Egg deposition of maternal testosterone is primarily controlled by the preovulatory peak of luteinizing hormone in Japanese quail

Highlights • Pre-ovulatory LH surge can control variability in yolk T levels. • High yolk T deposition was not reflected in permanently increased plasma T levels. • Plasma LH response to GnRH did not explain differences in pre-ovulatory LH surge.
