Most of the reproductive decisions parents make cannot be carried out without the aid of professionals such as physicians, so it might be necessary to regulate professional behavior as well. While some of the infrastructure, such as licensure laws for physicians, is already in place, additional steps may be needed, such as heightened regulation of infertility clinics, where many genetic-engineering interventions will take place.
父母所做的大部分生殖决定都是在医生等专业人士的协助下才能做出的，因此或许有必要同时监管职业操守。一些基础设施，比如医生执业法已经存在，但仍需采取更多的措施，比如加强对妇产科（大量基因工程干预发生在这里）的监管。此外，必须制定评估新技术安全性和有效性的规则，要兼顾这些技术的接受者和他们的后代。
