Aligning with the continuous evolution of conceptualization, the fluidity of the robust measurement model was indispensable, stemming from a formula that identified a pool of reproductive age women in irrational situations, discrepant behavior, \u201cKAP-Gap\u201d and unmet need for contraception. Extant fertility literature suggests the possibility of some reproductive age women classified as having unmet need but genuinely have \u201cno unmet\u201d need. This study proffers that exposed women whose husbands have a virility issue attendant to genetic, health, social, and lifestyle factors may obliviously forgo birth control methods on the perception of reduced pregnancy risk. Upon incorporating husbands\u2019 virility loss, this study generated a modified \u201cRevised\u201d algorithm and utilized 2014 Kenya demographic and health survey data to select 8,710 reproductive age women who met fertility criteria. Using Stata \u00ae the modified \u201cRevised\u201d algorithm estimated unmet need for contraception at 16.4 percent, lower than national estimates by 1.1 percentage points, implying 6.6 percent overestimation. The \u201cmodified\u201d estimates were highest among adolescents, rural dwellers, and residents of Northeastern region but decreased with increasing education and household wealth. This study has generated a modified \u201cRevised\u201d algorithm, confirmed overestimation of \u201cunmet need\u201d for contraception, incorporated overlooked husband\u2019s virility loss, and proved reclassification of women from \u201cunmet need\u201d to \u201cno unmet need.\u201d These results, therefore, endorse incorporation of virility loss as a reason exuded by exposed reproductive age women for abstaining from birth control methods.<\/jats:p>","DOI":"10.1371\/journal.pone.0357392","type":"journal-article","created":{"date-parts":[[2026,8,31]],"date-time":"2026-08-31T17:28:10Z","timestamp":1788197290000},"page":"e0357392","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Incorporating husband\u2019s influence in estimating unmet need for contraception using modified revised algorithm"],"prefix":"10.1371","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-5867-7118","authenticated-orcid":true,"given":"Gerald Mbuthia","family":"Mahuro","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Murungaru","family":"Kimani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew Kyalo","family":"Mutuku","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"key":"pone.0357392.ref001","first-page":"93","volume-title":"Revising Unmet Need for Family Planning","author":"SEK Bradley","year":"2012"},{"issue":"2","key":"pone.0357392.ref002","doi-asserted-by":"crossref","first-page":"123","DOI":"10.1111\/j.1728-4465.2014.00381.x","article-title":"Understanding unmet need: history, theory, and measurement","volume":"45","author":"SEK Bradley","year":"2014","journal-title":"Stud Fam Plann"},{"issue":"2","key":"pone.0357392.ref003","doi-asserted-by":"crossref","first-page":"105","DOI":"10.1111\/j.1728-4465.2014.00380.x","article-title":"Unmet need for contraception: issues and challenges","volume":"45","author":"J Cleland","year":"2014","journal-title":"Stud Fam Plann"},{"issue":"2","key":"pone.0357392.ref004","doi-asserted-by":"crossref","first-page":"247","DOI":"10.1111\/j.1728-4465.2014.00387.x","article-title":"The impact of family planning programs on unmet need and demand for contraception","volume":"45","author":"J Bongaarts","year":"2014","journal-title":"Stud Fam Plann"},{"issue":"2","key":"pone.0357392.ref005","doi-asserted-by":"crossref","first-page":"227","DOI":"10.1111\/j.1728-4465.2014.00386.x","article-title":"Unmet need and fertility decline: a comparative perspective on prospects in sub-Saharan Africa","volume":"45","author":"JB Casterline","year":"2014","journal-title":"Stud Fam Plann"},{"issue":"6","key":"pone.0357392.ref006","doi-asserted-by":"crossref","first-page":"129","DOI":"10.4054\/DemRes.2017.37.6","article-title":"The effect of contraception on fertility: Is sub-Saharan Africa different?","volume":"37","author":"J Bongaarts","year":"2017","journal-title":"Demogr Res"},{"key":"pone.0357392.ref007","doi-asserted-by":"crossref","first-page":"39","DOI":"10.1111\/j.1728-4457.2016.00164.x","article-title":"Africa\u2019s unique fertility transition","volume":"43","author":"J Bongaarts","year":"2017","journal-title":"Popul Dev Rev"},{"key":"pone.0357392.ref008","doi-asserted-by":"crossref","first-page":"237","DOI":"10.1111\/padr.12009","article-title":"The effect of fertility decline on economic growth in Africa: a macrosimulation model","volume":"43","author":"M Karra","year":"2017","journal-title":"Popul Dev Rev"},{"key":"pone.0357392.ref009","unstructured":"UNDESA.
