Leibniz's letter covered several topics. He discussed the different position about spermatozoids held by the Italian physician Antonio Vallisnieri, who thought that the animal was already in the egg. Leibniz, as he had written in his recent book Essais de Théodicée, shared Leeuwenhoek's opposing view.

Leibniz hoped that Leeuwenhoek would continue with the publication of his Send-Brieven.

He urged Leeuwenhoek to establish a school for young people to learn how to research with the microscope.

Finally, he asked Leeuwenhoek's opinion about a book by Nicolaas Hartsoeker, Conjectures Physiques.
