The Relationship Between Offspring Sex Ratio and Vasectomy Utilization

Abstract

Vasectomized fathers have a higher proportion of sons compared with non-vasectomized fathers, suggesting that offspring sex ratio is associated with a man's decision to undergo vasectomy. Further research is indicated to understand how offspring sex ratio impacts a man's contraceptive decisions.

Predictors of Male Sterilization among Eligible, Modern Method of Family Planning Users in India: Evidence from a Nationwide Survey

“…Concerning region, it emerged as an attribute of male sterilization among the selected sample population. This was in concordance with a study conducted in the USA by Lamberts et al (13) In the present study, those who were residing in southern India had 1.7 times higher odds of accepting male sterilization compared to those residing in the eastern part of the country. Eastern India comprises of states like Bihar, Jharkhand, Odisha and West Bengal.…”

“…Similarly, ethnicity emerged as an associate of male sterilization. Two different American studies by Lamberts et al (13) and Anderson et al (14) respectively found an association between race/ethnicity and male sterilization utilization which was in concordance with our findings. Those who belonged to lower socioeconomic status were more likely to undergo a vasectomy.…”

“…(12,13,14) Educational level of both the partners plays a crucial role in the decision of male sterilization as reported by a south Indian (10) and other studies around the world. (12,13,14,15,16) We did not find such an association between educational level and male sterilization. This may be because, we have only enrolled those who were using modern methods of family planning in our sample.…”

“…(9) As per existing literature, the attributes of acceptance of male sterilization were found to be the age of both husband and wife, their educational level, socioeconomic status, region/state they belong to, religious belief, ethnicity etc. (10)(11)(12)(13)(14)(15)(16)(17) Whereas barriers of NSV were found to be lack of information, religious prohibition, perceived negative impact of NSV on a man's health, concern regarding the safety of NSV, social stigma, uncertainty regarding the future desire for children etc. (18,19) Although the prevalence of using modern methods among currently married women of the reproductive age group in India slightly increased in NFHS-4 (51.2%) compared to NFHS-3 (48.5%), male sterilization declined from 1.0% in NFHS -3 to merely 0.3 % in NFHS-4.…”

Analysis of urban vs. rural vasectomy demographics: a multi-institutional, retrospective comparison

“…Similar to age, the correlation between number of children and vasectomy status has been described. One report revealed an average number of children of 2.5 at the time of vasectomy ( 8 ), while multiple studies have demonstrated increasing odds ratios for vasectomy with increasing number of children, although the effect seems to plateau after having 3 to 4 children ( 3 , 4 , 9 ).…”
