There are also published cases where clinically significant elevations in testosterone concentration resulted from secondary transfer of testosterone gel from one person to another, including children 21,23,24, although controlled studies show this is likely a rare phenomenon . A publication in 2013 reported the same phenomenon in two adult patients prescribed testosterone gel for hypogonadism . Therefore, sampling time and age are important factors to consider when monitoring and interpreting serum testosterone in patients on TRT or GAHT. The influence of circadian rhythms on exogenous [testosterone online pharmacy](http://103.228.160.127:3100/demetravanderm) is unknown, but timing of dose and testosterone formulation influence measured testosterone serum concentrations. In the United States, testosterone formulations approved by the Food and Drug Administration (FDA) for testosterone replacement therapy (TRT) include intramuscular injections, transdermal patches, topical gels, implantable subcutaneous pellets, and buccal tablets , , . In general, guidelines aim for symptom improvement within the normal physiologic male range rather than supraphysiologic levels (Bhasin et al., Journal of Clinical Endocrinology & Metabolism, 2018). In transdermal therapy, timing matters differently. One reason lab conversations around TRT become confusing is that [buy testosterone online no prescription](https://gitea.lasallesaintdenis.com/abbie966999312) values are not independent of timing. This means women's TRT targets should not be "as high as possible while feeling good." The better standard is "the lowest effective exposure that stays within the female physiologic range and supports the specific symptom target under monitoring." Testosterone therapy in women has a much narrower evidence-based indication, with the strongest support in postmenopausal women with hypoactive sexual desire disorder (Davis et al., Journal of Sexual Medicine, 2019; Parish et al., Climacteric, 2021). Major consensus statements emphasize that there is no blood [buy testosterone online without prescription](https://jobs.khtp.com.my/employer/65361/sex-differences-in-the-association-between-testosterone-and-violent-behaviors/) cutoff that can diagnose a female androgen-deficiency syndrome the way clinicians diagnose male hypogonadism. Most testosterone serum measurements (39,878 of 40,979, 97.3 %) were performed in patients seen in the outpatient setting. The majority of testosterone serum measurements were for patients not prescribed any testosterone-containing medications at the time of the blood draw (Table 1; Fig. 1). We utilized EHR reporting tools (Epic Reporting Workbench) to retrieve all serum [buy testosterone online no prescription](http://xianyuhome.cn:11013/arturot515775) measurements from May 1, 2009 to March 31, 2022 along with pharmacy medical records for any testosterone preparations prescribed to patients who had serum [buy testosterone cream online](https://digitalafterlife.org/@lorenza2221687?page=about) measurements. Patient counseling and provider awareness of this potential cause of spuriously high testosterone serum concentrations is important. To prevent testosterone contamination, application of testosterone gel especially at the venipuncture site should be avoided. By alerting patients to the facts surrounding secondary transfer, healthcare professionals can instill caution in patients and help support them with practical strategies to reduce the risk. Prevention should begin with healthcare professionals educating patients on the practical steps to minimise transfer risk. After allowing for adequate drying time (read through the instructions of your testosterone gel), practical measures such as covering the applied area with clothing will minimise the risk of secondary transfer.9 The recommended drying time can be found on your patient leaflet that came with your testosterone gel. If testosterone rises above the female physiologic range, the risk of androgenic adverse effects increases and the treatment logic starts to break down (Parish et al., Climacteric, 2021; Parish and Kling, Menopause, 2023). In men, they’ve been linked to low testosterone, reduced sperm motility, and lower sperm count. Some of these chemicals mimic natural hormones like estrogen, while others disrupt metabolic pathways to suppress the production of testosterone. Recognising the signs of low testosterone is therefore important for timely intervention. We assessed the prevalence of abnormal T/E ratio in gel users and tested our hypothesis in 10 volunteers.

In most cases, the concentrations studied in vitro are unlikely to be reached in the human brain. It has been increasingly speculated that aside from more well-established side effects, testosterone may cause neurological damage. Due to declining testosterone levels from a variety of causes, testosterone replacement therapy (TRT) is increasingly utilized, while testosterone is also abused for aesthetic and performance-enhancing purposes. The risk of secondary exposure can be limited by hand-washing immediately after application of the gel, covering of the area with clothing, and limiting direct contact of skin with family members. This change in dose led to inadequate therapy, with a later increase in dose by another healthcare provider. Endocrinology documented that this very high value was likely a result of either gel contamination or a laboratory error. Approximately 3 months later, the patient reported being pleased with the masculinizing effects including growth of facial hair, deepening of the voice, and [forum.drustvogil-galad.si](http://forum.drustvogil-galad.si/index.php?topic=242726.0) enlargement of the clitoris. Men and women have different physiologic ranges, different evidence bases for treatment, and different monitoring goals. Supraphysiologic levels may increase adverse effects without improving the intended therapeutic outcome. Monitoring should also focus on clinical response and signs of androgen excess (Parish et al., Climacteric, 2021). Testosterone is a vital hormone that supports male characteristics and overall health. If you rub the gel in yourself, then make sure to wash your hands immediately afterwards.4 However, be sure to follow the steps discussed below to ensure you are doing everything you can to reduce the risk. The study also discovered that using a t-shirt could effectively reduce the risk of transfer by almost 50%.9 If post-application measures are not taken, adverse effects may occur.7 It’s important to remain cautious and take the necessary measures to reduce the risk. Again, if someone were to come into contact with the area of skin exposed to testosterone, then it may transfer onto another individual.4
