Who is Zestica™ Fertility suitable for?
Zestica™ Fertility has been designed specifically for couples trying to conceive.
What is different about Zestica™ Fertility compared to other lubricants?
Zestica™ Fertility uses Hyaluronic Acid, a material with a well-understood profile and widely used in IVF clinics and part of IVF medium. HA also has some unique qualities in sperm protection and has been shown to boost motility in low motile sperm.
There are many lubricants on the market and whilst most of them are fine to use at other times when you are trying to conceive it is very important that you use a lubricant such as Zestica™ Fertility which is specifically designed to assist the conception process. Zestica™ Fertility is pH and osmolality balanced to match the optimum conditions for sperm.
Many OTC lubricants are formulated to have a pH of around 4-5 to match the vaginal pH. However when trying to conceive it is important to remember that the pH of sperm is around 7.2 and a low pH will damage and kill sperm and therefore should be avoided. Similarly, any lubricant with a petroleum or mineral content should be avoided as well as lubricants with pleasure additives (tingle/ taste additives etc.) which may negatively impact sperm survival.
Osmolality (the concentration of particles dissolved in a fluid) is another important factor. The optimal range for sperm function is between 270 and 360 mOsm/kg and Zestica Fertility® is formulated to this range. Outside this range, commonly seen in other lubricants, the function of sperm falls off dramatically.
Can Zestica™ Fertility be used to collect sperm in a condom?
Zestica™ Fertility can be used to collect sperm in a sperm friendly condom. Zestica™ Fertility is compatible with both latex and polyurethane condoms.
How should I store Zestica™ Fertility?
Zestica™ Fertility should be kept at room temperature, 5-30°C. Do not place in extreme temperatures such as in a fridge or directly exposed to sunlight.
What are the ingredients in Zestica™ Fertility?
The ingredients in Zestica™ Fertility are:
- Sodium Hyaluronate (HA)
- Phosphate Buffered Saline (PBS)
PBS balances the pH of Zestica™ Fertility with that of the body. The normal vaginal pH is acidic, however the pH of sperm is around 7.2, so it would normally find the vagina a hostile environment. Zestica™ Fertility helps to temporarily raise the pH within the vagina during intercourse. It helps to provide a sperm-friendly environment and increases the chance of conception. Zestica™ Fertility is also specially formulated to the optimal osmolality for sperm, 270-360 mOsm/kg; outside this range sperm perform very poorly.
Is the applicator recyclable?
The recyclable symbol (with a “4” in the middle) on the applicator shows that the applicator is made of a Low density polyethylene (LDPE). LDPE is a soft, flexible plastic. It is typically found in a variety of plastic bags including: bread bags, frozen food bags and plastic shopping bags. Though LDPE can be recycled, traditionally it has not been included in municipal recycling programs. However, more and more it is being added as an accepted plastic to Canada’s municipal recycling programs. There are no known health concerns connected to LDPE.
Is Zestica™ Fertility made with any animal products?
Zestica™ Fertility is not made with any animal product.
Sodium Hyaluronate (Hyaluronic Acid, HA) is the key ingredient of Zestica™ Fertility. HA is a non-toxic naturally occurring molecule (polysaccharide) that is found in the body in cervical tissue, skin and joints. It also helps surround the eggs (“oocytes”) around the time of ovulation where it plays an important role in fertilisation and embryo implantation.
It is often found as an ingredient in premium anti-ageing cosmetics and skin creams, is used in many popular injectable dermal fillers, used to combat wrinkles and folds, and has a well documented safety profile.
What are the benefits of Hyaluronic Acid?
Zestica™ Fertility uses a unique formulation with high and low molecular weight HA. HA has been used for many years as a key component in the “transfer medium” used by IVF clinics since several studies have indicated that HA plays a role in protection and selection of healthy sperm with fewer breaks in the DNA chains. DNA chain breaks in sperm are known to adversely affect the male contribution to the fertilised egg, affecting time to pregnancy, IVF fertilization and implantation rates.
Studies on Hyaluronic Acid have additionally shown an increased movement in otherwise poorly motile sperm!
The choice of HA for Zestica™ Fertility was based on these documented qualities thus helping select “healthy” sperm and maintain/improve their motility giving them an enhanced chance to reach the egg.
Are there questions about methylparaben?
Zestica™ Fertility is manufactured under aseptic conditions and uses low levels of preservatives (methylparaben and phenoxyethanol) to ensure that the product is made available to couples in optimum condition and remains so for the duration of its shelf life.
Used extensively for over 50 years, parabens are often present in small amounts in cosmetics and pharmaceuticals to prevent product contamination. The level of methylparaben in Zestica™ Fertility is very low at 0.1%. Parabens are, in fact, naturally occurring substances, and are found in blueberries, barley, strawberries, blackcurrants, peaches and carrots. Nature’s own preservative! Plus, parabens are rapidly absorbed by the body, rapidly metabolized, and rapidly excreted!
You may have heard reference to methylparaben being related to breast cancer. Many of these references stem from publications by Dabre claiming intact parabens found in breast cancer tissue. However, this initial and some related work were methodologically flawed and more comprehensive reports by the Danish Institute of Food & Veterinary Research in 2004 and the European Health & Consumer Protection Directorate (SCCP 0874/05) in 2005 both concluded that they found no relationship between parabens and breast cancer.
Indeed this work along with a publication by Danish researchers was considered by the European Health & Consumer Protection Directorate (SCCP 0874/05) and they found no relationship with the breast cancer and these studies.
Are there any concerns about Phenoxyethanol?
Phenoxyethanol is present at a concentration of 0.15%. In the EU, up to 1% is allowed for use in cosmetics and is considered “practically non-toxic”.
Phenoxyethanol can also be found in some natural products, like green tea.
