“…Due to the different absorption behaviour of its 2.1 mm emission in water the holmium:yttrium-scandian-gallium-garnet laser (Ho:YSGG) runs without need for additional micromanipulating (Neev et al, 1995;Schiewe et al, 1995a); however, embryos had to be moved to quartz slides causing superfluous physiological stress, a fact limiting its applicability.…”

Recently, one laser system has been introduced in IVF fulfilling all safety requirements, while achieving a high standard of reproducibility in terms of ablation diameter. This 1.48 microm wavelength indium-gallium-arsenic-phosphorus (InGaAsP) semiconductor laser offers a variety of laser applications to the embryologist. On the one hand, zona pellucida of oocytes or embryos can be manipulated in order to facilitate ICSI or biopsy and assist hatching, and on the other, spermatozoa may be paralysed or immobilized prior to usage. To conclude, the 1.48 microm diode laser provides a promising tool for the microdissection of subcellular targets. The diode laser stands out due to the rapidity, the simplicity and the safety of the procedure which is supported by healthy offspring after laser application.

“…It was the simultaneous development of non-contact IR laser systems in the mid-1990's in Europe (1084 nm: [84,85]) and the USA (2100 nm: [86,87]) that allowed the technology to progress safely into the assisted reproductive technologies field. The holmium:yttrium scandium gallium garnet (Ho:YSGG) laser system devised by Dr. Yossi Neev was effective (Figure 2) but involved a large box device requiring extensive mirror calibrations.…”

The concept of assisted reproductive technologies was most notably derived from the late 19th Century experiments of Sir Walter Heape who successfully transplanted rabbit embryos. Interestingly, it was not until the late 1940's and 1950's that renewed interests in rabbit embryo transfer and cryobiology occurred. The history behind developing effective procedures can be fascinating, though few could be more accidental than Dr. Chris Polge's discovery of glycerol (1948), from a mislabeled bottle of sugar solutions, being an effective cryoprotective agent for sperm freezing. The purpose of this review paper is to discuss four key scientific breakthrough technologies occurring between 1985 and 1995, which ultimately shaped the future of today's human in vitro fertilization (IVF) industry. More importantly, this paper highlights the foundation of underlying related discoveries and some unique stories involving their development and publication. In the end, this paper emphasizes the value of understanding scientific discovery timetables and the eventual re-discovery in the hands and minds of creative, determined and dedicated scientists, as history tends to repeat itself before its useful application is realized.

“…For this reason, some investigators used this WL in the contact mode and some used it as a free beam. It is not the intent of this review to discuss technical details, such as pulse duration, energy, or pulse repetition rate; however, it is important to realize that such details will further determine the laser effects [44].…”

“…Our group [44,45] used the Ho:YSGG (2,100 nm) as a free beam delivered through an inverted microscope and quartz glass dish to perform LAH in two-cell mouse embryos. Control embryos were treated with human tubal fluid (HTF) culture with or without serum (HTF-s, HTF-o) or with late serum supplementation (HTF-o/s).…”
