does it cause estrogen or no

Check the section I posted this inonly MILF titty milk works sorry
True ;(Even looksmaxing section is shit now
you are part of the problem.Even looksmaxing section is shit now
So is that yes or noyou are part of the problem.
Why post shitty questions which you could easily google? This is the first article I found by searching "milk estrogen study"

"Since steroid hormones pass the blood-milk barrier thus there is no doubt about the existing of them in milk, as the presence of steroid hormones especially progesterone content in milk is used as a diagnostic toll of pregnancy. Very early studies showed that the main estrogen in cow’s milk is the biologically inactive 17β-estradiol, which followed by estrone and 17β-oestradiol (86). The presence of 17β-oestradiol, estrone- and estriol-sulphate in human breast cyst fluid has already been demonstrated (87, 88). The source of the estrogens synthesis and secretion is the big challenge for endocrinologists, which there are considerable attempts to show that whether or not it is mammary glands that synthesize and secret the bovine milk estrogens or some other tissues and glands and/or it is combination of them. Janwski and co-workers showed that oestrone, oestrone sulphate and 17β-oestradiol are not secreted by bovine mammary gland, however their preliminary in vitro studies indicated the synthesis of 17-β-oestradiol by mammary tissues (89).
The main source of animal-derived estrogens (60–70%) in the human diet is milk and dairy products (83). Recently, free and conjugated forms of estrogens including 17β-oestradiol, estrone and estriol (Fig. 1), have been detected and quantified (90). They found that estrone is the major estrogens with 69% participation between the detected estrogens and for the estrone, the conjugated form is the predominant (90%). The distribution of estrogens especially 17β-oestradiol in fat or non-fat parts of milk still is controversial, as Abeyawardene and co-workers reported that 52% of 17β-oestradiol content in milk is distributed in fat phase, in contrast Lopez and his team demonstrated that there is no difference in 17β-oestradiol concentrations between milk samples which processed as composite whole milk or composite defatted milk (91, 92). Hartmann and co-workers conducted a market basket survey and measured the steroid concentration in milk and milk products using GS/MS method (93). They found a maximum concentration of total estrone (sum of free and conjugated forms) in butter with 1.47 ng/g, which followed by 0.26, 0.17, 0.16, and 0.13 ng/g (or ng/ml) in cream, Gouda cheese, yoghurt, and milk, respectively. The level of 17β-oestradiol, which has been determined in that particular survey, was less than 0.02–0.03 ng/g in all milk and milk products samples (Table 2). Qin and his research team by using HPLC method could determine the free concentration of estriol in Holestain cows, milk as 27 ± 12 pg/ml (94). Indeed, they could determine both free and conjugated forms of estrogens in cows, milk (Table 3). We also analysed the occurrence of estrogens in processed and raw milks from pregnant and non-pregnant cows, using liquid chromatography-tandem mass spectrometry (95). The cumulative concentration of free and enzymatically deconjugated estrogens in the third trimester (1639 ng/L) was >27 times higher than that in milk of cows in their first trimester of pregnancy (60 ng/L) (Table 4). It is well known that the high concentrations of estrogens appear at oestrus period of non-pregnant cows and levels increase markedly after pregnancy (96, 97)."

Tldryou are part of the problem.
