Expression of interleukin (IL)-6, IL-8, and CXCR1 is significantly up-regulated in fallopian tubes with tubal gestation, while expression of CXCR2 and IL-6Ra is not changed in comparison with normal fallopian tubes.
Synchronizing ovarian stimulation with follicle wave emergence in patients with a prior suboptimal response resulted in an increase in the number of follicles that developed and serum E2 concentrations; however, corresponding improvements in oocyte, embryo, and pregnancy outcomes were not observed.
In this study analyzing embryo morphology and chromosomal status in relation to rate of embryonic developmental progression, the ability to blastulate, rather than day of blastulation, was found to significantly affect aneuploidy.
Inner cell mass outgrowth is a more sensitive bioassay than blastocyst development and sperm motility for detecting formaldehyde. Evaluation of culture media metabolome has potential as a sensitive QC assay.
We need new and more effective techniques of embryo selection. Oxygen consumption changes depending on the developmental stage, quality, and implantation success. Our observations indicate that oxygen consumption pattern could be a useful new marker of embryo quality.
The improved sensitivity of a fluorescent-based semen analysis technique indicates that a substantial proportion of patients diagnosed as azoospermic by conventional semen analysis may actually have sperm present in their ejaculate.
Adding recombinant follicle-stimulating hormone to human chorionic gonadotropin treatment protocols in adolescent/young adult men with hypogonadotropic hypogonadism results in normal testicular growth and may hasten induction of spermatogenesis.
