Dexter, they say its progesterone but for all we know, they could be using some kind of progestin with similar effects. Too much to assume or speculate but thats just my 2 pennies.

Exactly what I'm saying / thinking.
Progesterone doesn't mean "PROGESTERONE".

Kindof like vitamin & mineral supplements. When it says calcium, it could be lots of different types of calcium.

These links are about PROGESTINS (Progesterone Type)

Types of Progestin Found in Combination Birth Control Pills

8 types of Progestin
1. Norethindrone
2. Norethindrone Acetate
3. Ethynodiol Diacetate
4. Levonorgestrel
5. Norgestrel
6. Desogestrel
7. Norgestimate
8. Drospirenone

No use of "PROGESTERONE" though.

I think there is opportunity to look at Progesterone as a Pheromone.

Because:
1) it is a hormone
2) it is excreted from the human body by breath
3) curiosity of it being an ingredient listed by boyth GYNEX/Spellbound and Suregasm (Suregasm doesn't claim and pheromones though)
4) Seems to be gender specific polarized as a female hormone

Progeterone is a pretty good marker of ovulation. Also known as "In Heat" when woman's body temp will rise by 1-2 degrees F, signalling ovulation. HMM. What would a good signal be externally, a pheromone.

My son who is 4 has an uncanny ability to ask women who don't look pregnant, if they are pregnant. So far he is always right. I wonder if he has a good nose for progesterone.

The fact that saliva levels of progesterone are representative of blood serum levels means that women's breath will reveal if they are ovulating/"In Heat" or not.

Levels higher than ovulation would reveal if a woman is more than 8 weeks pregnant, this is the point in time where the placenta kicks out Progesterone is large amounts. Up until full term pregnancy, where the placenta kicks out ~250mg/day.

Also, the fact that it is related to pregnenolone, allopregnanolone and dehydroepiandrosterone (DHEA) line it up for pheromone activity in my book.

Quote:Progesteron in the Nervous system
Progesterone, like pregnenolone and dehydroepiandrosterone, belongs to the group of neurosteroids. It can be synthesized within the central nervous system and also serves as a precursor to another major neurosteroid, allopregnanolone.

Neurosteroids affect synaptic functioning, are neuroprotective, and affect myelination.[36] They are investigated for their potential to improve memory and cognitive ability. Progesterone affects regulation of apoptotic genes.

Its effect as a neurosteroid works predominantly through the GSK-3 beta pathway, as an inhibitor. (Other GSK-3 beta inhibitors include bipolar mood stabilizers, lithium and valproic acid.)

------------
Progesterone modulates the activity of CatSper (cation channels of sperm) voltage-gated Ca2+ channels. Since eggs release progesterone, sperm may use progesterone as a homing signal to swim toward eggs (chemotaxis).

So it may also be a pheromone of type for egg/sperm comunication (marco polo type).
