Abstract
BACKGROUND Since the 1970s, there has been a quantitative and qualitative decline in sperm parameters. The main hypothesis to explain such a rapid evolution is the involvement of environmental and behavioral phenomena. METHODS A bibliographic search limited to English and French literature in men published before 7/2023 was carried out on the links between fertility and pollution, xenobiotics, tobacco, narcotics, cannabis, alcohol, weight, sport, sedentary lifestyle, sleep and anabolics. RESULTS Profound changes in lifestyle have occurred over the past 50 years: reduced sleep time, sedentary lifestyle, dietary changes, tobacco consumption, use of narcotics and anabolics. These changes have a proven impact on spermogram parameters, and should be corrected in an effort to optimize reproductive health. Other environmental parameters: pollution, exposure to heavy metals, exposure to xenobiotics, phthalates and pesticides… will be more difficult to exclude from patients' daily lives, but deserve to be taken more into account. CONCLUSION This review should help the urologist to assess and counsel patients in order to improve their reproductive health. These factors should be routinely investigated in infertile men.

Sci Rep 2021; 11:18824. [PMID: 34552120 PMCID: PMC8458393 DOI: 10.1038/s41598-021-98036-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 08/25/2021] [Indexed: 02/08/2023] Open
Abstract
Akt and nuclear factor kappa B (NF-κB) signaling pathways are involved in germ cell apoptosis and inflammation after testicular heat stress (THS). We observed that after THS induced by the exposure of rat testes to 43 °C for 20 min, their weight decreased, the fraction of apoptotic testicular germ cells significantly increased, and the proliferation of germ cells was inhibited. In addition, THS lowered serum testosterone (T) level, whereas the levels of follicle stimulating hormone and luteinizing hormone were not significantly changed. The ultrastructure of the seminiferous tubules became abnormal after THS, the structure of the blood-testis barrier (BTB) became loose, and the Sertoli cells showed a trend of differentiation. The level of phosphorylated Akt was reduced, whereas the amount of phosphorylated NF-κB p65 was augmented by THS. Wuzi-Yanzong (WZYZ), a classic Chinese medicine prescription for the treatment of male reproductive dysfunctions, alleviated the changes induced by THS. In order to determine the mechanism of action of WZYZ, we investigated how this preparation modulated the levels of T, androgen receptor (AR), erythropoietin (EPO), EPO receptor, and Tyro-3, Axl, and Mer (TAM) family of tyrosine kinase receptors. We found that WZYZ activated the Akt pathway, inhibited the Toll-like receptor/MyD88/NF-κB pathway, and repaired the structure of BTB by regulating the levels of T, AR, TAM receptors, and EPO. In conclusion, these results suggest that WZYZ activates the Akt pathway and inhibits the NF-κB pathway by acting on the upstream regulators, thereby improving spermatogenesis deficit induced by THS.

Abstract
The purpose of this study was to determine the prevalence of spermogram abnormalities in men consulting for premarital screening and in infertile couples in Butembo. We conducted a retrospective descriptive study at the Graben University Diagnostic Center. The study population consisted of 890 male subjects aged 21-57 years, of whom 779 underwent prenuptial screening and 111 subjects fertility tests. The overall prevalence of spermogram anomalies in this population was 25.8%, corresponding to a total incidence of 22.9% of premarital consultants and 46,0% of males in infertile couples. Mean pH was: 7.22+/- 0.22. The average volume of semen collected was: 2.56 +/- 1.41 ml. Abnormalities were detected in all spermogram parameters, with a predominance of abnormalities in the same subject (86.5%), mainly in oligoasthenoteratozoospermia (44.8% of cases). Asthenozoospermia was the most common abnormality (90.9% of cases), followed by oligozoospermia (87.4% of cases), teratozoospermia (66.9% of cases), necrozoospermia (55.6% of cases), and azoospermia (10.4% of cases). This study highlights that the cytological profile of the spermogram of this population in Butembo is dominated by associations of anomalies. Other tests such as bacteriological examinations and biochemical marker assays are necessary, in order to identify the causes of abnormalities and to provide appropriate therapies.

Semen quality among men attending urology services in the Dschang Health District, west Cameroon: A retrospective study on 379 cases. Int J Reprod Biomed 2020; 18:121-128. [PMID: 32259006 PMCID: PMC7097172 DOI: 10.18502/ijrm.v18i2.6419] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2019] [Revised: 07/11/2019] [Accepted: 08/14/2019] [Indexed: 01/20/2023] Open
Abstract
Background Infertility is a common condition affecting at least 15% of couples worldwide, and male factors are involved in about half of this prevalence rate. In Cameroon, about 20%-40% of couples are the victims. However, the sperm characteristics of infertile men are yet to be described in the health districts in Cameroon for better management of male infertility. Objective The present study was designed to assess the sperm profile and related sociodemographic factors of men attending the urology services at the Dschang Health District. Materials and Methods It consisted of a 10 yr retrospective study carried out in the Dschang Health District. The results of patients' semen analysis (SA) were computed using Epi Info software and expressed as qualitative and quantitative spermogram state as described by the clinician and sociodemographic features of those patients. Results Out of the 379 patients studied, 83.91% had abnormal spermogram. Patients older than 50 yr were the most affected when grouped into age categories. With regard to patient's profession, 52.51% had specified their profession and from that group, although farmers (9.31%) represented the lowest size category, they were the most affected with 94.74% having abnormal spermogram. Conclusion This study indicates that the sperm damage is the major cause of male infertility in the Dschang Health District. It also shows that farmers are the most affected category and it could be linked to the long-term exposure to pesticides. These results call for the assessment of the reproductive toxicity of locally used pesticides.

Abstract
Glutathione S-transferases are important detoxification enzymes involved in the metabolism of endogenous as well as exogenous compounds. Individuals differ in metabolic capacity due to inherited genetic variations. Due to the polymorphism exhibited by GSTT1 and GSTM1 that results in the complete loss of function, the present study was aimed towards the determination of the frequency distribution of GSTT1 and GSTM1 in agricultural workers in Punjab, India. The study aimed to investigate their contribution in susceptibility to increased disease risk. A total of 513 subjects were included in this study, out of which 250 were agriculture workers and 263 were non-exposed occupationally. GSTT1 and GSTM1 null-genotype distribution was analyzed through multiplex-PCR method. Complete gene deletion in either of the genes was strongly associated with an increased risk (OR = 1.8; 95% CI = 1.3-2.6; p < 0.0008) of DNA/cytogenetic damage, cancer, infertility, and many other serious health effects. Therefore, homozygous deletion in GSTT1 or GSTM1 could play a modulatory role in health of workers with long-term exposure to pesticides.

Abstract
A limited number of studies have reported an association between male factor infertility (MFI) and dental health status (DHS). The aim of the present study was to assess the association between DHS and MFI through a systematic review of indexed literature. To address the focused question-"Is there a relationship between DHS and MFI?"-indexed databases were searched up to March 2016 using various key words "infertility," "periodontal disease," "periodontitis," "dental infection," "caries," and "odontogenic infection." Letters to the editor, case reports, commentaries, historic reviews, and experimental studies were excluded. In total seven studies were included in the present systematic review and processed for data extraction. All the studies reported a positive association between MFI and DHS. The number of study participants ranged between 18 and 360 individuals. Results from six studies showed a positive association between chronic periodontitis and MFI. Three studies reported a positive relationship between MFI and odontogenic infections associated to necrotic pulp, chronic apical osteitis, and radicular cysts. One study reported a relationship between caries index and MFI. From the literature reviewed, there seems to be a positive association between MFI and DHS; however, further longitudinal studies and randomized control trials assessing confounders are needed to establish real correlation. Dentists and general practitioners should be aware that oral diseases can influence the systemic health. Andrological examination should include comprehensive oral evaluation, and physicians detecting oral diseases should refer the patient to a dentist for further evaluation.
