Oragene is the trade name for DNA Genotek's non-invasive DNA self-collection kit. Oragene allows the collection, stabilization and long-term storage of DNA from saliva at ambient temperature. Oragene first became available to the genetic research community in 2004. Oragene is available in a variety of formats for various markets.
A 2001 study involved performing daily saliva collection from healthy subjects and plotting these over the entire menstrual cycle. The researchers determined that salivary estradiol and progesterone curves corresponded to the daily profiles normally observed in blood, although of lesser amplitude. [ 33 ]
Artificial saliva for dry mouth in a mouthwash form. Artificial saliva or salivary substitutes refer to a synthetically produced liquid that mimics the natural secretion of saliva. It is designed as a symptomatic relief for xerostomia, a condition characterised by dryness in the mouth and is available over-the-counter.
A conception cap can assist to protect semen from the vaginal cavity and allow semen to pool against the cervical os. [8] [9] Around the time of ovulation, a conception cap or cervical cap is filled with semen and placed on a woman's cervical os for several hours to maximize the time the semen is available to fertilise a waiting egg.
A urine collection device or UCD is a device that allows the collection of urine for analysis (as in medical or forensic urinalysis) or for purposes of simple elimination (as in vehicles engaged in long voyages and not equipped with toilets, particularly aircraft and spacecraft). UCDs of the latter type are sometimes called piddle packs. [1]
Using a petri dish gel, the saliva sample is added and allowed to diffuse through the gel overnight. Visualization is accomplished by adding iodine to the gel which stains the starch in the gel blue. If saliva is present, then the alpha-amylase breaks down the starch, creating a clear coloured circle around where the sample was placed.

The paired submandibular glands (historically known as submaxillary glands) are major salivary glands located beneath the floor of the mouth.In adult humans, they each weigh about 15 grams and contribute some 60–67% of unstimulated saliva secretion; on stimulation their contribution decreases in proportion as parotid gland secretion rises to 50%.
