Herein, we report the clinical outcomes following intracytoplasmic sperm injection (ICSI) with cryopiece cryopreserved rare human spermatozoa from severe male factor infertility patients. We established a novel cryopiece system on the basis of previous studies. In this study, 126 spermatozoa from four patients with non-obstructiveazoospermia (NOA) or severe oligozoospermia were stored in cryopiece and then thawed on the day of the oocyte retrieval, 88 (83%) spermatozoa were recovered with a 47.5% (38 of 80) motile rate...

Genetic mechanisms are implicated in some cases of male infertility. Recently, it was demonstrated that male mice lacking the gene for RAD21L exhibited azoospermia caused by meiotic arrest. Mouse RAD21L is a functionally relevant meiotic α-kleisin that is essential for male fertility. Therefore, we hypothesized that RAD21L mutations or polymorphisms may be associated with male infertility, especially azoospermia secondary to meiotic arrest. To determine if RAD21L defects are associated with azoospermia in groups of patients with meiotic arrest, we performed direct sequencing of the RAD21L coding regions in 38 Japanese patients with meiotic arrest and in 200 normal controls...

The purpose of this study was to compare the prevalence of pelvic floor dysfunction (PFD) symptoms in patients with and without polycystic ovary syndrome (PCOS) and among different PCOS phenotypes. This was a case-control study. All participants were assessed using ultrasonography to determine the presence or absence of polycystic ovaries (PCO) and allocated to the case or control group (having healthy females whose husbands were diagnosed with male infertility). The case group was then further subdivided into the three phenotypes according to the presence or absence of menstrual dysfunction (M), hyperandrogenism (HA) and PCO on ultrasonography...

The use of intra-cytoplasmic sperm injection (ICSI) has increased significantly worldwide, often chosen instead of in vitro fertilization (IVF), yet long-term health outcomes are unknown and health differences between ICSI and IVF conceptions have not been comprehensively assessed. A systematic review of health outcomes of ICSI-conceived offspring beyond the neonatal period compared to IVF-conceived offspring was carried out. PubMed, OVID Medline/Embase, Informit, Web of Science and Proquest databases were searched on 9 November 2016 for studies reporting on health outcomes in ICSI-conceived offspring beyond 28 days after birth...

Zinc finger protein 185 (ZNF185) belongs to the ZNF family and is involved in cell proliferation and differentiation. To the best of our knowledge, the association between ZNF185 and male reproduction is unknown. In the present study, the expression and localization of ZNF185 in mouse testis, as well as its role in testosterone secretion, cell cycle progression and apoptosis of mouse Leydig cells were investigated. The results of the immunofluorescence analysis indicated that ZNF185 was highly expressed in Leydig cells of the mouse testis, and primarily localized in the cytoplasm...

INTRODUCTION: From the previously published literature on the relationship between obesity and infertility, it is clear that male obesity negatively impacts semen quality. Accordingly, this study was conducted to determine whether regular exercise may improve semen quality in sedentary obese adults. MATERIAL AND METHODS: Ninety obese adults were randomly allocated to the intervention (n = 45) or control group (n = 45). Participants in the intervention group performed a 16-week aerobic training program in a treadmill, three sessions per week, consisting of a warm-up (10-15 minutes), 35-50 minutes treadmill exercise (increasing five minutes per four weeks) at a work intensity of 50-65% of peak heart rate (increasing a 5% per four weeks) and cooling-down (5-10 minutes)...

BACKGROUND: Clomiphene is normally used in women with ovulatory dysfunction. In men, it is used off label in some cases of infertility. Psychological adverse effects are reported in women but very few in men. CASE: A 34 year-old man treated with clomiphene for oligoteratospermia presented anxiety, decreased appetite, and depressed mood making him unable to function properly at work, five days after initiation of therapy. Symptoms required reduction followed by discontinuation of treatment four days later because of absence of improvement...

PURPOSE: The functional role of the FSHR promoter -29G/A polymorphism (rs1394205) in men is not clear. Some studies failed to find a relationship between the FSHR -29G/A and follicle-stimulating hormone (FSH) levels and did not associate the SNP with male infertility. Only one study showed that the FSHR -29 SNP modulates serum FSH levels in Baltic young male cohort. Because the SNP -29G/A has to be shown to have a strong effect on in vitro transcription activity of the FSHR promoter and the activation of FSHR is necessary for a normal FSH function, this study was undertaken to assess whether the FSHR -29G/A SNP modulates the gonadal endocrine function in men...

OBJECTIVE: Intracytoplasmic sperm injection (ICSI) is commonly used during pre-implantation genetic diagnosis (PGD) in vitro fertilization (IVF), aiming to eliminate the risk of contamination from extraneous sperm DNA. Recently, ICSI "overuse" in non-male infertility has been doubted, since it does not offer an advantage over IVF. Prompted by the aforementioned observations, we sought to assess the accuracy of IVF vs ICSI in PGD cases, as might be reflected by a difference in the prevalence of discarded embryos as a consequent of parental contamination...
