Impact of long-term and short-term therapies on seminal parameters

Aim: The aim of this work was: i) to evaluate the prevalence of male partners of subfertile couples being treated with long/short term therapies for non andrological diseases; ii) to study their seminal profile for the possible effects of their treatments on spermatogenesis and/or epididymal maturation. Methods: The study group was made up of 723 subjects, aged between 25 and 47 years. Semen analysis was performed according to World Health Organization (WHO) guidelines (1999). The Superimposed Image Analysis System (SIAS), which is based on the computerized superimposition of spermatozoa images, was used to assess sperm motility parameters. Results: The prevalence of subjects taking pharmacological treatments was 22.7% (164/723). The prevalence was 3.7% (27/723) for the Short-Term Group and 18.9% (137/723) for the Long-Term Group. The subjects of each group were also subdivided into subgroups according to the treatments being received. Regarding the seminal profile, we did not observe a significant difference between the Long-Term, Short-Term or the Control Group. However, regarding the subgroups, we found a significant decrease in sperm number and progressive motility percentage in the subjects receiving treatment with antihypertensive drugs compared with the other subgroups and the Control Group. Conclusions: In the management of infertile couples, the potential negative impact on seminal parameters of any drugs being taken as Long-Term Therapy should be considered. The pathogenic mechanism needs to be clarified

Comparative study of seminal parameters between samples collected in 1992 and samples collected in 2010

Objective: The aim of this study was to conduct a comparative study of semen quality in two large populations; one evaluated in 1992 and another in 2010, in order to evaluate any possible decline in male fertility due, at least in part, to environmental factors. Material and Methods: A total of 701 subjects in 1992 (TOTAL group 1992) and a total of 626 subjects in 2010 (TOTAL group 2010) were enrolled in our Andrology Unit. Each group was subdivided into 3 subgroups: Subfertile, Pathology and Control. Standard semen analysis was performed using the Superimposed Image Analysis System, according to WHO guidelines 1987 (for TOTAL group 1992) and WHO guidelines 1999 (for TOTAL group 2010). Results: The mean values of sperm number (concentration/ml as well as the total ejaculate) and progressive motility were significantly higher in TOTAL group 2010 than TOTAL group 1992. Atypical forms in TOTAL group 1992 semen samples were significantly lower than TOTAL group 2010. The mean age of TOTAL Group 2010 was significantly higher compared with TOTAL Group 1992. In particular, the mean age gap was more evident in Subfertile subjects. Conclusions: In conclusion, environmental factors have not determined a significant decline in seminal parameters in the past 18 years

The impact of a diagnosis of couple subfertility on male sexual function

Aim: The aim was to study: a) the prevalence of sexual dysfunction in male partners of subfertile couples; b) the possible correlation between sexual dysfunction and seminal profile. Subjects and methods: Male partners (no.=171) of subfertile couples were studied, aged between 25 and 40 yr, attending the Andrology Unit of Sant'Andrea Hospital. All the subjects responded to a modified International Index of Erectile Function (IIEF) questionnaire, made up of 5 questions: 2 regarding erectile function, 1 concerning orgasmic function, 1 question on sexual desire, and 1 on satisfaction with intercourse. The questionnaire investigated both spontaneous sex for pleasure and sex intended to lead to pregnancy. The subjects underwent standard semen analysis, according to World Health Organization guidelines. Results: The data showed a disorder in sexual intercourse for reproductive purposes in 37 subjects (23.7%). Of these, only 14(8.9%) also had problems with sex for pleasure. On the other hand, there was no significant variation in the prevalence of sexual dysfunction related to seminal profile. Conclusions: A diagnosis of subfertility represents a stressful situation which can reduce the pleasure of sex, especially in intercourse intended for reproductive purposes; this disorder in sexual activity does not seem to be directly correlated with awareness of the severity of the semen alterations.

Seminal profile of subjects with testicular microlithiasis and testicular calcifications

Two hundred eighty-one male partners of infertile couples were studied to determine the prevalence of subjects with testicular microlithiasis (TM) or testicular calcifications JQ to define the seminal profile of this population and to initiate a longitudinal study to evaluate the significance of TM and TC as predictive markers of cancer. The prevalence found was 4.6% and 3.9%, respectively, which is sufficiently high to merit careful research attention, although TM and TC do not appear to be pathogenic factors of dyspermia.

Sexual dysfunction in diabetic women. prevalence and differences in type 1 and type 2 diabetes mellitus

Background: The aim of this work was to evaluate the impact of diabetes on female sexuality and to highlight any differences between sexuality in the context of type 1 and type 2 diabetes mellitus (DM). Methods: The subjects selected were 49 women with type 1 DM, 24 women with type 2 DM, and 45 healthy women as controls. Each participant was given the nine-item Female Sexual Function Index questionnaire to complete. The metabolic profile was evaluated by body mass index and glycosylated hemoglobin assay. Results: The prevalence of sexual dysfunction (total score <= 30) was significantly higher in the type 1 DM group (25/49, 51%; 95% confidence interval [CI] 18-31) than in the control group (4/45, 9%; 95% CI 3-5; P=0.00006); there were no significant variations in the type 2 DM group (4/24, 17%; 95% CI 3-4) versus the control group (P=0.630, not statistically significant). The mean total score was significantly lower in the type 1 DM group (30.2 +/- 6.9) versus the control group (36.5 +/- 4.9; P=0.0003), but there was no significant difference between the type 2 DM group and the control group (P=0.773). With regard to specific questionnaire items, the mean values for arousal, lubrication, dyspareunia, and orgasm were significantly lower only in the type 1 DM group versus the control group. The mean values for desire were reduced in type 1 and type 2 DM groups versus control group. Conclusion: Type 1 DM is associated with sexual dysfunction. This may be due to classic neurovascular complications or to the negative impact of the disease on psychosocial factors. Larger and ideally longitudinal studies are necessary to better understand the relationship between DM and sexual dysfunction

Human semen hyperviscosity: prevalence, pathogenesis and therapeutic aspects

The aims of this study were (a) to determine the prevalence of subjects with semen hyperviscosity (SHV) in a large population of male partners of subfertile couples; (b) to identify any correlation between SHV and infections or inflammation of the genital tract; (c) to assess the effects of therapeutic approaches for treating SHV; and (d) to assess sperm kinetic parameters after successful treatment of SHV. A retrospective study of 1 833 male partners of subfertile couples was conducted. Next, clinical, seminal, bacteriological and ultrasound studies involving 52 subjects suffering from SHV were performed, and the SHV was classified as being mild (length of thread > 2 cm and ≤ 4 cm), moderate (> 4 cm and ≤ 6 cm) or severe (> 6 cm). The prevalence of SHV was observed in 26.2% (480) of the subjects, with 13.2% suffering from mild, 6.6% from moderate and 6.4% from severe SHV. Treatment was completely successful in only 27 subjects (52.0%), primarily in those who had mild basal SHV with a positive semen culture. In these subjects, progressive motility percentage, straight line velocity and linearity were significantly higher than pre-treatment levels. SHV is often found in subjects with subfertility. Pathogenesis was strictly related to infective/ inflammatory factors in only 48.0% of cases; therefore, it is possible that biochemical, enzymatic or genetic factors have a role in this condition

Morphological sperm defects analyzed by light microscopy and transmission electron microscopy and their correlation with sperm motility

To compare sperm defects as assessed by light microscopy (LM) and transmission electron microscopy (TEM), and to correlate them with sperm motility. A cohort of 40 male partners of infertile couples was selected. Group 1 (n = 31) included subjects with motility >5 and <50%, group 2 (n = 9) included those with motility <5% and the control group consisted of 10 normospermic subjects. Semen analysis of morphological parameters was carried out by LM and TEM. A linear correlation between LM and TEM regarding head defects and excess residual cytoplasm (r = 0.87 and 0.90) was found, whereas there was a poor correlation between tail and midpiece anomalies (r = 0.46 and 0.21). No significant variations were detected by LM and TEM regarding sperm head defects and excess residual cytoplasm, whereas TEM showed a significantly greater percentage of tail and midpiece alterations compared with LM in groups 1 and 2, as well as controls (P < 0.05). The microtubular pattern '<9 + 2' represented the most frequent axonemal morphological alteration. TEM might represent an additional diagnostic tool in the presence of severe sperm hypomotility or absence of motility
