I would like to know if a man in his 50's could benefit from using progesterone cream and if so how much should he use? Thank you.

 Men and progesterone
by: Wray

Hi Terri Yes men can benefit from progesterone. The dose ranges from 20mg/day to 200mg/day. It's critical to the production of sperm, influences spermiogenesis, sperm capacitation/acrosome reaction and testosterone biosynthesis. Progesterone inhibits 5-alpha reductase, the enzyme which converts testosterone to dihydrotestosterone, a safer alternative to the drug finisteride.

 Convert units to fluid measure please
by: Max

Could you convert the amount of cream in a tube from grams to ml and/or the oz weight to fluid ounces (US) please? I don't have an analytical balance to measure out the dosage. I do however have common cooking measuring implements. Thanks.

 Convert units to fluid measure please
by: Wray

Hi Max. The specific gravity of the cream is 0.94, almost the same as water, so we regard 1g to be the same as 1ml. Cooking measuring implements are the easiest to use, certainly initially until you become used to the amount, 1tsp equals 5ml. The amount of cream to use is not critical, what is important are the symptoms. The more severe, the more cream is needed. Hope this helps. Take care, Wray

 MEN-Soy? natpro has Soy product?
by: Anonymous

Wray (or anybody), Im confused, you say in another place on the blog responding to "man Boobs" as other causes..." Foods containing phytosterols, particularly soy, have oestrogenic affects. Soy reduces the sperm count in men, avoid eating it!". Yet one of the ingredients in Natpro is soy? Please advise the difference. Thank You
