I am also posting some of the reviews of the products I have reviewed in my blog, in case they are useful for you.
I am currently conducting my first online sex hormone tests to help a friend with his first test. The test is being carried out by a company called Endocrine Consultants (EC), who has been in the business since 1995, with a reputation for delivering excellent results. They are run by Dr. Charles M. F. Trencher. Dr. Trencher has written two books, The Male Contraceptive, and a book on male hormones. Both books are written by women and are based on medical evidence. He is not promoting the products and is in no way an expert in the topic. He's just one of many doctors who treat men. I use the products with my clients and have not found a single negative experience, despite many many years of using them. There is a small but vocal group of people who try to prevent men from getting them and I don't condone that. I understand the pain of having to choose. It's a natural process and I respect that.
Trencher's books have also been used in the past by anti-abortion activists, as in: "The abortion pill has created a lot of controversy with anti-abortion groups that use the product." In 2010, Trencher was involved in an undercover investigation by the Washington Examiner to expose the use of an anti-abortion drug by the "pro-choice" abortion rights group Operation Rescue.
