Prediction of pregnancy by intrauterine insemination using CASA estimates and strict criteria in patients with male factor infertility
Hiroaki Shibahara,Hiromi Obara,Ayustawati,Yuki Hirano,Tatsuya Suzuki,Akiko Ohno,Satoru Takamizawa,Mitsuaki Suzuki +7 more
TL;DR: Three semen parameters including normal morphology before sperm separation, rapid and VCL after sperm separation were identified as predictors of pregnancy by IUI and would be helpful when counselling patients before they make the decision to proceed with in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI)-ET.
Journal Article
The in-vitro effects of nicotine, cotinine and leptin on sperm parameters analyzed by CASA system
Joursaraei S.Gh.A.,Hiroaki Shibahara,Ayustawati,Yuki Hirano,Y Shiraishi,A Khalatbari,Y R Yousefnia Pasha,Suzuki Mitsuaki +7 more
TL;DR: Nicotin and cotinin have negative effects on the sperm parameters but despite the positive effect of leptin, there is no correlation between leptin concentration in semen and its physical characteristics.
Journal ArticleDOI
Relationships between Chlamydia trachomatis antibody titers and Tubal pathology assessed using transvaginal hydrolaparoscopy in infertile women
Hiroaki Shibahara,Satoru Takamizawa,Yuki Hirano,Ayustawati,Yuji Takei,Hiroyuki Fujiwara,Saori Tamada,Ikuo Sato +7 more
TL;DR: This study was performed to investigate the relationships between Chlamydia trachomatis antibody titers and tubal pathology assessed using THL in infertile women and found THL is a less traumatic and more suitable outpatient procedure than diagnostic laparoscopy.
Journal ArticleDOI
Chemokine Bioactivity of RANTES is Elevated in the Sera of Infertile Women with Past Chlamydia trachomatis Infection
Hiroaki Shibahara,Yuki Hirano,Ayustawati,Kumiko Kikuchi,Akiyo Taneichi,Hiroyuki Fujiwara,Satoru Takamizawa,Ikuo Sato +7 more
TL;DR: This study was performed to clarify the relationship between chemokines in the sera of infertile women and past C.’trachomatis infection.
Journal ArticleDOI
Influence of endometrial thickness and pattern on pregnancy rates in in vitro fertilization‐embryo transfer
Ayustawati,Hiroaki Shibahara,Hiromi Obara,Yuki Hirano,Akiyo Taneichi,Tatsuya Suzuki,Satoru Takamizawa,Ikuo Sato +7 more
TL;DR: Endometrial thickness and pattern have no influence on the pregnancy rates in an IVF-ET cycle, but patients with triple-line endometrial pattern and group B endometrian thickness showed a better pregnancy outcome in the IVf-ET treatment.
