Luxembourgish law prohibits discrimination (both direct and indirect) based on sexual orientation and "change of sex" (within the definition of sex) in employment, education, social security, healthcare, and the provision of goods and services. In addition, hate crime legislation also refers to these characteristics and they are recognised as aggravating factors. Article 1 of the anti-discrimination law, commonly referred to as the "Law of 28 november 2006 on equal treatment" (; ; ), reads as follows: Luxembourgish nationals are allowed to serve in the Armed Forces regardless of sexual orientation. As part of its LGBT Action Plan 2018–2023, Luxembourg has pledged to ensure inclusive educational opportunities for LGBT students, combat violence, harassment and discrimination, guarantee equal treatment in access to health care services and employment, and assure the equality of transgender and intersex individuals. In the past, Luxembourg legally required transgender people to undergo surgery, sterilization and divorce before a change of gender on identification documents. However, on 12 May 2017, the Council of Government approved a bill to regulate the procedure of legal sex changes. An adult person would need to submit an application to the Ministry of Justice to change their legal sex. No surgery, sterilization, divorce or other medical treatment would be required. Minors would be able to apply for a sex change with the consent of their legal guardians. On 31 May, the bill was submitted to the Parliament, and was approved in a 57–3 vote on 25 July 2018. On 27 July 2018, the Council of State gave its consent to skip the second vote. It was promulgated by the Grand Duke on 10 August and published in the official journal on 12 September. The law took effect on 16 September 2018. In Luxembourg, men who have sex with men (MSM) are not allowed to donate blood. In February 2016, Health Minister Lydia Mutsch was investigating the possibility of repealing the blanket ban. Luxembourg's main LGBT rights group is Pink Luxembourg ().
