Ok thanks Dr. Saya. To be clear while the article makes a case study reference to a woman after 6 hours of contact they also reference several studies that illustrated transference occurring at 12 hours. See below for excerpts:
" In one study (UMD-98-037), males applied 100 mg of AndroGel to the upper arms, shoulders and abdomen. They were asked to have 15 min of intensive abdomen-to-abdomen skin contact with their spouses per day for a period of 7 days. The time between application of the gel and skin contact varied from 2 to 12 h between different groups. One group of men was asked to wear a shirt covering the exposed areas during abdominal contact. The mean 24 h plasma testosterone level in the exposed women doubled after 1 day and even quadrupled after 1 week of skin contact. Mean testosterone levels in women were lower when the interval between application and skin contact was longer; however, even 12 h after application, considerable transfer of testosterone appeared to take place, indicating that transfer and uptake of transferred testosterone may take place long after application of the gel. Wearing a shirt prevented a detectable increase in testosterone levels in women. Taking a shower 1 h after application of the gel also prevented significant transfer (UMD-99-023) without significantly affecting the mean 24 h testosterone level in treated males. This shows that most applied testosterone is absorbed through the skin shortly after application. A similar study (AUX-TG-206) was conducted using Testim 100 mg applied to the abdomen with 15 min intensive skin contact 1–12 h after application. The mean 24 h testosterone level in the female partners increased up to 12 times from the baseline level. Even in the group who had skin contact 12 h after application, the mean 24 h testosterone levels in women were 8-fold over the baseline level. Wearing a shirt did not completely prevent transfer of testosterone. Applying Testim to the shoulders (AUX-TG-209) appeared to lower transfer potential significantly. Showering 1–6 h after application of the gel lowered the 24 h mean testosterone levels in treated men by 25–30% (AUX-TG-207).From these studies, it can be concluded that both gels have the potential to raise testosterone levels in women after skin contact with treated men even hours after application. Wearing a shirt covering the application sites or taking a shower after application appears to minimize the risk of testosterone transfer."
