Spermatozoa retrieved from the testis of men with high levels of sperm DNA fragmentation (SDF) in the neat semen tend to have better DNA quality. Given the negative impact of SDF on the outcomes of Assisted Reproductive Technology (ART), an increased interest has emerged about the use of testicular sperm for intracytoplasmic sperm injection (Testi-ICSI). In this article, we used a SWOT (strengths, weaknesses, opportunities, and threats) analysis to summarize the advantages and drawbacks of this intervention...

OBJECTIVE: To evaluate whether there is a synergistic effect of varicocele and smoking status on semen parameters. METHODS: A retrospective evaluation of 715 men attending an infertility clinic between 2001 and 2009 was carried out. The presence of a varicocele was determined by clinical examination and cigarette smoking habits were documented allowing patients to be divided into 4 groups: non-smokers (n = 369), mild smokers (n = 186, 1-10 cigarettes/day), moderate smokers (n = 129, 10-20 cigarettes/day) and heavy smokers (n = 31, over 20 cigarettes/day)...

Many genetic alterations have been identified to aid in understanding the genetic basis of male infertility, however, the cause of 30% of male infertility remains unknown. Some studies indicated that subdeletions of Y chromosome may be a reason for male infertility caused by testicular failure. In this regard, we aimed to investigate frequency of AZFc region subdeletions and their clinical effects in patients with idiopathic infertility. A total of 333 male infertile patients with non-obstructive azoospermia (NOA) or oligoasthenoteratozoospermia (OAT), and 87 normozoospermic controls were screened to detect gr/gr, b1/b3 and b2/b3 subdeletions...

Androgens and estrogens play a key role regarding sexual life and reproduction. Along with hypotestosteronemia, obese men exhibit a 2-fold increase in estradiol concentration, adversely infl uencing these parameters. Estrogens and adipokines also infl uence bone metabolism, exerting a direct effect on vitamin D, calcium homeostasis and bone health. Bariatric procedures normalize some sex hormones, and may reverse several obesity-related conditions. Estrogens levels may remain elevated postoperatively, and despite its protective effect on the skeleton, bariatric patients are more prone to fractures when compared to the general population...

STUDY QUESTION: Can 1H Magnetic Resonance Spectroscopy (MRS) be used to obtain information about the molecules and metabolites in live human spermatozoa? SUMMARY ANSWER: Percoll-based density gradient centrifugation (DGC) followed by a further two washing steps, yielded enough sperm with minimal contamination (<0.01%) from seminal fluid to permit effective MRS which detected significant differences (p < 0.05) in the choline/glycerophosphocholine, lipid and lactate regions of the 1H MRS spectrum between sperm in the pellet and those from the 40/80% interface...

In a prospective study, the outcomes of microsurgical varicocelectomy in men with primary versus secondary infertility were compared. Ninety-two infertile men with a varicocele were included. They were classified into those with primary infertility (n = 57) and secondary infertility (n = 35). Clinical data, semen parameters and scrotal ultrasound finding were available for all patients and microsurgical varicocelectomy was performed on all of them. Spontaneous pregnancy rates and improvement in semen parameters in those men with primary versus secondary infertility were recorded 1 year after surgery...

Chlamydia trachomatis is considered as the bacterium that is more sexually transmitted as cause of male urethritis, epididymitis, orchitis and infertility. A total of 116 semen samples of men whose couples are infertile women were analysed. The quality of the semen was measured by standard procedures recommended by WHO while C. trachomatis was detected by the PCR assay. Thirty-seven semen samples were positive for C. trachomatis (31.9%). Regarding semen analysis, no different values were observed between positive and negative samples to C...

We evaluate the association between genetic polymorphisms of XRCC5 VNTR, XRCC6 -61C>G, and XRCC7 6721G>T with male infertility susceptibility. A total of 392 men including 178 infertile males (102 idiopathic azoospermia and 76 severe oligozoospermia) and 214 healthy controls were recruited. XRCC6 -61C>G and XRCC7 6721G>T genotyping was performed by PCR-RFLP whereas XRCC5 VNTR was performed by PCR. The 2R allele and 2R allele carriers of XRCC5 VNTR polymorphism significantly decreased risk of male infertility...

Semen analysis lacks a functional component and best identifies extreme cases of infertility. The ganglioside GM1 is known to have functional roles during capacitation and acrosome exocytosis. Here, we assessed whether GM1 localization patterns (Cap-Score™) correspond with male fertility in different settings: Study 1 involved couples pursuing assisted reproduction in a tertiary care fertility clinic, while Study 2 involved men with known fertility versus those questioning their fertility at a local urology center...

PURPOSE OF REVIEW: Due to the fact that the Zika virus can be sexually transmitted, there is a potential risk for disease transmission at several stages of assisted reproduction. Such a possibility poses a serious challenge to couples pursing fertility with reproductive technologies. Here, we discuss what is known regarding Zika virus infection with respect to sexual transmission and correlate this knowledge with recent recommendations in the realm of infertility treatment. RECENT FINDINGS: Zika virus can be transmitted from infected men and women through vaginal, oral or anal intercourse...

Varicocoele is a common cause of male infertility. We undertook a population-based cross-sectional study to evaluate the prevalence of varicocoele among rural men in eastern China and its association with body mass index. A total of 39,559 rural men in six counties in Beijing, Guangdong and Shandong provinces were recruited from 2011 to 2012. The presence and severity of varicocoele were measured by physical examinations. Univariate and multivariate logistic regression models were constructed to assess the association between varicocoele and body mass index after adjusting for possible confounders...

Recently, the cohort of men from the European Male Ageing Study has been stratified into different categories distinguishing primary, secondary and compensated hypogonadism. A similar classification has not yet been applied to the infertile population. We performed a cross-sectional study enrolling 786 consecutive Caucasian-European infertile men segregated into eugonadal [normal serum total testosterone (≥3.03 ng/mL) and normal luteinizing hormone (≤9.4 mU/mL)], secondary (low total testosterone, low/normal luteinizing hormone), primary (low total testosterone, elevated luteinizing hormone) and compensated hypogonadism (normal total testosterone; elevated luteinizing hormone)...

REVIEW
Gulam Bahadur, Roy Homburg, Ansam Al-Habib
This review addresses the misplaced facts about the IUI procedure within a lucrative fertility industry. Evidence suggests IUI must be a first-line treatment option for most couples except in cases of bilateral tubal blockage and severe oligozoospermia. We introduce the concept of using 'consecutive ejaculation' in men with subfertility and one which can radically alter the male infertility definition, thereby providing a new approach to examining and managing male factor infertility. The review also explores various aspects affecting the IUI procedure, its determinants of success, risks and areas for future improvements...

Sperm motility notably depends on the structural integrity of the flagellum and the regulation of microtubule dynamics. Although researchers have started to use "omics" techniques to characterize the human sperm's molecular landscape, the constituents responsible for the assembly, organization, and dynamics of the flagellum microtubule have yet to be fully defined. In this study, we defined a core set of 116 gene products associated with the human sperm microtubulome (including products potentially involved in abnormal ciliary phenotypes and male infertility disorders)...

Isolated follicle stimulating hormone (FSH) deficiency due to mutations in FSHβ is an extremely rare autosomal recessive disease that has only been reported in ten patients to date. Symptoms of the disease include amenorrhoea and hypogonadism in women and azoospermia and normal testosterone levels in men. This study describes a Chinese male patient who presented with cryptorchidism and infertility. His serum hormonal profile revealed low FSH, elevated LH and normal testosterone levels. Sequence analysis identified a novel homozygous mutation in the FSHβ gene (c...
