“…Comparing 92 ceramic oven operators with long exposure to high temperatures (37°C, 8 h/day) to 87 controls, it was found that the mean TTP was signi®cantly longer in the exposed group (3.3 vs. 1.3, p 0X05), although semen analysis showed no signi®cant differences, except in sperm velocity (Figa-Talamanca et al, 1992). The TTP for the last pregnancy was not compared between exposed and non-exposed workers (Agnew et al, 1991;Bonde, 1992). The sperm count, motile sperm count, sperm concentration, and the proportion of normalshaped spermatozoa fell within 4 to 6 weeks of the ®rst exposure to heat (31°C to 45°C, 5 h/day) in a subgroup of 10 welders, and increased 4 weeks after cessation of heat exposure in another subgroup of eight welders.…”

The relationship between male occupational heat exposure and the time required to achieve a pregnancy [TTP] was studied in a retrospective survey of 402 fertile couples. The TTP for t he subgroups 'exposure t o heat' (median = 4 .0 months; mean 11.8; SD = 13.3) and 'professional driver >3 h/day' (median = 4.5; mean = 14.4; SD = 28.5) was significantly longer (both p < 0.05) than for the controls (median = 2.8; mean = 7.8; SD = 13.3). Bakers and welders showed comparable results: only 14% of the bakers' partners became pregnant within 3 months (cf. 55% of controls, p < 0.05) and only 29% became pregnant within 6 months (cf. 74% of controls, p < 0.02). This study suggests that occupational exposure to heat is a 'weak' risk factor for male subfertility.

“…Exposure to heat, resulting in increased scrotal temperature, has been associated with decreased semen quality. 30,31 Hairdressers have been reported to have slightly lower fecundability (probability of conception) than controls, 32 and hairdressing involves exposure to numerous chemicals, some of which have been shown to cause reproductive toxicity in animal studies. 33 A fertility specialist should evaluate both husband and wife to try and pinpoint where the fertility problem(s) lies.…”

“…Didymitis causes decreased testicular volume and oligospermia [10]. Being exposed to heat, noise, and physical exercise causes testicular damage and finally terato and oligoasthenospermia [11]. Patients with an STI background have an obvious leukocytospermia, and sufficient primary treatment of STI can prevent delayed complications [12].…”

Introduction: Premature ejaculation (PE) is one of the most common disorders in sexual intercourses among men and may occur for any man in any period of his life. PE results in some mental disorders such as anxiety, depression and marital disaffection and can have psychological impacts. The present study is aimed to investigate the effect of the abstinence time on the semen analysis parameters among men. Methods: The present cross-sectional study was conducted on a statistical population including 100 male patients referring to the urology clinic in Ali-Ibn-Abitaleb Hospital. Once included in the study, these individuals are divided into three groups with short-term abstinence (less than 2 days), mid-term abstinence (2-9 days), and long-term abstinence (more than 9 days). The patients, depending on the group to which they belonged, were asked to deliver their semen at the specified time to the laboratory in less than an hour. The obtained data were statistically analyzed in SPSS-22 software. Findings: The results of Pearson correlation and Spearman tests indicated a direct positive relationship between the abstinence time and the total number of sperms in the seminal fluid, concentration of the sperms in the seminal fluid, volume of the seminal fluid, sperm DNA fragmentation, reactive oxygen species in the seminal fluid, and pH of the seminal fluid.accordingly, the longer the abstinence time, the more the occurrence of these disorders. Also, the correlation test results showed that the abstinence time had an inverse relationship with motility and morphology of the sperms in the seminal fluid; accordingly, with elongation of the abstinence time, the motility (mobility) and morphology of the sperms in the seminal fluid were reduced. Conclusion: The researchers in the present work concluded the presence of a relationship between the abstinence time and the quality of the sperm parameters. Results of the present study showed that the abstinence time is significantly associated with the total sperm count, sperm concentration seminal fluid volume and pH.
