A container assembly comprises a vessel for containing a biological medium, gametes and/or one or more embryo(s). The vessel has a COpermeable seal and a closure valve device for selective access. A buffer chamber for a COenriched atmosphere cooperates with the vessel and is in communication with the COpermeable wall. Such a container assembly is particularly adapted for intravaginal use in which case the permeable seal prevents ingress of vaginal secretions. The buffer chamber mediates the aqueous pH in the vessel after the container assembly is removed from a COenriched environment.

Incubation and/or storage container system and method

A fertilization and culture container, e.g. for intravaginal use, comprises a container body having an orifice for introducing a culture medium, one or more oocytes and sperm, resealable closure means for selectively opening and closing the container body orifice, the container body having a main chamber for receiving the culture medium, oocytes and sperm and a microchamber for collecting for retrieval of one or more embryos. The container body has elements for restricting access of retrieval catheter or pipette relative to the microchamber. At least a portion of a sidewall of the container body defining said microchamber is transparent and of optical quality for microscopic inspection of embryos prior to and/or during retrieval with a catheter or a pipette.
