The only lubricant clinically proven not to harm stallion sperm from the time of collection through 48 hours of cooled storage.
 

		Shown in independent studies to maintain better sperm function than other lubricants.
		Does not interfere with the ability of sperm to fertilize eggs or support embryo development.
		Based on the same patented, isotonic formula as the only lubricant indicated for use during human fertility procedures
		With the plant polysaccharide arabinogalactan, for antioxidant support.
		Does not cause mucosal irritation, as do leading lubricants.

Most lubricants damage sperm, as shown in numerous studies, and should be avoided for optimal sperm quality and outcomes:
 

Zero percent fertilization or embryo development after exposure to 10% Priority Care in a bovine in vitro fertilization model.

A motile sperm decline of over 30% within 3 hrs of contact to "non-spermicidal" veterinary lubricants in a fresh storage setting, as well as over the 48 hrs of routine cold storage.

Effect of Different Lubricants at 10% on Motility of Fresh Extended Stallion Sperm
(* means differ at p < 0.05 compared to control at same time point)

Effect of Different Lubricants at 10% on Motility of Cold-Stored Stallion Sperm
(* means differ at p < 0.05 compared to control at same time point)

Pre~Seed EQ is the ONLY lubricant to not decrease stallion sperm motility during both fresh & cold storage in prospective, blind studies.

Pre~Seed EQ does not interfere with the ability of sperm to fertilize eggs, or support subsequent embryo development, even after exposure to high concentrations of 50% (v/v).  (bovine in vitro fertilization model)

Pre~Seed EQ was developed by a DVM, PhD, Theriogenologist with over 15 years of federal funding in sperm physiology.
