His~Seedis an Intimate Moisturizer designed for semen collection for diagnostic or assisted reproduction procedures. It has been formulated specifically to mimic the pH and osmolality of a human ejaculate. Scientific studies have shown that the better the stimulation and enjoyment undergone while producing a sperm sample the more motile sperm are produced. His~Seedwas developed to assist you in what can often be a stressful situation of having to produce a sample at a specific time. His~Seedhas been used by donors at sperm banks and met with approval from the technicians and directors processing the samples.
Directions for use:
Tear away the tab at the top of the tube, and dispense all of the tube contents into your hand.
Proceed with manual stimulation until a sample is produced into the provided container.
The reason for sperm damage from most products can be seen when data on product pH and osmolarity are compared as in the following table.
The optimum pH value for sperm migration and survival in the cervical mucus is between 7.0 and 8.5 (according to the World Health Organization manual for examination of human semen and sperm-cervical mucus interaction 4th edition 2000). Sperm are very sensitive to low (acidic) pH and, to a lesser extent, elevated (alkaline) pH. Below pH levels of 6.9, sperm die at a rate that increases with lowering pH.
Sperm are also sensitive to both high and low osmolarities (ion concentration in solution) because these can cause them to either shrink or swell beyond their “critical volume limits”. A physiologic osmolarity* around 360 mOsm/kg (that of semen) is best for sperm function.
