• oocyte
  • The oocyte is pierced through the oolemma and the sperm is directed into the inner part of the oocyte (cytoplasm). (wikipedia.org)
  • The sperm is then released into the oocyte. (wikipedia.org)
  • Comet assay), both naturally and in the laboratory, and the procedures by which these sperm are injected directly into an oocyte. (springer.com)
  • The results of this study emphasize the importance of selecting good quality sperm for oocyte injection, especially in cases involving very severe oligozoospermia. (biomedsearch.com)
  • citation needed] The Institute's American activities involve a large donor egg program, one of the world's major group of sperm banks and egg banks, one of America's most active preimplantation genetics testing centers, and oocyte cryopreservation via vitrification in addition to more conventional IVF, infertility, and genetic services. (wikipedia.org)
  • Schatten's work on fertilization examines the differential inheritance of cellular components contributed by the sperm and egg, respectively, as well as the program of oocyte activation and cell division during meiosis and mitosis. (wikipedia.org)
  • Procedures performed on sex cells before fertilization may instead be referred to as methods of oocyte selection or sperm selection, although the methods and aims partly overlap with PGD. (wikipedia.org)
  • Semen
  • Based on semen analysis, the volume was determined to be 3.4 cc, with a concentration of 2 × 10 6 /mL, 73% immotility, and 99% sperm with head and neck anomalies. (hindawi.com)
  • The presence of round headed sperm in a semen analysis sample confirms the diagnosis of globozoospermia. (wikipedia.org)
  • testes
  • It can be used to help men who have a total blockage of any part of the male tubing from the testes as sperm can be 'sucked' directly from the blocked tubing or from the testicle itself. (essentialparent.com)
  • testis
  • Prior to FNA Mapping, testis biopsy was the major procedure for determining the quality of sperm presence. (wikipedia.org)
  • Testis biopsy is a more invasive procedure than FNA Mapping, and studies have shown that FNA Mapping provides better and more complete information about sperm presence. (wikipedia.org)
  • Spermatozoa
  • Lirias: Application of the Fertilase-laser system versus the conventional mechanical method to immobilize spermatozoa for intracytoplasmic sperm injection. (kuleuven.be)
  • This means that the spermatozoa show the same abnormality, and over 85% of spermatozoa in sperm have this abnormality. (wikipedia.org)
  • Studies suggest that globozoospermia can be either total (100% round-headed spermatozoa without acrosomes) or partial (20-60% round acrosomeless spermatozoa with normal sperm also identified in the sperm count,) however it is unclear whether these two forms are variations on the same syndrome, or actually different syndromes. (wikipedia.org)
  • morphology
  • Even with severe teratozoospermia, microscopy can still detect the few sperm cells that have a "normal" morphology, allowing for optimal success rate. (wikipedia.org)
  • retrieval
  • There are no risks to the male partner once the sperm has been obtained - and only negligible risks if sperm retrieval techniques are used. (scrcivf.com)
  • This technique has been important because it has improved identification of men who are likely to have a successful sperm retrieval while at the same time avoiding costly and unnecessary assisted reproductive techniques. (wikipedia.org)
  • FNA Mapping failed to diagnose the degree of "patchiness" of sperm production in azoospermic men and determine, among other things, whether a sperm retrieval would succeed in a specific patient. (wikipedia.org)
  • Technique
  • This technique may be suggested if fewer than 100,000 sperm may be capable of being retrieved for routine IVF, or in cases where very few sperm shows adequate movement. (essentialparent.com)
  • developed MicroSort, an important flow-cytometric human sperm separation technique for preconceptual gender selection, which has already produced over 1,000 births. (wikipedia.org)
  • eggs
  • Your spouse may produce a sperm sample himself by ejaculating into a cup on the same day as your eggs are collected. (healthsparks.org)
  • count
  • If your spouse has a low sperm count as a result of a genetic problem, this could be passed on to any sons you have together. (healthsparks.org)
