Oxidative stress (OS) affects men’s health and impairs spermatogenesis. Micronutrient antioxidants are available for male infertility as complemental support; however, their efficacy remains debatable. This study aimed to investigate whether can help reduce sperm OS improve semen analysis quality. We included 171 partners of couples planning undergo assisted reproductive technology (ART). Male partners, aged 29–41 years, intending conceive were self-selected take daily (n = 84) containing...
Repeated and dramatic pregnancy-induced uterine enlargement remodeling throughout reproductive life suggests the existence of smooth muscle stem/progenitor cells. The aim this study was to isolate characterize stem/progenitor-like cells from human myometrium through identification specific surface markers. We here identify CD49f CD34 as markers permit selection cell-like population show that CD45– CD31– glycophorin A– CD49f+ CD34+ myometrial exhibit stem properties. These include side...
Homocysteine is an amino acid naturally produced in the body and metabolized via methionine cycle. High homocysteine levels can increase risk of infertility pregnancy complications, such as preeclampsia, preterm delivery, miscarriage, low birth weight. Preconceptional may be reduced by taking folic supplements to reduce complications. This cross-sectional, hospital-based study was conducted examine role 1060 infertile women with a history IVF/intracytoplasmic sperm injection (ICSI) failure....
Background A number of laboratory tests have been developed to determine properties spermatozoa quality but few adopted into routine clinical use in place the WHO semen analysis. We investigated whether Atp6v0a2 (a2 isoform vacuolar ATPase) is associated with abnormal and changes chemokine-cytokine profiles infertile men. Patients Methods Semen samples were collected from 35 healthy donors men at Andrology August 2011 June 2012. The levels mRNA protein, its localization determined. a2NTD...
Abstract Introduction Laparoscopic surgery is a minimally invasive surgery, and the rate of postoperative adhesions low. Although Seprafilm® helps to reduce adhesions, its application in abdominal cavity during laparoscopic difficult because material. Therefore, we propose an easy method for applying this adhesion barrier. Materials Surgical Technique The Seprafilm cut into four equal pieces. pieces are stacked, firmly folded twice, grasped with forceps. reducer sleeve slid over bundle...
Abstract Background Endometrial receptivity array (ERA) is used to determine the timing of embryo transfer (ET) synchronized with window implantation (WOI). The effectiveness and evaluation ERAs in women recurrent failure remain controversial. We report case a patient that raises issue reproducibility ERA tests. Case A 36-year-old Japanese woman secondary infertility who had previously given birth failed conceive after three frozen-thawed (FET) cycles. An test was conducted confirm WOI....
This study aimed to ascertain the current status of Japanese sperm banking for young cancer patients. During 2015, we mailed directors 695 institutes where cryopreservation might be performed with questionnaires requesting information on number patients, age, precryopreservation chemotherapy, semen analyses results and diagnoses, success rate, causes unsuccessful cryopreservation. Of these institutes, 92 had cryopreserved before chemotherapy within period. In all, 820 patients (237...
