Designed by Embryologists Who Use It
Genea Biomedx’s dedicated embryologists and andrologists have worked passionately in assisted reproductive technology for decades. We understand that high-quality culture media is essential for achieving the best possible outcomes for patients. That is why we have developed, produced, and used our own media formulations since 1991. Gems®, our third-generation culture media suite, has been in clinical use since 2013 and is exported globally.

Gamete Handling & Preparation

Oocyte Retrieval Buffer 50 mL
Conceived to reduce stress on the occytes during their retrieval from ovarian follicles.

Sperm Medium 50 mL
Used to wash and resuspend sperm for the insemination step, in IUI, IVF or in diganostic washing, optimised for usage in a 6% CO2

Sperm Wash Gradient Set
Used to separate sperm from seminal plasma as well as separating highly motile sperm in preparation for insemination.

Sperm Buffer 50 mL
Used to wash and resuspend sperm for the insemination step in intrauterine insemination (IUI), IVF or in diagnostic washing
Growth Media

Fertilisation Medium 50 mL
Used to provide a suitable environment for both oocytes and sperm, to promote optimal fertilisation rates. Supplemented with human serum albumin (5 mg/mL) and gentamicin (0.01 mg/mL)

Cleavage Medium 50 mL
Higher EDTA and concentration of pyruvate, lactate and non-essential amino acids, to support the embryo to reach the cleavage stage

Blastocyst Medium 50 mL
Higher concentration of glucose and essential amino acids, to support the embryo development from cleavage to the blastocyst stage.

Geri® Medium 50 mL
Ready-to-use solution to support extended culture with uninterrupted incubation up to blastocyst stage. Embryos retain their microenvironment for the entirety of in vitro culture.
