Scientistshave now successfully used genetically-altered embryonic stem cells to develop artificialsperm, proving how they can easily be employed to fertilize human eggs, andthus produce healthy, usable offspring. The new cells are the first ever tofulfill a set of strict criteria for successful artificial sperm, establishedby three prominent fertility specialists.
Suchachievements are important when the field of infertility treatments is seeingsome very rapid development. With more pharmaceutical companies now developingmedicines and other products to overcome problems regarding infertility, thefield is now focusing its efforts on the development of better tools andtechniques for the same. The development of artificial sperm cells opens upavenues for treatment options which would not have been available before. Italso demonstrates that science is progressing towards the development of bettertools and techniques for the same. This is the gold standard for all scientificbreakthroughs. However, the process by which these cells were developed goesfar beyond the mere achievement of meeting the gold standard.
Variousstudies have determined the effects of different environmental factors onspermatids and the use of different testes in spermatid production. They lookedinto the impact of temperature, pH levels and nutrition on spermatidsproduction as well as the impact on the motility of these spermatids. In thisway, they were able to show how the environmental conditions could affect the developmentof artificialsperm.
