“…Several methods for tilapia sex control have been described, including hybridization, chromosome manipulation (polyploidy, gynogenesis, and androgenesis) (Arai and Fujimoto, 2018;Chen et al, 2018), heat temperature (D'Cotta et al, 2001;Khater et al, 2017), and sexual masculinization using hormones (Asad et al, 2010;Popma and Lovshin, 1995). However, most farmers use 17 α-methyltestosterone (MT) hormones, primarily because the process is cheap, efficient, simple, and the hormone is easily excreted after treatment (Asad et al, 2010;D'Cotta, 2018;Bombardelli et al, 2007). Methods of MT administration include immersion and injection, but the most commonly used method is incorporating the hormone into the diet (Baroiller & D'Cotta, 2018).…”

“…The 17α-methyltestosterone (MT) is a synthetic product, a methyl derivative of testosterone (Figure 1), used in medicine to suppress testosterone deficiency and treat symptoms of andropause in men (Bejma et al, 2005). It is a potent agonist of the androgen receptor (Selzsam et al, 2005).…”

“…A adição do hormônio 17-α-metiltestosterona na ração é o método mais utilizado na reversão sexual de tilápias e pode produzir 98% de machos (Mainardes-Pinto et al, 2000) utilizando-se ração suplementada com metiltestosterona (60 mg.kg -1 ) por um período de 30 dias a partir do início da alimentação exógena das larvas. Banhos de imersão de larvas em solução contendo metiltestosterona para masculinização dos peixes, de acordo com outros autores (Bombardelli et al, 2007;Dias-Koberstein et al, 2007), resulta em populações com até 83% de machos.…”
