Testicular volume discrepancy is associated with decreased semen quality in infertile Japanese males with varicoceles
Purpose We retrospectively reviewed infertile Japanese males for testicular volume discrepancies (D) and semen parameters to evaluate whether left grade II–III varicoceles (V) cause testicular damage. Methods Seventy-seven patients who had idiopathic male infertility and 88 who had V without other c...

We retrospectively reviewed infertile Japanese males for testicular volume discrepancies (D) and semen parameters to evaluate whether left grade II–III varicoceles (V) cause testicular damage.
Methods
Seventy-seven patients who had idiopathic male infertility and 88 who had V without other causes of infertility were examined. We excluded cases of azoospermia. Testicular volume was measured using a punched-out orchidometer. D was defined as a size difference of at least 3 ml. The frequency of D was compared between the patients with and without V. The semen parameters were reviewed in association with D and V.
Results
The mean left and right testicular volumes were 19.4 and 20.1 ml, respectively (

We retrospectively reviewed infertile Japanese males for testicular volume discrepancies (D) and semen parameters to evaluate whether left grade II–III varicoceles (V) cause testicular damage.
Methods
Seventy-seven patients who had idiopathic male infertility and 88 who had V without other causes of infertility were examined. We excluded cases of azoospermia. Testicular volume was measured using a punched-out orchidometer. D was defined as a size difference of at least 3 ml. The frequency of D was compared between the patients with and without V. The semen parameters were reviewed in association with D and V.
Results
The mean left and right testicular volumes were 19.4 and 20.1 ml, respectively (
p
< 0.001). D with a smaller left testis was more common in V+ cases than in V− cases (26.1 vs. 13.0%,
p
= 0.0351). The sperm count and motility were also significantly lower (
p
= 0.0213 and
p
= 0.0217, respectively) in the D+ patients with a smaller left testicular volume.
Conclusions
In the patients with V, D was more common than in those without V. The semen parameters were worse if D was present in the patients with V. These results indicated that V could induce testicular atrophy and negatively affect semen quality. Therefore, the ipsilateral reduced testicular volume is considered to be a sign of persisting testicular damage by V.</description><identifier>ISSN: 1445-5781</identifier><identifier>EISSN: 1447-0578</identifier><identifier>DOI: 10.1007/s12522-011-0118-1</identifier><identifier>PMID: 29662361</identifier><language>eng</language><publisher>Japan: Springer Japan</publisher><subject>Atrophy ; Fertility ; Gynecology ; Infertility ; Male infertility ; Males ; Medicine ; Medicine & Public Health ; Original ; Original Article ; Reproductive health ; Reproductive Medicine ; Semen ; Semen parameter ; Sperm ; Sperm count ; Sperm motility ; Testes ; Urology ; Varicocele</subject><ispartof>Reproductive medicine and biology, 2012-07, Vol.11 (3), p.117-121</ispartof><rights>Japan Society for Reproductive Medicine 2012</rights><rights>The Japan Society for Reproductive Medicine</rights><rights>2012.
