embryologists
Early development scientists
Embryologists are scientists who study embryos—organisms in the earliest stages of development before birth or hatching.
The field spans both research and clinical practice: some embryologists investigate how cells differentiate and organs form, while others work in fertility clinics handling eggs, sperm, and embryos for procedures like IVF.
The embryologist examined the fertilized eggs under the microscope.
