Assisted Reproductive Technology (ART) refers to a range of laboratory techniques that combine sperm and egg for fertilization. Since the birth of the first in vitro fertilization (IVF) or ‘test tube’ baby in 1978, the field of IVF has been transformed with several technological discoveries that have led to a remarkable expansion of the treatable conditions as well as an outstanding increase in making possible the dreams of many couples to conceive. The embryology laboratory, where embryos are produced, grown and nourished during an IVF cycle, is one of the key components of a fertility center. While patients don’t necessarily know what happens behind the scenes during an IVF cycle or how their embryos are produced, having a state-of-the-art embryology laboratory is what separates an average from an excellent fertility center.
The clinical part of embryology department of RI-RB gives our patients access to some of the most accomplished and national renowned fertility specialists in the field. A wide range of advanced ART services are also available, including:

  • Intra uterine insemination (IUI)
  • In vitro fertilization (IVF)
  • Intracytoplasmic sperm injection (ICSI)
  • Assisted hatching
  • In vitro maturation (IVM)
  • Blastocyst culturing
  • Embryo cryopreservation
  • Preimplantation genetic diagnosis (PGD)
  • Donor oocyte (egg) services
  • Oocyte cryopreservation (egg freezing) services


After fertilization, embryos are cultured in the embryology laboratory. This is done under very strict conditions in specialized media in an incubator. Embryos are typically transferred back into the uterus at either the cleavage stage (on day 3 after retrieval) or the blastocyst stage (on day 5 after the retrieval).
The clinical part of embryology department of RI-RB offers extensive training in routine and advanced laboratory tests in assisted reproduction techniques (IUI, IVF/ ICSI), gamete cryopreservation and PGD. Through one-on-one training in laboratory procedures, candidates develop technical expertise in all of the essential techniques, including comprehensive semen analysis, sperm preparation procedures, assisted reproduction (IVF/ICSI) techniques and cryopreservation protocols for semen, testicular and oocytes/ embryos. At the completion of the program, candidates receive a Certificate of Training recognizing their achievements.Also, in addition to patient treatment we focus on research about some aspects of preimplantation embryo. These aspects are:
  • IVM
  • IMSI and best approaches to sperm selection
  • Cryopreservation of gamete and embryo
  • Low fertilization
  • Effect of oxidative stress on sperm and oocyte
