The expression of the recombinant proteins by transgenic animals represents an opportunity to achieve cost-effective, large-scale production of a wide variety of therapeutics. Among transgenic animal production systems, the transgenic mammary gland is the most advanced. However, the production of proteins in milk is limited by a relatively long interval from birth to first lactation encountered with domestic livestock, the discontinuous nature of the lactation cycle and the substantial time and material investments required to produce transgenic dairy animals. The semen of transgenic boar represents an alternative platform for the production of therapeutic proteins. The expression of such proteins in the male accessory glands, particularly in the seminal vesicle epithelium can be controlled by gene regulatory sequences specific to these tissues. In this review, we consider the possibility of using such regulatory sequences to drive the production of foreign proteins into the seminal fluids of transgenic animals. Application of this technology to pigs which can be ejaculated 2-3 times per week (200-300 ml per ejaculate), could lead to the annual production of several grams of recombinant protein.
