Abstract
Teratozoospermia is a rare disease associated with male infertility. Several recurrent genetic mutations have been reported to be associated with abnormal sperm morphology, but the genetic basis of tapered-head sperm is not well understood. In this study, whole-exome sequencing (WES) identified a homozygous WD repeat domain 12 (WDR12; p.Ser162Ala/c.484T>G) variant in an infertile patient with tapered-head spermatozoa from a consanguineous Chinese family. Bioinformatic analysis predicted this mutation to be a pathogenic variant. To verify the effect of this variant, we analyzed WDR12 protein expression in spermatozoa of the patient and a control individual, as well as in the 293T cell line, by Western blot analysis, and found that WDR12 expression was significantly downregulated. To understand the role of normal WDR12, we evaluated its mRNA and protein expression in mice at different ages. We observed that WDR12 expression was increased in pachytene spermatocytes, with intense staining visible in round spermatid nuclei. Based on these results, the data suggest that the rare biallelic pathogenic missense variant (p.Ser162Ala/c.484T>G) in the WDR12 gene is associated with tapered-head spermatozoa. In addition, after intracytoplasmic sperm injection (ICSI), a successful pregnancy was achieved. This finding indicates that infertility associated with this WDR12 homozygous mutation can be overcome by ICSI. The present results may provide novel insights into understanding the molecular mechanisms of male infertility.

Effects of chemotherapeutic agents on male germ cells and possible ameliorating impact of antioxidants. Biomed Pharmacother 2021; 142:112040. [PMID: 34416630 DOI: 10.1016/j.biopha.2021.112040] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2021] [Revised: 07/16/2021] [Accepted: 08/07/2021] [Indexed: 11/22/2022] Open
Abstract
Treatment of cancer in young adults is associated with several side effects, particularly in the reproductive system. Detrimental effects of chemotherapy on the germ cells depend on many factors including primary semen parameters, the way of drug administration, the kind and dose of chemotherapeutic regimens, and the phase of spermatogenesis during the time of drug administration. Lack of appropriate fertility preservation treatments particularly in the affected children necessitates the introduction of methods to amend the harmful effects of chemotherapeutic agents on male germ cells. Several studies have assessed the toxic effects of chemotherapeutic agents in rodent models and tested a number of antioxidants to evaluate their possible impact on the preservation of sperm cells. In the present manuscript, we describe the effects of the mostly investigated chemotherapeutic drugs in this regard i.e., cisplatin, doxorubicin, paclitaxel, 5-fluorouracil, and cyclophosphamide. As several in vivo and in vitro studies have shown the impact of antioxidants on chemotherapy-induced damage of sperms, we also describe the protective effects of antioxidants in this regard.

Abstract
This study aimed to evaluate the effect of N-acetyl cysteine on the male reproductive system and consensus and classification of data found from previous studies. It is undeniable that N-acetyl cysteine as a powerful antioxidant compound can medicate many diseases such as cardiovascular, kidney, liver and reproductive system disorders. With the increasing environmental pollution that has a direct adverse effect on male fertility, the use of this compound is able to positively function on human fertility health. In this study, we have been collected the main data of scientific articles (1994-2020) about N-acetyl cysteine effects. By searching in the scientific databases of PubMed, Google Scholar, Science Direct, Wiley and Web of Science, related articles were extracted. As a result, all observations have confirmed that N-acetyl cysteine can improve and normalise the spermatogenesis in the male reproduction system.

INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2020; 14:171-175. [PMID: 33098382 PMCID: PMC7604699 DOI: 10.22074/ijfs.2020.44411] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/14/2019] [Accepted: 05/11/2020] [Indexed: 12/15/2022]
Abstract
Background One of the important factor associated with male infertility is high production of reactive oxygen species (ROS).
The main function of Nuclear factor erythroid 2-related factor 2 (NRF2) is to activate the cellular anti-
oxidant response by inducing the transcription of a wide array of genes that can combat the harmful effects of factors
such as oxidative stress. The purpose of this study was to evaluate the effect of N-acetyl-L-cysteine (NAC), as an
antioxidant drug, on NRF2 Gene Expression in Asthenoteratozoospermia Men. Materials and Methods In this randomized, blinded clinical trial study, included 50 infertile men with asthenoteratozoo-
spermia, who received NAC (600 mg, three times daily). Sperm parameters analyzed according to the world health organiza-
tion (WHO; 2010). Sperm DNA fragmentation, relative NRF2 expression, and seminal plasma level of antioxidant enzymes
were measured by TUNEL assay, reverse transcription polymerase chain reaction (RT-PCR) and ELISA test, respectively.
Results After NAC treatment, findings showed a significant increase in sperm concentration and motility compared
to pre-treatment status, whereas the percentage of abnormal morphology and DNA fragmentation was significantly
decreased (P<0.05). A significant improvement in expression of NRF2 gene and antioxidant enzyme levels were ob-
served compared to pre-treatment by NAC (P<0.05). Significant correlations were observed between NRF2 mRNA
expression level, specific sperm parameters and level of antioxidant enzymes (P<0.05). Conclusion The results demonstrated that NAC oral supplementation protected against oxidative stress by enhancing
NRF2 expression. This could improve semen parameters quality parameters in asthenoteratozoospermia men (Regis-
tration number: IRCT20170830035998N4).

Reprod Biomed Online 2020; 40:856-866. [PMID: 32376314 DOI: 10.1016/j.rbmo.2020.01.029] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 12/31/2019] [Accepted: 01/30/2020] [Indexed: 01/07/2023]
Abstract
RESEARCH QUESTION A previous study showed that N-acetylcysteine (NAC), used after in-vitro exposure to the gonadotoxic chemotherapeutic drug etoposide, has the ability to decrease DNA damage in human spermatozoa; however, it showed no benefit when used before exposure. This study aimed to evaluate the impact of the NAC on the preservation of sperm quality during in-vitro exposure to etoposide. DESIGN Twenty semen samples were submitted to four experimental conditions: control, NAC-only incubation, etoposide-only incubation, and concomitant etoposide and NAC incubation. After in-vitro incubation, semen parameters, sperm chromatin condensation, sperm DNA fragmentation, sperm oxidative stress and sperm metabolism were used to evaluate the role of NAC in protecting human spermatozoa from etoposide. RESULTS Etoposide did not affect semen parameters, nor did it cause sperm oxidative damage or alterations in glycolytic profile. However, it induced chromatin decondensation and DNA fragmentation, which were fully prevented by NAC. CONCLUSIONS NAC was able to protect sperm DNA integrity during etoposide treatment in vitro, suggesting that NAC may be useful as an adjuvant agent in preserving male fertility during chemotherapy treatments.
