ABSTRACT
Background: Male factors contribute to almost 50% of infertile couples. Deleterious effects of tobacco smoking on male reproductive system are well known. Research studies report contradictory findings about the effect of tobacco chewing on male fertility. Aim and objectives: To study effect of tobacco chewing on seminal parameters in male partners of infertile couples. Material and Methods: Present study was conducted on 100 male partners of infertile couples (50 tobacco chewers and 50 non-chewers) in age group of 21-40 years in the semen analysis laboratory in department of Physiology of Government Medical College, Nagpur from October 2014 to March 2016. Seminal parameters like volume of ejaculate, sperm count, sperm motility and motile sperm count were measured and compared in both groups. Result: Tobacco chewers had significantly lower values of all the seminal parameters as compared to non-chewers. Significantly low values of all parameters were observed in severe tobacco chewers as compared to mild and moderate tobacco chewers. Conclusion: Tobacco chewing has adverse effect on seminal parameters of male partners of infertile couples thus proving its pronounced role in male infertility. Severity of this effect increases as duration of tobacco chewing is prolonged.
ABSTRACT
Objective To understand the characteristic of sexual behavior and their associated factors among male and female partners of men who have sex with men in Anhui province. Methods Cross-sectional studies were conducted among MSM in Hefei, Wuhu and Liuan in Anhui province. MSM were recruited through “snowball sampling” and “internet-based recruiting”, and eligible participant received an anonymous survey. Multivariate Logistic regression analysis model was used to identify risk factors associated with having sex with women in the last 6 months among MSM. Results Of the 1 200 MSM interviewed, 78.3% had anal sex with men, and 20.9% had vaginal intercourse with women, and 16.5% had sexual intercourse with both men and women in the past 6 months. Less MSM reported using condom every time with women (29.9%) in the past 6 months than with men (53.0%), and less reported using condom with women (52.2%) during the last sexual intercourse than with men(79.6%) (all P<0.05). The results of mutivariate Logistic regression analysis showed that MSM who were married(including currently married/cohabitating/divorced/widowed), lived more than 2 years in the surveyed city, and had commercial sex with men were more likely to have sex with women. Conclusions There was a high proportion of bisexual behavior and low rate of condom use among MSM. It should strengthen the sexual health education, risk perception education and behavioral intervention among MSM.
ABSTRACT
Aim: The aim of this study was to assess the knowledge and attitude of Nigerian men working in a tertiary institution toward infant feeding. Study Design: The study was cross sectional in design. Place and Duration of Study: The study was carried out in University of Ibadan, Ibadan, Nigeria between April 2013 and May 2013. Methodology: A pretested, self-administered questionnaire was used to obtain information on the socio-demographic characteristics, knowledge and attitude of 170 male staff of the University of Ibadan regarding infant feeding. Knowledge questions and attitude statements were scored and categorized as adequate or inadequate knowledge; positive and negative attitude. Data was analyzed using descriptive statistics and association between knowledge and attitude was analyzed using chi square test with level of significant set at P<0.05. Results: The mean age of the men was 41±9 years and a large proportion (87.6%) was married. The respondents were largely (75.9%) non-academic staff. About two-third (67.6%) of the men had poor infant feeding knowledge while three out of ten had good knowledge. Most of the men (76.5%) had negative attitude towards infant feeding while only two out of ten men had positive attitude. Three-quarters (75.7%) of men with poor infant feeding knowledge had negative attitude towards infant feeding while only 2 out of every 10 men with adequate infant feeding knowledge had positive attitude towards infant feeding. However, no significant association was reported between the knowledge and attitude of respondents toward infant feeding (P=.72). Conclusion: Poor infant feeding knowledge and negative attitude towards infant feeding exhibited by men is of great concern. Intervention should therefore be targeted towards improving the breastfeeding knowledge and attitude of male partners especially those working in tertiary academic institutions.
