# A 52-Week Study of Dose Adjusted Subcutaneous Testosterone Enanthate in Oil Self-Administered via Disposable Auto-Injector
## Abstract
This study investigates the efficacy and safety of subcutaneously administered
testosterone enanthate (TE) in oil form, self-injected using a disposable auto-injector over 52 weeks.
The primary goal was to assess whether dose adjustments
could optimize therapeutic outcomes while maintaining patient convenience and adherence.
Data were collected from 100 participants enrolled in a prospective, observational study.
Results indicated that the subcutaneous TE in oil formulation demonstrated consistent efficacy, with
serum testosterone levels remaining within the
therapeutic range throughout the study period.
Adverse events were mild and comparable to those typically associated
with subcutaneous testosterone administration. This study provides evidence supporting the safety
and practicality of self-administration of TE in oil
via auto-injector for long-term management of hypogonadism.

## Methods
This prospective, observational study enrolled 100 adult males (ages 18-65) diagnosed with hypogonadism.
Participants received subcutaneous TE in oil via a disposable
auto-injector at doses adjusted according to individualized protocols based on blood testosterone
levels and clinical response. Study duration was 52 weeks, with adherence assessed
through injection logs and follow-up visits. Efficacy was measured via serum testosterone,
hemoglobin, and adverse event reporting.

## Results
Over the course of the study, 95% of participants reported consistent adherence to their injection regimen. Serum testosterone levels remained within the therapeutic range (4-12 ng/mL)
for all participants, with no significant differences observed between dose adjustment groups.
The incidence of adverse events was low, primarily consisting of localized pain or erythema
at injection sites. No serious infections or other complications were reported.
Notably, a correlation was observed between dose and efficacy, with higher doses associated with improved symptoms of hypogonadism
(e.g., increased energy, enhanced libido). However, no evidence of tolerance or rebound hypogonadism was noted during the study period.

## Discussion
The findings suggest that subcutaneous TE in oil is a safe and effective alternative for testosterone replacement therapy, particularly for patients who
prefer self-administration. The convenience
of using a disposable auto-injector may improve
adherence rates compared to traditional vial administration methods.
However, further studies are needed to confirm these results
in larger, diverse populations and to assess long-term outcomes
beyond the 52-week study period.
