Subendometrial myometrium exerts wave-like activity throughout the menstrual cycle, and uterine peristalsis is markedly reduced during the implantation phase. We hypothesized that abnormal uterine peristalsis has an adverse effect on the endometrial decidualization process. We conducted an in vitro culture experiment to investigate the effect of cyclic stretch on the morphological and biological endometrial decidual process.

Primary human endometrial stromal cells (HESCs) were isolated from hysterectomy specimens and incubated with or without 8-bromo-cyclic adenosine monophosphate (8-br-cAMP) and medroxyprogesterone acetate (MPA) for 3days. After decidualization, cultures were continued for 24hours with or without cyclic stretch using a computer-operated cell tension system.

Cyclic stretch significantly repressed expression of decidual markers including insulin-like growth factor-binding protein 1 (
), prolactin (
), forkhead box O1 (
), and
on decidualized HESCs. In addition, cyclic stretch of decidualized HESCs affected the decidual morphological phenotype to an elongated shape. The alternation of F-actin localization in decidualized HESCs was not observed in response to cyclic stretch.

These data suggest that cyclic stretch inhibits the morphological and biological decidual process of HESCs. Our findings imply that uterine abnormal contractions during the implantation period impair endometrial decidualization and contribute to infertility.

Cryptorchidism is one of the most common causes of non-obstructive azoospermia (NOA) in adulthood. Even if early orchidopexy is performed to preserve fertility potential, some patients still suffer from azoospermia. Fertility potential is significantly lower in bilateral than unilateral cryptorchidism. The aims of this study were to identify clinical parameters that predict the likely success of sperm recovery by microscopic testicular sperm extraction (micro-TESE) and also the likely outcome of intracytoplasmic sperm injection using sperm from NOA patients who submitted to bilateral orchidopexy.

Fifty-two NOA patients with a history of bilateral cryptorchidism underwent micro-TESE. The following clinical parameters were evaluated as predictive factors for successful sperm recovery age at micro-TESE; age at orchidopexy; period from orchidopexy to micro-TESE; luteinizing hormone (LH); follicle-stimulating hormone (FSH); testosterone; average testicular volume; and body mass index.

In the successful sperm retrieval group, average testicular volume was significantly greater, while serum LH and FSH, and body mass index were significantly lower. In find more , average testicular volume was positively correlated with successful sperm recovery.

Our results indicate that testicular volume in NOA patients with bilateral cryptorchidism is a predictor for successful sperm recovery.

In the present study, I evaluated the usefulness of Medium RD, with mixed RPMI1640 and Dulbecco's modified Eagle's medium (11, v/v), as a chemically defined medium for in vitro maturation (IVM) of bovine oocytes.

In vitro maturation was performed in 10mmol/L HEPES-buffered TCM199 (mTCM199), 10mmol/L HEPES-buffered Medium RD (mRD), and mTCM199 supplemented with fetal bovine serum fraction (mTCM199+FBS fraction) that served as control. Cumulus-oocyte complexes were matured for 24hours in three different media supplemented with follicle-stimulating hormone, estradiol-17β, and polyvinylpyrrolidone. Nuclear maturation of oocytes, their developmental competence into blastocysts after in vitro fertilization (IVF) and mitochondrial distribution in oocytes were investigated.

There was no difference in the ratio of matured oocytes regardless of IVM media. The percentage of morula stage was higher in mRD than in mTCM199 group (
<.05) at 120-144hours after IVF, although the blastocyst rates between groups were not significantly different at 168-216hours. IVM in mRD increased the percentage of oocytes with diffused mitochondrial distribution compared with the immature and mTCM199 and had similar percentage of oocytes in mTCM199+FBS fraction.

Medium RD would be useful as a chemically defined medium for IVM of bovine oocytes.

Assisted reproductive technology (ART) is a widely applied fertility treatment. However, the developmental competence of aged oocytes from women of a late reproductive age is seriously reduced and the aged oocytes often fail in fertilization even when ART is used. To resolve this problem, we examined usefulness of a new method "the metaphase II spindle transfer (MESI)" as ART using mouse oocytes.

This work was composed of two experiments. First, 24hours after collection, embryos from oocytes (1-day-old oocytes, called postovulatory-aged oocytes), were observed, after intracytoplasmic sperm injection (ICSI), and it was found that they were not able to reach the blastocyst stage. #link# Next, the metaphase II chromosome-spindle complexes from 1-day-old oocytes were injected into cytoplasts from oocytes just collected, using piezo pulses to generate reconstructed oocytes. This procedure was named metaphase II spindle injection (MESI).

After ICSI, embryos from the reconstructed oocytes (32/105), which contained the genes of 1-day-old oocytes, were able to develop into the blastocyst stage. The fragmentation rate after ICSI was 28.6%. Thus, the developmental competence of 1-day-old oocytes was improved by MESI.

The MESI method has the potential to improve the success rate of infertility treatments for women of a late reproductive age.

The purpose of this study was to investigate the effectiveness of intrauterine administration of platelet-rich plasma (PRP) in frozen embryo transfer (FET) cycle in Japanese patients with a thin endometrium.

A prospective single-arm self-controlled trial was conducted in Japan. PRP administration was performed in 36 of the 39 eligible patients with a thin endometrium (≤7mm). Hormone replacement therapy (HRT) with estrogen was performed for 2 menstrual cycles, and PRP was administrated on the 10th and 12th days of the second HRT cycle. The endometrial thickness was evaluated on transvaginal ultrasonography by two physicians at every visit, one an attending physician and the other a specialist physician blinded to the date and timing of the sonography. FET was performed during the second HRT cycle after PRP administration.

After PRP administration, the mean (SD) endometrial thickness on the 14th day was significantly increased by 1.27mm (
<.001) and 0.72mm (
=.001) on the basis of the unblinded and blinded measurements, respectively. Of the 36 patients, 32 (88.9%) underwent FET. The clinical pregnancy rate was 15.6%. No adverse events occurred.

PRP therapy was safe and effective in increasing endometrial thickness improving possibly pregnancy rate.

It is still unclear whether endometrial injury (EI) has a beneficial effect on reproductive outcomes, and if so, the optimal procedure characteristics are not clear. All previous papers concluded that more research is needed, and as additional studies were recently published, the insights on EI have changed significantly.

Searches were conducted in MEDLINE, Embase, Web of Science, and Cochrane Library, to identify randomized controlled trials examining the EI effect on IVF outcomes in women at least one previous failed cycle.

2015 references were identified through database searching. Ultimately, 17 studies were included, involving 3016 patients. Clinical pregnancy rate (CPR) (RR=1.19, [95% CI 1.06-1.32],
=.003) and live birth rate (LBR) (RR=1.18, [95%CI 1.04-1.34],
=.009) were significantly improved after EI. Number of previous failed cycles, maternal age, and hysteroscopy were found to be relevant confounders. Higher CPR and LBR were found when EI was performed twice, while performing EI once did not significantly improve reproductive rates.

According to the present meta-analysis, EI may be offered to younger patients with few previous failed cycles and should be additionally studied in an RCT comparing different timing and more than one EI before treatment.

Extra-pelvic endometriosis is a rare type of endometriosis, which occurs in a distant site from gynecological organs. The diagnosis of extra-pelvic endometriosis can be extremely challenging and may result in a delay in diagnosis. The main objective of this review was to characterize abdominal wall endometriosis (AWE) and thoracic endometriosis (TE).

The authors performed a literature search to provide an overview of AWE and TE, which are the major types of extra-pelvic endometriosis.

Abdominal wall endometriosis includes scar endometriosis secondary to the surgical wound and spontaneous AWE, most of which occur in the umbilicus or groin. Surgical treatment appeared to be effective for AWE. Case reports indicated that the diagnosis and treatment of catamenial pneumothorax or endometriosis-related pneumothorax (CP/ERP) are challenging, and a combination of surgery and postoperative hormonal therapy is essential. link2 Further, catamenial hemoptysis (CH) can be adequately managed by hormonal treatment, unlike CP/ERP.

Evidence-based approaches to diagnosis and treatment of extra-pelvic endometriosis remain immature given the low prevalence and limited quality of research available in the literature. To gain a better understanding of extra-pelvic endometriosis, it would be advisable to develop a registry involving a multidisciplinary collaboration with gynecologists, general surgeons, and thoracic surgeons.

At present, one out of six couples is infertile, and in 50% of cases, infertility is attributed to male infertility factors. Genetic abnormalities are found in 10%-20% of patients showing severe spermatogenesis disorders, including non-obstructive azoospermia.

Literatures covering the relationship between male infertility and genetic disorders or chromosomal abnormalities were studied and summarized.

Genetic disorders, including Klinefelter syndrome, balanced reciprocal translocation, Robertsonian translocation, structural abnormalities in Y chromosome, XX male, azoospermic factor (AZF) deletions, and congenital bilateral absence of vas deferens were summarized and discussed from a practical point of view. Among them, understanding on AZF deletions significantly changed owing to advanced elucidation of their pathogenesis. link3 Due to its technical progress, AZF deletion test can reveal their delicate variations and predict the condition of spermatogenesis. Thirty-nine candidate genes possibly responsible for azoospermia have been identified in the last 10years owing to the advances in genome sequencing technologies.
