Drug: Testosterone
Drug: Nestorone®
Phase 1

Study Type: Interventional

Primary Purpose: Prevention
Official Title: A Multicenter, Randomized, Double-Blind Comparator Trial of the Safety and Sperm and Gonadotropin Suppression Resulting From Combined Use of Nestorone® Gel (0, 8 or 12 mg NES) and Testosterone Gel (10 g) Compared With Testosterone Gel in Normal Men

Primary Outcome Measures:
  • To determine the number of men who have suppression of sperm production ≤1 million/mL when using a daily regimen of Nestorone® Gel (0, 8 or 12 mg) and Testosterone Gel applied transdermally. [ Time Frame: 24 Weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To determine the number of men who have suppression of sperm production ≤ 3 million/mL or azoospermia when using a daily regimen of Nestorone® Gel (0, 8 or 12 mg) and Testosterone Gel. [ Time Frame: 24 Weeks ] [ Designated as safety issue: Yes ]
  • To determine the level of suppression of gonadotropins caused by transdermal usage of Testosterone Gel and 0, 8, or 12 mg Nestorone® Gel and to correlate the level of gonadotropin suppression with sperm suppression. [ Time Frame: 24 Weeks ] [ Designated as safety issue: Yes ]
  • To evaluate the impact on sperm morphology and motility in men who are not azoospermic. [ Time Frame: 24 Weeks ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Placebo Comparator: Testosterone Gel 10 g and Nestorone® 0 mg per day
Two individual packets of Testosterone Gel, each with 5 g of gel applied to each arm delivering a total of 100 mg of Testosterone on the skin. Nestorone® Gel will be delivered by a pump configured to deliver 4 mL of gel containing 0 mg of Nestorone® by pressing two times with the 2 mL dispenser head.
Drug: Testosterone
Two individual packets of T Gel, each with 5 g of gel applied to each arm delivering a total of 100 mg of T on the skin daily.
Drug: Nestorone®
Nestorone® Gel will be delivered by a pump configured to deliver 4 mL of gel containing 0 mg of Nestorone® by pressing two times with the 2 mL dispenser head.
Experimental: Testosterone Gel 10 g and Nestorone® 8 mg per day
Two individual packets of Testosterone Gel, each with 5 g of gel applied to each arm delivering a total of 100 mg of Testosterone on the skin. Nestorone® Gel will be delivered by a pump configured to deliver a metered volume of Nestorone® Gel containing 8 mg of Nestorone®. For 8 mg Nestorone® dose; Nestorone® Gel will be delivered in 4 mL volume (2 mg NES mL gel) by pressing two times with 2 mL dispenser head.
Drug: Testosterone
