Repeated vitrification/warming of human sperm gives better results than repeated slow programmable freezing.
In this study, we compared the effects of repeated freezing/thawing of human sperm by our in-house method of rapid freezing with slow programmable freezing. Sperm samples from 11 normozoospermic subjects were processed through density gradients and divided into three aliquots: non-frozen, rapid freezing and slow programmable freezing. Sperm in the rapid freezing group had better motility and vi...
متن کاملEvaluation of human sperm function after repeated freezing and thawing.
Sperm storage via freezing has been useful for men who have difficulty masturbating during assisted reproductive technology (ART) programs and before impotency caused by chemotherapy, vasectomy, and other procedures. Studies were undertaken to evaluate the extent of cryoinjury to sperm after repeated freezing and thawing. The results showed that normozoospermic and oligozoospermic sperm survive...
متن کاملRepeated onabotulinumtoxin-a injections provide better results than single injection in treatment of painful bladder syndrome.
BACKGROUND Onabotulinumtoxin-A (BoNT-A) is effective for the treatment of interstitial cystitis/painful bladder syndrome (IC/PBS). However, long-term follow-up does not show successful outcome after a single injection. OBJECTIVES To evaluate the efficacy and safety of repeated intravesical BoNT-A injections for treatment of IC/PBS and compare the success rates among patient groups receiving d...
متن کاملHuman Breast Milk Provides Better Antioxidant Capacity than Infant Formula
Human milk contains all of the constituents that are required for the optimal growth and development of a neonate. It supports the development of brain, immune, and physiological systems. This study aimed to consider the significance of breast milk in preventing oxidative stress by comparing total antioxidant capacity (TAC) in breast and formula milk for premature infants, demonstrating the rel...
