The influence of a diet containing soy protein on the hormonal status and regulation of the menstrual cycle was examined in six premenopausal women with regular ovulatory cycles. Soy protein (60 g containing 45 mg isoflavones) given daily for 1 mo significantly (P < 0.01) increased follicular phase length and/or delayed menstruation. Midcycle surges of luteinizing hormone and follicle-stimulating hormone were significantly suppressed during dietary intervention with soy protein. Plasma… 
Effects of an isoflavone-free soy diet on ovarian hormones in premenopausal women.
TLDR
It is suggested that at least under the conditions of this study, a soy diet with low levels of isoflavones and low energy intake from protein can reduce circulating ovarian steroids without altering gonadotropins and may have implications for breast cancer prevention.
Effects of soy intake on sex hormone metabolism in premenopausal women.
TLDR
Soy consumption had no significant effect on the menstrual cycle, serum sex hormones, or urinary estrogen metabolite ratio in premenopausal OC or non-OC users.
Soy isoflavones exert modest hormonal effects in premenopausal women.
TLDR
Data suggest that effects on plasma hormones and the menstrual cycle are not likely to be the primary mechanisms by which isoflavones may prevent cancer in premenopausal women.
Effect of soymilk consumption on serum estrogen concentrations in premenopausal Japanese women.
TLDR
Much larger studies will be required to confirm the ability of soy products to reduce serum estrogen levels, as well as to determine the effect of soy consumption on serumosterone levels in premenopausal women by use of a dietary intervention approach.

TLDR
It is suggested that soy isoflavone consumption may exert cancer-preventive effects by decreasing estrogen synthesis and altering metabolism away from genotoxic metabolites toward inactive metabolites.

TLDR
Soy and isoflavone consumption does not seem to affect the endometrium in premenopausal women, although there have been weak estrogenic effects reported in the breast and the magnitude of the effects is quite small and of uncertain significance.

Soybean consumption is associated with reduced rates of breast, prostate, and colon cancer, which is possibly related to the presence of isoflavones that are weakly estrogenic and anticarcinogenic.
Fourth International Symposium on the Role of Soy in Preventing and Treating Chronic Disease Hormonal Effects of Soy in Premenopausal Women and Men 1
Over the past few years, there has been increasing interest in the possible hormonal effects of soy and soy isoflavone consumption in both women and men. Soy consumption has been suggested to exert
Decreased ovarian hormones during a soya diet: implications for breast cancer prevention.
TLDR
It is suggested that at least under the conditions of this study, soya-induced reductions of circulating ovarian steroids are not mediated by gonadotropins, and may explain decreased ovarian hormone levels and decreased risk of breast cancer in populations consuming soya diets and have implications for reducing breast cancer risk by dietary intervention.
Effects of soy foods on ovarian function in premenopausal women
It has been proposed that the high intake of soy foods among Asians may partly explain their lower rates of breast cancer, perhaps by lowering endogenous oestrogen levels, although this has been

Nonsteroidal estrogens of dietary origin: possible roles in hormone-dependent disease.
TLDR
It is confirmed here that phytoestrogens which are abundant in dietary soya protein are converted by human gastrointestinal flora to this weak estrogen, and that some subjects are unable to either produce or excrete equol despite the challenge of a diet containing soya.
Dietary effects on breast-cancer risk in Singapore
TLDR
The finding that soya products may protect against breast cancer in younger women is of interest since these foods are rich in phyto-oestrogens.
Increases in steroid binding globulins induced by tamoxifen in patients with carcinoma of the breast.
TLDR
It is inferred that tamoxifen has a direct oestrogen-like action on the liver which results in increased production of CBG and SHBG, and therapy for carcinoma of the breast appeared to be least effective in those patients in whom the drug caused the highest increase in the concentration ofCBG.

TLDR
Both hypotheses suggest that the risk of breast cancer could be reduced by delaying the onset of regular ovulatory menstrual cycles and by minimizing the therapeutic use of oestrogens, and possibly of progestagens, in postmenopausal women.
Effects of tamoxifen treatment on plasma lipids and lipoprotein lipid composition.
TLDR
Changes in lipoprotein composition together with the fall in LDL cholesterol and increase in sex hormone-binding globulin indicate that tamoxifen acts as an estrogen agonist on the liver.
Long-term adjuvant therapy with tamoxifen: effects on sex hormone binding globulin and antithrombin III.
TLDR
The estrogen-like rise in sex hormone binding globulin produced by adjuvant tamoxifen therapy could be advantageous for maintaining the antiestrogenic action of the drug.
Hypocholesterolemic effect of substituting soybean protein for animal protein in the diet of healthy young women.
TLDR
In this study, the mean plasma cholesterol level was found to be significantly lower on the plant protein diet, compared with the conventional diet.
Effects of Infant Nutrition on Cholesterol Synthesis Rates
TLDR
The type of infant nutrition and dietary cholesterol are major factors influencing cholesterol fractional synthesis rates in infancy and it is shown for the first time that dietary phytoestrogens are absorbed and excreted by the infant fed soy protein-based formula.
Endocrine effects of adjuvant chemotherapy and long-term tamoxifen administration on node-positive patients with breast cancer.
TLDR
It is suggested that the optimal antitumor activity of TAM will be achieved in a low estrogen environment with continuous high levels of the drug in the serum, and patients undergoing long-term TAM therapy be monitored for complete ovarian failure and drug compliance.
Effects of tamoxifen therapy on lipid and lipoprotein levels in postmenopausal patients with node-negative breast cancer.
TLDR
It is concluded that during the first 12 months of treatment, tamoxifen exerts a favorable effect on the lipid profile in postmenopausal women with early stage breast cancer.
