ABSTRACT: This study was aimed at determining, with homologous mouse gametes, whether a level of membrane lipid peroxidation insufficient to affect sperm motility parameters can alter fertilizing potential. The addition ferrous ions and ascorbic acid (Fe 2+ / Asc) suspensions increases the formation thiobarbituric acid‐reactive substances (TBARS), an indicator peroxide breakdown products, without significantly affecting sulfhydryl groups. In presence Fe /Asc concentrations above >0.4/2.0...
To examine the effect of melatonin on in vitro fertilization and embryonic development, mouse embryos after insemination were cultured a physiological medium with or without melatonin. Melatonin increased rate significantly at concentration between 10(-6) 10(-4) M (27.6 vs. 43.9 40.4%, P < 0.01). Furthermore, significant increase reaching four-cell stage (16.0 26.7%, 0.01), eight-cell (12.1 25.8 23.5%, blastulation (8.9 23.5 17.5%, 0.01) was observed when containing 10(-8) These results...
Six years after the first edition of The Guideline for Gynecological Practice, which was jointly edited by Japan Society Obstetrics and Gynecology Association Obstetricians Gynecologists, third revised published in 2017. 2017 Guidelines includes 10 additional clinical questions (CQ), brings total to 95 CQ (12 on infectious disease, 28 oncology benign tumors, 27 endocrinology infertility healthcare women). Currently a consensus has been reached therefore objective this report is present...
Abstract Problem We aimed to compare the therapeutic effects of hysteroscopic polypectomy with and without doxycycline treatment on chronic endometritis (CE) endometrial polyps. Method study: Design A cross‐sectional study was conducted 267 infertile patients, whom 243 were recruited, who underwent between March 2019 2020. During surgery, specimens for immunohistochemistry analysis plasma cell marker CD138 intrauterine bacterial culture obtained diagnose CE, prevalence CE analyzed. Of 222...
Objective To elucidate the risk factors associated with resignation from work of Japanese women undergoing infertility treatment. Methods A total 1727 female patients who attended a private fertility clinic in Japan participated Japan-Female Employment and Mental health Assisted reproductive technology study. Questions related to demographic, clinical socioeconomic characteristics were employed questionnaire. Out patients, 1075 working at time initiating treatment felt incompatible included...
Abstract Purpose The purpose was to establish a mild ovarian stimulation protocol that would help assisted reproductive technology (ART) units avoid scheduling on weekends. Methods This directed patients take 50 mg/day of clomiphene citrate between days 3 and 7 the menstrual cycle: 225 IU recombinant follicle‐stimulating hormone (rec‐FSH) were administered 3, 5 7; human chorionic gonadotropin (hCG) day 9; and, oocyte pick‐up (OPU) planned for 11. From October 2008 through 2009, 514 women...
The endometriosis fertility index (EFI) is a novel for predicting pregnancy after surgery. We investigated the utility of EFI ability to conceive without assisted reproductive technology (ART) treatment laparoscopic surgery.From July 2011 through December 2012, we recruited 133 infertile patients who underwent laparoscopy, and was calculated. After surgery, 55 achieved ART treatment. evaluated factors that predicted naturally successful compared them between pregnant non-pregnant subjects.On...
We examined the current status of human T-cell leukemia virus type 1 (HTLV-1) carrier in Japanese pregnant women, according to results HTLV-1 screening and confirmation tests women who gave birth Japan 2011. requested 2642 obstetrical facilities provide information 71.3% them responded. Considering response rate implementation tests, number was estimated be 1620 (0.16%) per year.
We aimed to determine the frequency of endometrial cancer in infertile women undergoing hysteroscopic polypectomy for polyps.A total 1035 patients who underwent office-based at Sugiyama Clinic Marunouchi between July 2011 and October 2015 were eligible this retrospective study. All had been diagnosed with polyps via hysterofiberscopy prior operation, they using a resectoscope monopolar resection. Surgical specimens examined histopathologically. Characteristics on histopathological...
Abstract Purpose To determine whether embryos cultured with a low oxygen level (2%) brought about beneficial effects on the outcome of ART. Methods This is sequential case–control embryo‐culture study. Embryos were either gas mixture containing 2% O 2 , 5% CO and 93% N (low‐oxygen group) or 90% (conventional group). From January 2008 to September 2008, 873 fertilized oocytes obtained from 250 patients in low‐oxygen group October March 2009, 730 213 conventional group. The outcomes ART...
Observation of the microvasculature using narrow band imaging (NBI) with magnifying endoscopy is useful for diagnosing superficial squamous cell carcinoma. Increased vascular density indicative cancer, but not many studies have reported differences between cancerous and noncancerous areas based on an objective comparison. We observed specimens endoscopic submucosal dissection (ESD) NBI magnification, determined areas. A total 25 lesions esophageal carcinoma that were dissected en bloc by ESD...
Since September 2010, in Japan serological screening for the detection of human T-cell leukemia virus type 1 (HTLV-1) antibodies can be performed all women during pregnancy with Japanese public funds strategies prevention HTLV-1 vertical transmission, because Japan, especially Kyushu area, has been reported to one areas highest prevalence world [1, 2]. In our previous study [3], we examined carrier pregnant according implement rate and results confirmation tests who gave births 2011. The...
Abstract Background Few reports have presented an overall view of pregnant women with coronavirus disease 2019 (COVID-19) across entire country and throughout the gestation period. Furthermore, no such are available for Japan. We examined clinical characteristics outcomes COVID‑19 on a national scale in Methods A nationwide questionnaire-based survey all 2,185 maternity services Japan was conducted between July August 2020. Information regarding maternal epidemiological, clinical, treatment,...
The concentrations of noradrenaline in preovulatory follicular fluid obtained from women undergoing vitro fertilization were determined by high-performance liquid chromatography with fluorometric detection and compared those peripheral plasma concurrently. All the samples contained at substantially higher than corresponding samples. A positive correlation was found between levels each woman (n = 11; r 0.952; p < 0.001). However, there no significant difference aspirated follicles or without...
Chlamydia trachomatis (CT) infection in pregnancy can cause maternal disease, adverse outcomes, and neonatal disease [1-6]. In general, approximately 80% of CT infected women are asymptomatic or minimally symptomatic. There-fore, screening is the only means to effectively identify infec-tions [2]. Japan, pregnant routinely tested for with Japanese public funds. According guide-lines obstetrical practice Japan [7], obstetri-cians must provide a test detection pre-vention diagnose urogenital...
Abstract Aim To determine the efficacy of prostaglandin administration during proliferative phase in order to improve pregnancy rates following frozen embryo transfer a hormone replacement cycle ( HRC ). Methods From S eptember 2010 through M arch 2012, patients n = 135) were recruited who had undergone oocyte retrieval stimulation with clomiphene and deferred fresh ET ) due thin uterine endometrium.

To confirm whether women who choose to have one fresh embryo transferred and frozen-and-thawed when needed can dramatically reduce the possibility of a multifetal pregnancy while giving themselves better chance achieving pregnancy.We enrolled 685 patients were undergoing assisted reproductive technology (ART) treatment at our clinic between January 2005 December 2008. None had history ART treatment, they received either double-embryo transfer (DET) or single-embryo (SET) during this period....
