Reproduction Center

Reproduction Center

We are introducing state-of-the-art technology and have installed a reproduction center dealing with advanced reproductive medicine. In April of 2007, we extended the In Vitro Fertilization Lab to two rooms, and ensured that the capacity can support up to 20 OPU per day.

Reproduction Center Equipment



Fertilized oocytes, immature oocytes, etc. are cultivated here. The gas concentration, humidity, and temperature are always kept constant so that they are close to the environment inside the uterus.


It is used for work performed at a relatively low magnification such as oocyte inspection, freezing, and thawing.

Cryopreservation Container


A container for cryopreserving embryos, oocytes, and sperm entrusted to us by patients. When stored in liquid nitrogen, the temperature inside reaches close to -200 ℃.

Clean Bench


Equipment for aseptic operation, including a stereomicroscope and an inverted microscope. Oocytes, sperm, and culture medium are all handled in this.

Inverted Microscope


It is a type of microscope that observes an object from below, and is characterized by its high magnification. Most of the operations such as observation, microinsemination (ICSI), and AHA are performed using this microscope.



Used for washing sperm.
