Universiti Sains Malaysia's Muslim Students Association held the forum last month, media reported.
The association confirmed that it held the forum in a post on its Facebook page last month, saying it wanted to stop the spread of "LGBT culture" in Malaysia, which went against Islamic principles.
Thilaga Sulathireh, from the transgender rights group Justice for Sisters, said the university forum would incite prejudice and was not an isolated case.
"The messaging was that LGBT people can be changed and LGBT is a form of sickness. That is harmful," Sulathireh said.
"When you tell them LGBT is a form of sickness, it adds to the prejudice that LGBT people face," she said.
The forum organisers did not immediately respond to a request for comment.
Last year, the health ministry planned a contest for teenagers to come up with ideas on how to "prevent" homosexuality and transgenderism, sparking criticism from activists and a change in the plan.
In 2012, authorities issued guidelines and held seminars aimed at helping teachers and parents spot signs of homosexuality in children.
