Dr. El Azzi’s research interests include ovarian follicle development, corpus luteum formation, luteolysis, embryo development, and pregnancy maintenance. Specializing in reproductive physiology and follicle dynamics regulation associated with follicle selection and dominance in a postdoctoral research training at Dr. Milo Wiltbank’s lab. Ph.D. in dairy cattle reproduction (2022) at The University of Lavras, Brazil. The Ph.D. dissertation focused on pregnancy maintenance using ovulatory inducers to accessory and original CL formation in recipient dairy heifers and cows receiving IVP and IVD embryos. The research was developed at the University of Wisconsin-Madison, Department of Medical Sciences. Master in equine reproduction (2018) with the induction of ovulation using different doses of GnRH and PGF in mares. Doctor of Veterinary Medicine (2016) at The University of Lavras, Brazil.
