Male Birth Control Through Microencapsulation?

This article highlights a hormonal birth control formulation in development for men. Some methods of delivery for this drug will employ microcapsules:

“Researchers are now inching closer to discovering a contraceptive pill for men.

Men will soon have the options of a daily oral pill, a patch or gel to be applied to the skin, an injection given every three months or an implant placed under the skin every 12 months as birth control methods.

For the first time, safe, effective and reversible hormonal male contraceptives are expected in the market.

“The technology is there and we know how it would work. In the next few years, it will be in the market,” says Andrea Coviello, who is helping to test several male contraceptives at the Population Centre for Research in Reproduction at the University of Washington in Seattle.

Dr Coviello and her colleagues have found that a male contraceptive that releases testosterone over three months is potentially a safe and practical method of contraception.

The Seattle researchers have been testing a testosterone microcapsule that, they say, will be in the market in three to five year. [sic]”
