We analyzed the relation between reproductive history and risk of uterine fibroids using data from a case-control study. Cases were 621 women with histologically confirmed diagnosis of uterine fibroids. Controls were 1,051 non-hysterectomized patients. Compared with nulliparae, parous women had a relative risk (RR) of fibroids of 0.5 [95% confidence interval (CI) = 0.4-0.6], and the risk declined with number of births. The risk of fibroids also decreased with number of induced abortions (RR = 0.8 and 0.6 for women reporting one or two or more abortions, respectively). A total of 24 cases (3.9%) and 19 controls (1.8%) reported a history of infertility (RR = 2.0; 95% CI = 1.1-3.7).

Introduction Premature ejaculation (PE) is the most frequent sexual complaint. Aim To investigate prevalence of PE and its associated conditions. Methods We analyzed information gathered from men attending a free andrologic consultation in 186 Italian medical centers, in the setting of a project focused on andrologic prevention. Main Outcome Measures Risk factors for PE. Results Five hundred sixty-nine men suffered from lifelong PE; 1,855 had previously normal ejaculation; and 234 had PE not specified. Men with PE were younger than those without, but after adjusting for concomitant erectile dysfunction the risk of PE significantly decreased with aging. Men more educated, or who had experienced a divorce had a slightly increased risk. Also, lifestyle and occupational status affected the risk of PE. Concerning medical history, a decreased risk of PE emerged in men with treated diabetes, and no association was found with hypertension, cardiopathy, hypercholesterolemia, and peripheral or central neuropathy. Conclusions The results of the analysis of a large dataset show that subjects with PE who are seeking treatment either have experienced stress-related problems or have a physical condition predisposing to this dysfunction (genital anomalies, prostate inflammation).

Alcohol consumption is widespread in the Western world. Some studies have suggested a negative association between alcohol intake and semen quality although others have not confirmed this. MEDLINE and Embase were searched using 'alcohol intake' OR 'alcohol consumption' OR 'alcohol drinking' OR 'lifestyle' combined with 'semen quality' OR 'sperm quality' OR 'sperm volume' OR 'sperm concentration' OR 'sperm motility' for full-length observational articles, published in English. Reference lists of retrieved articles were searched for other pertinent studies. Main outcome measures were sperm parameters, if provided as means (standard deviation or standard error) or as medians (interquartile range). Fifteen cross-sectional studies were included, with 16,395 men enrolled. Main results showed that alcohol intake has a detrimental effect on semen volume (pooled estimate for no/low alcohol consumption 0.25 ml, 95% CI, 0.07 to 0.42) and normal morphology (1.87%, 95% CI, 0.86 to 2.88%). The difference was more marked when comparing occasional versus daily consumers, rather than never versus occasional, suggesting a moderate consumption did not adversely affect semen parameters. Hence, studies evaluating the effect of changes on semen parameters on the reproductive outcomes are needed in advance of providing recommendations regarding alcohol intake other than the advice to avoid heavy alcohol drinking.

Our results suggest that this specific mixture of probiotics (LS01 and BR03 strains) may induce beneficial effects for clinical and immunologic alterations in adult AD. This combination could be considered as adjuvant therapy for the treatment of AD in adult patients.

BackgroundSemen quality, a predictor of male fertility, has been suggested declining worldwide. Among other life style factors, male coffee/caffeine consumption was hypothesized to influence semen parameters, but also sperm DNA integrity. To summarize available evidence, we performed a systematic review of observational studies on the relation between coffee/caffeine intake and parameters of male fertility including sperm ploidy, sperm DNA integrity, semen quality and time to pregnancy.MethodsA systematic literature search was performed up to November 2016 (MEDLINE and EMBASE). We included all observational papers that reported the relation between male coffee/caffeine intake and reproductive outcomes: 1. semen parameters, 2. sperm DNA characteristics, 3. fecundability. All pertinent reports were retrieved and the relative reference lists were systematically searched in order to identify any potential additional studies that could be included.ResultsWe retrieved 28 papers reporting observational information on coffee/caffeine intake and reproductive outcomes. Overall, they included 19,967 men. 1. Semen parameters did not seem affected by caffeine intake, at least caffeine from coffee, tea and cocoa drinks, in most studies. Conversely, other contributions suggested a negative effect of cola-containing beverages and caffeine-containing soft drinks on semen volume, count and concentration. 2. As regards sperm DNA defects, caffeine intake seemed associated with aneuploidy and DNA breaks, but not with other markers of DNA damage. 3. Finally, male coffee drinking was associated to prolonged time to pregnancy in some, but not all, studies.ConclusionsThe literature suggests that caffeine intake, possibly through sperm DNA damage, may negatively affect male reproductive function. Evidence from epidemiological studies on semen parameters and fertility is however inconsistent and inconclusive. Well-designed studies with predefined criteria for semen analysis, subject selection, and life style habits definition, are essential to reach a consistent evidence on the effect of caffeine on semen parameters and male fertility.

Weight gain and body mass index (BMI) increase are central issues in patients living with HIV who need to minimize the risk of metabolic disease. Information collected through the SCOLTA cohort revealed significant 1-year BMI increase in patients treated with dolutegravir (P = .004), raltegravir (P = .0004), elvitegravir (P = .004), darunavir (P = .0006), and rilpivirine (P = .029). BMI gain correlated with low baseline BMI (P = .002) and older age (P = .0007) in Centers for Disease Control and Prevention stages A/B, with lower BMI (P = .005) and CD4+ T-cell count (P = .007) at enrollment in stage C.
