Annually, about 140 million pregnancies would occur out of which about 25% would be terminated before the fetus reaches viability due to spontaneous or induced abortion (1). Induced abortion would be performed due to various reasons such as having unwanted pregnancy, mother’s or father’s unwillingness to have a child, diagnosing a fetal anomaly or disorder or a maternal disease (2, 3) and it is known as therapeutic abortion when there is a medical need for terminating the pregnancy (before 20th weeks) to save the mother’s life, prevent any mental or physical harm to the mother, or in cases where the fetus is diagnosed with a disorder or disease that would make it nonviable, or to reduce the number of fetuses in multifetal pregnancies (2)..
Although the exact data about abortion in Iran is not available due to the inherent difficulty in reaching all diverse populations of Iran and the sensitivity of the issue, some researchers have tried to estimate the rate of various types of abortion in Iran. Erfani (2016), showed that between 2009 and 2014, the proportion of having lifetime abortion in married women, the general abortion rate, the total abortion rate and the annual number of abortions in married women aged 15–49 who completed the 2009 Tehran Survey of Fertility decreased, respectively, from 8.3–5.6%, from 6.6 to 5.4 abortions per 1,000 women, from 0.18 to 0.17 abortions per married woman and from 10,656 to 8,734. However, the proportion of terminations obtained for nonmedical reasons rose from 68–81% (4) In a 2012 meta-analysis by Motaghi et al., abortion was estimated at 8.9 per 1000 women aged 15 to 44 years and 5.34 per 100 live births (5). According to a study by Rastegar et al. (2014) in Iran in 2012, abortion rates with and without medical reasons were estimated to be 70.5 and 116.9 per 1000 pregnancies, respectively (6).. In a 2015 study by Hosseini et al., women aged 15 to 49 years reported a 3.8% rate of induced abortion (7). Ghofrani et al. (2018) estimated the prevalence of induced miscarriage by both randomized response technique and unmatched count technique 14% and 12%, respectively (8).
In countries where induced abortion is illegal and there are very restrictive rules about abortion, women would seek unsafe abortion (9–12) which is one of the main causes of morbidity and death among the women around the world and is the reason behind the death of 8–18% of pregnant mothers and one eighth of the occurred complications in pregnancy (13) as well as psychological, socio political and judicial consequences (14). According to a study by Majlesi et al. (2008), 12% of 417 referrals for abortion in a hospital in Isfahan declared illegal abortion (15). So, we can come to the conclusion that one of the ways to prevent unsafe abortion is to enact the required laws that would allow women to have access to healthy abortion in the necessary cases (16, 17). Induced abortion, at all ages, before or after viability (18), and in the entire world, has always encountered ethical, philosophical, biological, religious and legal challenges (16, 19). Currently, the laws related to abortion are different in various countries and cover a range from full ban to full freedom (20, 21).
In Iran, for the first time in 1997 the permission for abortion was issued only for fetal major thalassemia and anencephaly cases before ensoulment which was estimated to be around 19 weeks of pregnancy. In 2002, the national committee of abortion approved a regulation with limited number of definitive maternal and fetal indications suggested for therapeutic abortion. According to the Single Article Act of therapeutic abortion [June 2005], wide range conditions for receiving permission for abortion and relating processes have been defined. According to this Act, therapeutic abortion is legally authorized with the consent of the pregnant mother after definite diagnosis of fetal anomaly or a life threatening maternal disease, by three medical specialists and its confirmation by the legal medicine organization before 19 weeks of pregnancy (22, 23).
According to the study by Tofiqhi et al. (1999), abortion permission was issued for 51.4% of the 245 cases (24). Following the evolution of regulations in 2002, Sadr et al. (2006) surveyed all abortion applicants referring to legal medicine centers in the country in 2004 reporting that out of 1101 permission issued, 35.8% were for maternal and 63.9% for fetal cases. Since the last amendment to the law in 2005, dispersed provincial studies have been conducted. Sharifi et al. (2019) surveyed all 428 abortion applicants in Kermanshah between 2005 and 2010, reporting 82.7% of permits, including 81% fetal and 19% maternal (25). According to a 6 years study of 1664 cases of abortion applicants in Fars Province, 79.6% were fetal and 20.4% maternal (26, 27). According to the study by Vasegh et al. (2018), for 48% of the 1378 female applicants for abortion referred to the legal medicine department of Tehran province, permissions were issued during a one year period 2011-12, of which 90.2% were fetal and the rest were maternal (28). In the Isfahan province study, over a 4 year period from 2011 to 2014, 629 of 830 (75.8%) referred women for fetal causes has been received the abortion permission (29). In Hormozgan province, abortion was permitted in 77.9% of the 281 clients in a one year period of 2016-17 (30). Studies show that the number of abortion applicants and the percentage of licensing has increased over the years.
Currently, if in the primary screenings and investigations by the prenatal caregivers (gynecologists and midwives) any fetal or maternal problem would be detected, the pregnant mother would be referred to the selected special center of legal medicine in the province and after receiving the permission, she would be referred to the hospital with the permission to have the safe abortion under the supervision of healthcare providers. So, it is more than two decades that therapeutic abortion is being performed in Iran safely and legally and it has created a ground for decreasing the number of unsafe abortions and their complications and also decreasing the burden of diseases that continuing pregnancy would cause.
Considering that no comprehensive country level study has been conducted after 2006, the present study has been conducted to evaluate the number of requests for legal abortion through the country and the frequency of issued permissions and the frequency of fetal and maternal causes.
