Results: From 2002 to 2010 at our institution 4,818 men 18 to 55 years old were diagnosed with cancer, of whom 411 were offered fertility preservation consultation and 249 underwent sperm
cryopreservation. Since program implementation, the annual number of men receiving fertility preservation consultation and undergoing sperm cryopreservation increased by 2.4 and 2.7-fold, respectively, while the total number diagnosed with cancer remained fairly constant. Upon substratifying patients into the more conventional reproductive age range of 18 to 40 years 23.4% of all men with Protein Tyrosine Kinase inhibitor cancer in this group were offered consultation before formalization vs 43.3% after formalization (p<0.05). The overall sperm use and discard rates were 8.4% and 14.8%, respectively.
Conclusions: A formalized institutional fertility preservation program significantly increased the overall number and percent of male patients with cancer who received fertility preservation consultation and pursued sperm cryopreservation. These increases were seen in men with all types of cancer and this website across all demographics assessed at our institution.”
“Mistic represents a family of unique membrane-associating proteins originally found in Bacillus subtilis (M110). As a fusion partner, it has been shown to assist overexpression of foreign integral membrane proteins in E.
coli. We have expressed shorter Mistic homologs from other Bacillus species and surprisingly, unlike M110, found them abundant in the cytoplasm. These Mistic homologs including the corresponding shorter sequence (amino acids 27 through 110 of M110) exist as multimeric assemblies in solution in the absence of detergent. Crystals of Mistic from B. leicheniformis (M2) diffracted to 3.2 angstrom resolution, indicating that it exists as a multimer in the crystalline state as well. Moreover, we show that
although M2 is mostly alpha-helical, it tends to polymerize and form fibrils. Such oligomerization could potentially mask the charged surface of the monomeric Mistic to assist membrane integration.”
“Purpose: We determined Immune system the effects of prostatic brachytherapy on semen parameters and sperm DNA integrity, and the potential impact on fertility.
Materials and Methods: Five screened patients treated with brachytherapy participated in a pilot study visit to undergo early morning blood collection for serum hormone evaluation and semen collection for semen analysis and DNA integrity assay by sperm chromatin structure assay. Data on 7,617 infertile men, each with at least 1 semen analysis and sperm DNA integrity assay, were obtained from an institutional database for comparison. Published data on fertile men were compared to data on those with brachytherapy for DNA fragmentation analysis.
