Later, the more technically demanding sex reassignment surgery female-to-male was also offered at Kandang Kerbau Hospital and at Alexandra Hospital, performed by gynaecologists such as Dr. Ilancheran. A Gender Identity Clinic (GIC) and Gender Reassignment Surgery Clinic were set up at the National University Hospital two decades later. It was headed by Prof. S Shan Ratnam until his retirement in 1995, after which leadership passed to his nephew, Dr. Anandakumar. In fact, for 30 years, Singapore was one of the world leaders in SRS, performing more than 500 such operations. This gave a new lease on life to the many transgender individuals whose bodies did not match their gender identity. As one consequence of this, Bugis Street and Johore Road started to become populated with a range of transgender people from transvestites to iatrogenic intersex individuals to fully transformed women. In the 1970s, a well-known transsexual model was occasionally featured in Her World magazine. Since the mid-1970s, post-operative transsexual people had been discreetly lobbying to be given the right to marry opposite-sex spouses. In 1996, a bill was presented before the Parliament of Singapore and the Women's Charter amended to read:  The minister moving the bill argued that since 1973, the government's intention was for people who had changed gender/sex to live a life according to their new gender, including the right to marry. Through an oversight, the law relating to marriage had not been re-aligned with the official policy to recognise sex reassignment surgery. Now that the courts had illuminated this inconsistency after a landmark case in which a woman sought and won the annulment of her marriage to a trans man (Lim Ying v Hiok Kian Ming Eric), it was necessary to amend the Women's Charter to ensure that the original intent was not undermined. Transgender people were officially granted their wish on 24 January 1996 via an announcement by MP Abdullah Tarmugi without much public fanfare or opposition. The Gender Identity Clinic (GIC) at the National University Hospital quietly closed in 2001. The official explanation was that the gynaecologist in charge had left for private practice, and without him, the clinic did not have the skills to perform SRS. However, as early as 1987, the Ministry of Health had been directing hospitals to stop doing such operations on foreigners. It also discouraged them for Singaporeans, saying 'the increased danger of AIDS with such patients poses unnecessary risk to hospital staff'.
