In vitro fertilization outcomes may be improved by performing frozen instead of fresh embryo transfer. These results could be explained by avoiding the deleterious effects of controlled ovarian hyperstimulation on endometrial receptivity.
No association was demonstrated between follicle-stimulating hormone receptor gene variants and ovarian response in women undergoing in vitro fertilization treatment, but clinically relevant differences cannot be ruled out.
Serum INSL3 correlates with intratesticular testosterone during hCG administration. Measurement of serum INSL3 may be a useful biomarker of intratesticular testosterone during hCG treatment of infertile men.
This study provides the first evidence that inflammasome proteins are present in human 24 semen, and suggests that the inflammatory innate immune response contributes to 25 abnormal semen quality in SCI men.
Examination of total levels and localisation patterns of PLCζ in control and patient sperm. Sperm from control and OAD males exhibited significant variance in total levels and localization patterns of PLCζ protein.
Perfringolysin O selectively permeabilizes the plasma membrane of human spermatozoa and can be used to assess changes in the amount and distribution of the active cholesterol fraction present in this membrane.
Normal semen analysis may not reflect important alterations in protein levels in the seminal plasma. A classic proteomics approach shows that unbalanced apoptosis may prevent normal spermatogenesis in the adolescent varicocele.
Reflections on “Elective cryopreservation of all embryos with subsequent cryothaw embryo transfer in patients at risk for ovarian hyperstimulation syndrome reduces the risk of adverse obstetric outcomes: a preliminary study” by Imudia et al.
Reflections on “Serum insulin-like factor 3 is highly correlated with intratesticular testosterone in normal men with acute, experimental gonadotropin deficiency stimulated with low-dose human chorionic gonadotropin: a randomized, controlled trial” by Roth et al.
Evidence indicates that vitrification and warming of unfertilized oocytes followed by fertilization, commonly by intracytoplasmic sperm injection (ICSI), result in subsequent pregnancy rates which are acceptable and this technique should no longer be considered experimental.
