Embryologists study the development of embryos. Their duties and responsibilities include collecting eggs from patients at the right time of the cycle, inseminating them and checking whether they have been fertilised.

They assess the quality of the embryo by grading it and monitoring its development. The embryo is then transferred back into the patient. Specialised techniques are used to identify the eggs and to perform the entire procedure.

Other areas of specialisation that embryologists could work in include semenology (analysing and preparing semen or sperm for therapeutic use and auditing and maintaining sperm banks; cryopreservation (the use of liquid nitrogen to freeze and preserve eggs, embryos, semen, as well as testicular and ovarian tissue).

Embryologists are responsible for ensuring that all equipment is well maintained to operate efficiently, including monitoring laboratory stock levels and ordering consumable items. They also check that all consent forms from patients are properly completed and checked before they carry out any procedures, and keep precise records of the procedures. They work with a highly skilled team of other medical professionals from various medical fields.

Embryologists work in a clean, hygienic working environment, predominantly in laboratories and operating theatres.
