To assess the effect of treatment with the androgen testosterone undecanoate on seminal variables and frequency of pregnancy in subfertile men with idiopathic oligoasthenozoospermia.

Study design

Descriptive Case Series.

Place & Duration of study

Department of Obstetrics & Gynaecology, Bahawal Victoria Hospital & Civil Hospital Bahawalpur, from December 2015 to December 2018.


Men, aged 18-50 years, who visited the outpatient department with the complaint of infertility were enrolled in this study. They were given testosterone undecanoate 40mg t.i.d for 3 months and followed up for another 3 months without treatment. Seminal analysis was done after 3 days of abstinence, before and after treatment as well as at the end of a 3-month treatment-free follow up period.


A total of 1800 patients were included. Asthenozoospermia was the most common abnormality, found in 76.1% (n=1370) of the sample. The baseline mean sperm concentration was 16.65 +7.14x106/ml and the mean percentage of progressively motile sperm was 17.21+ 13.52%. These parameters increased to 54.28 + 20.11x106/ml and 35.07+ 16.39% at the end of 3-month follow up period, respectively. Pregnancies were achieved in 469 (26.05%) female partners of male patients during the study period.


Testosterone undecanoate has tangible positive effects on seminal parameters leading to conceptions among subfertile couples.
