Reproduction and genetics guidance
Genetics guidance is the exchange through which an expert in genetics provides patients and their families with information and support on a genetic condition, inheriting that condition, the risk of recurrence and the implications for the individual and his […]
Physiological conditions in embryo culture: reduction of the amount of oxygen in the incubator

These are just some of the questions that couples might ask at an important time during their treatment, just before embryo transfer. In all cases of fertility treatment involving the in vitro fertilisation (IVF) laboratory, it is essential that all couples […]
A comparison of the phases in IVF and ICSI treatment
