Legal analysis: Egg trading is not clearly defined as a criminal act or suspected of illegal business. Egg collection must be carried out in medical institutions. If a medical institution illegally engages in egg trading, it is suspected of illegal business operation. If the circumstances are particularly serious, he may be sentenced to fixed-term imprisonment of not less than five years and fined. If it is performed by some unlicensed private individuals, or doctors perform assisted reproductive surgery in non-designated institutions, it is suspected of illegal medical practice.
