Read about two studies (cited below), both of which discovered that men with higher serum levels of lignan have reduced rates of prostate cancer. A third study (cited below) states that flaxseed-derived enterolignans may hinder rapid cancer cell production.
There are two main types of androgens in men: testosterone and dihydrotestosterone (DHT).
DHT is a more potent and potentially more dangerous hormone than testosterone. DHT is critical in the early stages of life for development of the male sex organs. However, later in life, its accumulation can cause prostate cancer, balding in men, and cardiovascular inflammation.
The enzyme 5-alpha-reductase synthesizes DHT in the prostate and hair follicles. DHT gets stored in the prostate and in the hair follicles. Lignans can help prevent the metabolic errant conversion of testosterone into DHT by reducing the amount of 5a reductase enzyme in the body, effectively reducing DHT.
Over time, the lignans will reduce the amount of DHT in hair follicles and additional hair growth may be seen. The hair follicles are not dead, rather, they become dormant. Oftentimes baldness is a result of atrophy in the hair follicles as a result of DHT.
As lignans can aid in the reduction of DHT in the prostate, some men have reported reduced urination frequency and more urine flow when taking lignans. Several studies show a reduced rate of prostate cancer in men with higher amounts of lignan as measured from plasma levels.
Lignans and melatonin both block aromatase enzyme. Aromatase enzyme is responsible for converting testosterone into estrogen. Many body builders use lignans to block aromatase enzyme as a way of maintaining testosterone levels by preventing testosterone loss in the conversion.Studies
A case-control study conducted in Scotland found that higher serum enterolactone concentrations were associated with a lower risk of prostate cancer

Flaxseed SDG may have a therapeutic role in lupus nephritis. (Clark W. et al Lupus, 9(6): 429, 2000) Asian men have a much lower incidence of prostate cancer and possibly of benign prostatic hyperplasia (BPH) than Western counterparts. Vegetarian men have a lower incidence of prostate cancer than omnivorous males. Plant lignans give rise to the mammalian lignans, enterodiol and enterolactone; the richest source is linseed (flaxseed). In addition to their estrogenic activity, these plant compounds can interfere with steroid metabolism and bioavailability, and also inhibit enzymes, such as tyrosine kinase and topoisomerase, which are crucial to cellular proliferation and hence may contribute to lower incidences of prostate cancer.

A study published on the US government web site National Institute of Health stated that "Flaxseed-derived enterolactone is inversely associated with tumor cell proliferation in men with localized prostate cancer."

"In conclusion, flaxseed-derived enterolignans may hinder cancer cell proliferation via VEGF-associated pathways.”

writes, "I am 71 years old. The males in my family seem to be predisposed to prostate cancer and other prostate problems. I was diagnosed with BPH approximately 6 years ago, which elevates PSA. My attending physician had me try everything, including herbal remedies, but with little or no relief. A friend of mine mentioned Flaxseed Lignans and the results of my internet search led me to Lignans for Life. I purchased a bottle of Flaxseed Lignan capsules and after one bottle, I have nothing but the highest praise about this product; I would recommend it without reservations. It has changed my life....I've ordered 4 more bottles so I will not run low."Margo H.
writes, “My husband, Gordon, has had a lot of problems urinating & has been on saw palmetto for two years. I started him on flaxseed hull lignans a month ago. In questioning him this past week, I found out that he only gets up once a night now. When urinating, he does not have nearly the problems beginning, he goes much less often, and he passes a lot more urine with each trip. Thanks for a great product!"Important Note
