spermatogenic การใช้

• In several species of the spermatogenic tissue also increases proportionately.
• Mutations in this gene have been linked to severe spermatogenic failure and infertility in males.
• In between the Sertoli cells are spermatogenic cells, which differentiate through meiosis to sperm cells.
• Inhibin is produced by the spermatogenic cells, which, also through inactivating activin, inhibits the hypothalamus.
• Mutations in this gene are associated with an infertility disorder, spermatogenic failure type 9 ( SPGF9 ).
• Rats with spermatogenic failure at meiosis were found to have a deletion in the exon 8 portion of the FKBP6 gene.
• Males with Klinefelter syndrome may have a mosaic 47, XXY / 46, XY constitutional karyotype and varying degrees of spermatogenic failure.
• It is expected that the accumulation of homocysteine residues and the impaired transmethylation reactions are underlying factors of spermatogenic failure in male infertility.
• In 2012, Page characterized the most common genetic cause of spermatogenic failure, the deletion of the AZFc region of the Y chromosome.
• Over the same period there was a significant increase in the number of men with no mature sperm cells, a condition known as spermatogenic arrest.
• It is known that heterozygous chromosomal rearrangements lead to spermatogenic disturbance or failure; however the molecular mechanisms that cause this are not as well known.
• The incidence of complete spermatogenic arrest rose from 8 percent to 20 percent, and of partial spermatogenic arrest from 31 percent to 48.5 percent.
• The incidence of complete spermatogenic arrest rose from 8 percent to 20 percent, and of partial spermatogenic arrest from 31 percent to 48.5 percent.
• This led to enzymes involved in spermatogenesis, spermatogenic DNA polymerase beta and recombinase activities evolving a unique temperature optimum, slightly less than core body temperature.
• He has studied spermatogenesis and spermatogenic cycles in amphibians and reptiles, and his work on sperm morphology and glandular epithelium includes the first descriptions for many species.
• The basis for the universal recommendation for early surgery is research showing degeneration of spermatogenic tissue and reduced spermatogonia counts after the second year of life in undescended testes.
• In the California Sheephead ( " Semicossyphus pulcher " ), a type of wrasse, when the female changes to male, the ovaries degenerate and spermatogenic crypts appear in the gonads.
• "' Mild androgen insensitivity syndrome "'( "'MAIS "') is a condition that results in a mild impairment of the spermatogenic defect and / or reduced secondary terminal hair.
• Treatment of male mice with melphalan, a bifunctional alkylating agent frequently employed in chemotherapy, induces DNA lesions during meiosis that may persist in an unrepaired state as germ cells progress though DNA repair-competent phases of spermatogenic development.
• Necl-2 : CADM1 ( Cell adhesion molecule 1 ), TSLC1 ( Tumor suppressor in lung cancer 1 ), SynCAM1 ( Synaptic cell adhesion molecule 1 ), IGSF4 ( Immunoglobulin super family member 4 ), sgIGSF ( Spermatogenic immunoglobulin superfamily ), RA175
