This is incorrect. In his letters and some of the supplementary writings collected in *The History of Middle-earth*, Tolkien suggests that Orcs, being living creatures similar to Men and Elves, would have needed to reproduce in the same way, which implies the existence of female Orcs.
In one of his letters (Letter 153), Tolkien confirmed that Orcs "bred after the manner of the Children of Ilúvatar," meaning that they would have male and female sexes. However, Tolkien did not delve into the details of Orc society, and female Orcs are not described in *The Lord of the Rings* or *The Silmarillion*. The absence of female Orcs in the narrative might be due to the focus on military campaigns and the traditionally male-dominated armies, or simply because Tolkien chose not to elaborate on this aspect of Orc life.
