Method for preferential production of female turtles, lizards, and crocodiles

摘要

A method for sex reversal in reptiles and their derivatives comprising the steps of sterilizing the surface of a fertilized egg; injecting the egg with a material that causes sex reversal at least before the first two-thirds of incubation of the egg has passed; and sealing any holes in the egg. In a preferred embodiment, the material that causes sex reversal includes natural estrogens or its synthetic mimics. In an alternative embodiment, the material is applied to the surface of the egg. By practicing the aforesaid method, sex reversal in reptiles and their derivatives is accomplished and viable all female sexed hatchlings are capable of being produced thereby.
