AbstractMale infertility is a condition that affects approximately 50% of infertile couples and about 30% of those couples have only male factor infertility identified. There has been speculation that male military service members may have an even greater lifetime prevalence of infertility as compared to the general population, but very few scientific publications focus on male factor infertility in the military population specifically. This review will discuss many of the unique considerations regarding male infertility in the military and highlight future opportunities for research. The military/federal health system has the potential to serve as a leader in both the delivery of health care for male factor infertility and in the clinical investigation into the etiologies of and treatments for male factor infertility.

Cross Cultural Studies

This study analyzes blogs about male-factor infertility posted on a Japanese blogsite on a certain day in April 2014. It focuses on an understudied topic and is the first study of Japanese male infertility based on blogs. The blog format afforded anonymity to the bloggers, and our sample of 97 adults yields the largest number of individual respondents of all cross-cultural studies cited in our literature review. We extract three major themes from the analysis of the blogs, offer suggestions for a redirection of family and infertility policy in Japan, and suggest lines for further research.

Objective: Infertility affects 15% of couples in fertile age. Male factor is a cause of infertility in almost half of cases, mainly due to oligoasthenoteratozoospermia (OAT). The purpose of this study is to review the effects of nutritional supplements as medical treatment for idiopathic male infertility. Material and methods: A Pub Med and Medline review of the published studies utilizing nutritional supplements for the treatment of male infertility has been performed. Results: Clinical trials on Vitamin E, Vitamin A, Vitamin C. Arginine, Carnitine, N-Acetyl-Carnitine, Glutathione, Coenzyme Q10, Selenium and Zinc were reviewed. Although there is a wide variability in selected population, dose regimen and final outcomes, nutritional supplements both alone and in combination seems to be able to improve semen parameters (sperm count, sperm motility and morphology) and pregnancy rate in infertile men. Conclusions: There are rising evidences from published randomized trials and systematic review suggesting that nutritional supplementation may improve semen parameters and the likelihood of pregnancy in men affected by OAT. This improvement, however, is not consistent and there is a wide variation in the treatment regimens used. Well designed and adequately powered RCTs are needed to better clarify the role of nutritional supplements as treatment for male infertility.

Background. Male infertility is a main clinical problem that affects about 7% of all men worldwide. Many patients with male infertility are caused by a reduced antioxidant capacity of semen. Several antioxidant supplements, especially vitamin E, are proposed to help male infertility treatment. This project was goaled to study the effects of oral synthetic vitamin E (400 IU/day) for eight weeks on betterment of semen parameters and pregnancy rate. Methods. After dropping the cases, 124 infertile couples with a male factor who were admitted to the IVF program were included. The male patients with idiopathic abnormal motility and/or morphology were randomized into two groups: 61 receiving vitamin E and 63 as the control group receiving placebo for eight weeks. The pretreatment semen parameters of both groups were compared with those of posttreatment. The pregnancy outcomes were considered between the two groups. Results. There were no significant differences statistically between before and after treatment in the term of sperm volume, count, motility, and morphology. Furthermore, the IVF outcomes of the two groups were not different significantly, either. Interestingly, the percent of normal sperm in the placebo group was significantly decreased after eight weeks. Conclusion. Vitamin E supplementation might neutralize free radical activity to keep sperm from more oxidative damages. Further studies regarding the influence of higher acceptable doses of vitamin E on semen characteristics and fertility rates are needed. This study was registered as a two-arm, blinded, randomized, placebo-controlled clinical trial (IRCTID: IRCT2014020616506N1, 2014-03-18).

Abstract Study question To investigate whether idiopathic male infertility may be due to the presence of histones in motile spermatozoa using a modified AB staining protocol. Summary answer No correlation between CMI in live motile spermatozoa, DNA Fragmentation Index (DFI) and other conventional seminal parameters were found in male infertile patients. What is known already The AB stain discriminates between lysine-rich histones and arginine/cysteine-rich protamines. Transition from histones to protamines during spermatogenesis remodels chromatin packaging and abnormalities in the substitution of those proteins maybe interfere with seminal parameters and affect male infertility. The correlation between CMI and seminal parameters is known, but little is knowledge about live and motile spermatozoa associated to CMI because literature report only spermatozoa fixation before staining. Sperm chromatin carries half of the genomic material to offspring. Spermatozoa nuclear status is crucial for balanced transmission to future generations, and histones modifications are directly involved in epigenetic mutations. Study design, size, duration Retrospective observational study of 77 men underwent to standard semen analysis, including the evaluation of CMI and DFI, enrolled from January to December 2020. Mean age of the men was 36.63±8.26 years old, sperm concentration 46.69±37.23 mill/mL, linear progressive motility 39.35±15.31%, normal morphology 6.42±3.40%, DFI 25.91±10.29%. 200 spermatozoa for evaluation of CMI and 300 for DFI were analyzed respectively. Participants/materials, setting, methods Semen samples of 77 patients were collected and analyzed according to 5th edition of WHO guidelines (2010) for examination of human semen. For the evaluation of CMI we performed a new modified protocol for AB stain directly in live spermatozoa. Dilution 1:1 fresh semen and Aniline Blue colorant were mixed and placed on a slide and examined in bright field microscopy x1000 magnification. DFI was evaluated using Sperm Chromatin Dispersion (SCD) test. Main results and the role of chance Of all spermatozoa analyzed, 82.58±29.98% were white, 17.17±17.21% were pale blue, and 28.53±21.09% were dark blue. By our modified protocol, directly in live spermatozoa, we correlated AB staining with motility and , surprisingly, all motile spermatozoa observed were not stained (white), while pale or dark blue spermatozoa resulted always immotile. For this reason, we have considered pale blue spermatozoa as AB positive, in disagreement with some authors. So, maybe, we should reconsider pale blue stained spermatozoa as abnormal. We also observed AB negative spermatozoa with morphological head, neck and tail defects, underlining the independence of these two parameters: nuclear status and morphology. We have observed no statistically significant differences between conventional semen parameters, DFI and CMI, so nuclear analysis seems to be independent parameters. The statistical analysis was performed by Matlab statistical toolbox version 2008 (MathWorks, Natick, MA, USA) for Windows at 32 bit; finally all tests with p-value (p) < 0.05 were considered significant. Attention should be paid to the evaluation of CMI not only in astenozoospermic patients, where a lower CMI is known, but also in normozoospermic infertile patients. Limitations, reasons for caution This is a preliminary observational study on a small number of normozoospermic or mild asthenozoospermic patients. The study should be considered as a pilot study. Future studies with higher number of samples are necessary in order to confirm the results obtained. Wider implications of the findings: This is the first study that reports AB staining on unfixed live spermatozoa with a modified protocol. Our study underlines the necessity of classify pale blue spermatozoa as AB positive. Further investigations are necessary. This is a starting point for future analysis to be carried out under the project EcoFoodFertility. Trial registration number Not applicable

Year 2000

Infertility affects 50 to 80 million people worldwide. Male factor is a cause of infertility in almost half of cases, mainly due to oligoasthenoteratozoospermia (OAT). With common diagnostic methods no cause can be found in approximately 30% of cases of male infertility due to OAT and these are considered idiopathic. Reactive oxygen species (ROS) play an important role in male infertility and are proved to be higher in infertile men; antioxidants could oppose their effect. The aim of this paper was to review the literature on clinical trials in the period from year 2000 to year 2013 studying the effects of various types of antioxidant supplements on basic and other sperm parameters and pregnancy rates in subfertile males with idiopathic OAT. The majority of studies were randomized and placebo controlled and confirmed beneficial effect of antioxidants on at least one of the semen parameters; the biggest effect was determined on sperm motility. In many of these trials combinations of more antioxidants were assessed. The optimal dosages of one or more antioxidants were not defined. We concluded that antioxidants play an important role in protecting semen from ROS and can improve basic sperm parameters in case of idiopathic OAT.

Defective Spermatogenesis

It is archaic to view male factor infertility today separately from in vitro fertilization (IVF) and treatment of the female partner. Oligoasthenozoospermia may be an inherited condition (most likely on the Y chromosome), and is refractory to any treatment of the male including hormones and varicocelectomy. IVF technology is the only justifiable approach for achieving a pregnancy in these couples. The reasons for this view and the suggested modern approach to couples with oligoasthenozoospermia are outlined in this review. However, obstructive azoospermia is different as it can be successfully corrected with microsurgery in over 90% of men. When it cannot be corrected, as in congenital absence of vas, microsurgical sperm retrieval combined with IVF can still be highly effective in producing pregnancy with sperm from the husband. The most important arena for research into male infertility in the next decade will be to map out the deletions on the Y chromosome that might result in defective spermatogenesis, and which probably cause most cases of non-obstructive male factor infertility.

Approximately 30–40% of couples seeking fertility treatments have male factor infertility. Their dysfunctions include azoospermia, oligozoospermia, asthenozoospermia and teratozoospermia. Those with azoospermia represent about 25% of the total, and of these about 30% have an obstructive process while the remaining have either primary or secondary testicular failure. In the obstructive azoospermia group, 25% of males have congenital bilateral absence of the vas deferens (CBAVD).
