Micromanipulation and ICSI

Micromanipulation of eggs and sperm requires specialized media, solutions, equipment and training. Irvine Scientific offers high quality media designed to facilitate the in vitro preparation of gametes prior to micromanipulation procedures, such as Intra-Cytoplasmic Sperm Injection (ICSI), assisted hatching, and embryo biopsy.

ICSI has grown to be the most common ART procedure in many parts of the world due to its higher rate of fertilization and ability to fertilize with low quality sperm samples. Hyaluronidase and polyvinylpyrrolidone (PVP) are the two essential ICSI solutions. Hyaluronidase prepares the oocytes by removing the cumulus surrounding it, and PVP slows or immobilizes sperm to facilitate selection of motile sperm for injection. Multipurpose Handling Media provides a safe environment for fertilization before transfer into embryo culture medium.

Embryo biopsy is a rapidly growing technique due to increased demand for preimplantation genetic diagnosis (PGD). A portion of the embryo or blastocyst is biopsied and tested for genetic disorders prior to embryo transfer. The results aid selection of genetically normal embryos and, in some cases, may also help pregnancy rates. Embryo Biopsy Medium is a culture medium for 4-10 cell embryos during biopsy for PGD.

Assisted hatching facilitates the embryo's hatching process from the zona pellucida. The zona is drilled using a PZD needle, laser pulsing, or Acidified Tyrode's Solution.  Tyrode's Solution - Acidified is a micromanipulation media with very acidic pH that can break down the zona pellucida.


Irvine Scientific distributes Sunlight Medical micropipettes in the United States and many other regions worldwide. Sunlight Medical Inc (SLM) manufactures and supply a complete line of micropipettes for in vitro fertilization (IVF) procedures such as intracytoplasmic sperm injection (ICSI), embryo biopsy, assisted hatching and other related procedures. They also manufacture microtools for research applications and for micromanipulation of non-human gametes and embryos.

SLM micropipettes are designed and manufactured under the direct supervision of embryologists with more than 20 years of experience in assisted reproduction technology (ART) and micromanipulation. Each micropipette is hand-crafted by highly trained technicians in a controlled environment and is individually examined for quality assurance.
