Must we accept the view of Empedocles of Trinacria that the right ovary (the postmenstrual period, assert others) is responsible for the birth of males or are the too long neglected spermatozoa or nemasperms the differentiating factors or is it, as most embryologists incline to opine, such as Culpepper, Spallanzani, Blumenbach, Lusk, Hertwig, Leopold and Valenti, a mixture of both?
Onartu bear ote degu Empedokles Trinakriakoaren ikuspegia, alegia eskubiko arrautzatokia (ilekoaren ondoko aldia, diote beste batzuek) dala arrak jaiotzearen eragile edo espermatozoide edo nemasperma luzarogi gutxietsiak dirala eragile bereizleak, edo, umegaiei dagozkien gaietan jakitun diran geyenek, esate baterako, Culpepper, Spallanzani, Blumenbach, Lusk, Hertwig, Leopold eta Valentik eusten duten bezala, bien naasketa bat?
