexually transmitted infections remained common: about 6% tested positive for chlamydia, 12% for trichomoniasis, and 42% for human papillomavirus.18PubMed. Declining trends in HIV and other sexually transmitted infections among female sex workers in Iran could be attributable to reduced drug injection: a cross-sectional study These numbers are a reminder that HIV is only one piece of the sexual health picture, and that populations involved in sex work face substantial health risks that go far beyond a single virus.
Sex Work and Its Drivers
Sex work is illegal in Iran, but it exists. Qualitative research with women involved in sex work in Tehran identified five broad categories of factors that push women into the trade: family instability (including family breakdown and spousal infidelity), social pressures (including addiction and poverty), materialistic aspirations, social insecurity (including experiences of sexual violence), and personality factors like low self-esteem or lack of job skills.19PubMed Central. Exploring the reasons for women to engage in sex work in Tehran, Iran: A qualitative study The picture that emerges is not one of free choice or moral failing but of women navigating compounding vulnerabilities in a society that offers few safety nets for those who fall outside the norms of family support and formal employment.
Same-Sex Lives and Queer Iranians in Exile
For gay, lesbian, bisexual, and queer Iranians, the legal environment creates pressures that extend far beyond the criminal code. Research comparing gay Iranian men with US samples found that Iranian men reported higher levels of discrimination and heterosexist harassment.20PubMed Central. The Relationship Between Discrimination, Heterosexist Harassment, Rejection, and Substance Use in Iranian Gay Men The study linked this discrimination to substance use, suggesting that the hostile environment has tangible health consequences beyond the direct threat of legal punishment.
Many queer Iranians leave the country. A large research project based at the University of Sussex conducted interviews with 57 queer Iranians living in exile in Turkey, the UK, and Canada, as well as a smaller number still in Iran. The study found that identity formation for queer Iranians in exile is a complex process shaped not only by the asylum system, which often requires people to present their sexuality in specific ways to gain protection, but also by the broader experience of displacement and cultural renegotiation.21PubMed Central. Putting People in Boxes: Iranian Exiles and Queer Identities Participants had diverse backgrounds in terms of sexual orientation, gender identity, religious belief, and socioeconomic status, challenging any single narrative about what it means to be queer and Iranian.
Transgender Recognition and the Khomeini Fatwa
One of the most frequently cited paradoxes of sexuality in Iran is that while homosexuality is criminalized, gender reassignment surgery is legally permitted and even partially state-funded. This policy traces back to a fatwa by Ayatollah Khomeini that used the theological principle of original permissibility and the concept of personal authority over one’s body to allow sex reassignment surgery for individuals diagnosed with gender dysphoria. The fatwa has shaped Iranian state policy, resulting in formal medical protocols and insurance coverage for the procedure.22Hikmatuna : Journal for Integrative Islamic Studies. Maqāṣid al-Syarī’ah in Islamic Jurisprudence and Transgender Rights: A Comparative Analysis of Fatwas in Egypt and Iran
This does not mean life is easy for transgender Iranians. Access to surgery involves navigating a bureaucratic medical system, and social acceptance varies enormously. There are also credible reports that some gay and lesbian Iranians have been pressured to undergo gender reassignment as a way to “resolve” their homosexuality within a framework the state can accept. The legal recognition of gender transition and the criminalization of same-sex desire create a strange landscape where changing your body to fit a heterosexual norm is sanctioned, but loving someone of the same sex is not.
Reproductive Medicine and Donor Gametes in Shia Islam
Shia jurisprudence has also opened doors in reproductive medicine that remain closed in most Sunni-majority countries. While Sunni religious authorities generally prohibit third-party gamete donation (egg or sperm from someone other than the married couple), religious rulings from Iran have created pathways for infertile couples to use donor gametes. This has had ripple effects across the Shia world, particularly in Lebanon, and has led to reproductive tourism by Sunni couples crossing borders to access treatments permitted under Shia rulings but forbidden under Sunni ones.23PubMed. Islam, Assisted Reproduction, and the Bioethical Aftermath Iran now has a substantial fertility clinic industry, and the availability of assisted reproduction, including surrogacy, is far more developed than in most neighboring countries.
Sexual Violence and the Iranian #MeToo Movement
Sexual harassment and assault are widespread but underreported problems. An Iranian magazine investigation found that 90% of the women interviewed at a sample of media outlets had experienced sexual harassment at least once while working.24ScienceDirect (Elsevier) / Women’s Studies International Forum. Standing on top of society’s sexist load: Gate-keeping activism and feminist respectability politics in the case of the Iranian MeToo Movement A #MeToo-style movement did emerge in Iran, largely through social media, and it achieved concrete results including the prosecution and conviction of serial rapist Keyvan Emamverdi by an Iranian court in 2022 for the drugging and rape of at least nine women.
The legal framework, however, creates unique obstacles for victims. Because the law classifies rape as a subcategory of sex outside marriage, a woman who reports a rape risks being investigated for zina herself if her account is not believed or if the burden of proof is not met. The evidentiary standards for proving rape under Islamic law are extremely high, requiring either a confession or testimony from multiple witnesses. This structural trap deters reporting and means that the vast majority of sexual violence goes unaddressed by the legal system. The #MeToo movement in Iran has also faced internal debates about respectability politics and gatekeeping, with some activists criticized for policing which victims are “worthy” of public support.
Sexual Dysfunction and Medical Help-Seeking
Even within the context of legal, married sex, Iranian men and women face barriers to sexual well-being. A study of newly married men in Sari found that about a quarter experienced some form of sexual dysfunction, with difficulties related to sexual arousal being the most common. Only about a third of men with dysfunction sought any professional help, and among those who did, fewer than half visited a specialist.25PubMed Central. Sexual Dysfunction and Help Seeking Behaviors in Newly Married Men in Sari City: a Descriptive The reluctance to seek help reflects a broader cultural reticence about discussing sexual problems, compounded by the fact that many couples enter marriage with little practical knowledge about sex. Premarital counseling sessions, which are mandatory for marriage registration in Iran, are supposed to cover sexual health but are widely criticized for being perfunctory, moralistic, and focused more on religious obligations than on practical information.
