,
December 2017 in “Systems Biology in Reproductive Medicine” This meta-analysis found that lower serum SHBG levels are associated with an increased risk of PCOS, and improving SHBG levels through treatment may reduce PCOS complications.
71 citations
,
June 2006 in “Human Reproduction” This study found that in young Taiwanese women with PCOS, low sex hormone-binding globulin levels were associated with low HDL cholesterol levels, independent of insulin resistance and obesity.
58 citations
,
November 2020 in “International Journal of Molecular Sciences” This review discusses the relationship between SHBG, NAFLD, and PCOS and reports no new clinical results; the authors highlight low hepatic SHBG production as potentially significant in PCOS pathogenesis.
53 citations
,
January 1985 in “Acta obstetricia et gynecologica Scandinavica” This study found that an 8-month treatment with a low-dose oral contraceptive significantly reduced testosterone levels and hair growth in women with polycystic ovary syndrome and hirsutism, with minimal side effects.
40 citations
,
March 1982 in “British Journal of Dermatology” This study found that women experiencing diffuse hair loss had significantly lower levels of plasma sex-hormone binding globulin compared to controls, while their testosterone levels remained normal.
39 citations
,
September 2012 in “Human Reproduction” This study found that specific SHBG gene variants, rs727428 and rs6259, were associated with PCOS in Mediterranean women, although the associations were relatively weak and do not indicate a causative role.
36 citations
,
April 2011 in “Journal of The American Academy of Dermatology” People with hair loss have higher risk of high blood sugar and diabetes, and lower levels of a specific hormone.
29 citations
,
January 2006 in “Clinical chemistry and laboratory medicine” This study found that male liver cirrhosis patients have higher estradiol levels and lower dehydroepiandrosterone sulfate, leading to hormonal imbalances favoring estradiol, but without changing sex hormone-binding globulin's binding properties.
29 citations
,
September 1983 in “British Journal of Dermatology” This study found that men with androgenetic alopecia had significantly lower levels of sex hormone binding globulin and higher salivary testosterone compared to controls, while plasma testosterone levels did not differ.
24 citations
,
November 2015 in “Annals of Nutrition and Metabolism” This study found that specific SHBG gene variants and haplotypes are associated with polycystic ovary syndrome, suggesting that SHBG may be a candidate gene for the condition.
15 citations
,
August 2010 in “Fertility and sterility” This study found that girls with polycystic ovary syndrome and longer SHBG and AR gene repeats experienced greater improvements in lipid and androgen levels after one year of metformin treatment.
13 citations
,
December 2020 in “BMJ Open Diabetes Research & Care” This study found that while intensive lifestyle interventions were associated with favorable changes in SHBG levels due to reduced adiposity, these changes did not consistently predict diabetes risk reduction.
13 citations
,
September 1986 in “Archives of Dermatology” This study found that women with female pattern baldness often had a higher ratio of 3 alpha,17 beta-androstanediol glucuronide to sex hormone-binding globulin and lower serum sex hormone-binding globulin, possibly indicating minimal androgen excess.
4 citations
,
August 2024 in “PLoS ONE” In this study, researchers reported that both progestin-only injectable contraceptives, DMPA-IM and NET-EN, significantly decreased serum testosterone and SHBG levels among HIV-negative women in South Africa, yet this did not explain prior findings of no reduction in risky sexual behavior or sexual function.
1 citations
,
January 2023 in “Journal of Obstetrics and Gynaecology” This study found that pregnant Egyptian women with PCOS and recurrent miscarriages showed elevated DHEA levels and shortened cervical length, which may negatively impact pregnancy outcomes.
August 2024 in “Journal of Biomedical Research & Environmental Sciences” This review consolidates existing research showing that lower SHBG levels are significantly associated with adverse reproductive, metabolic, and cardiovascular outcomes, suggesting its importance as a marker in managing various health conditions.
March 2024 in “BMC women's health” This study found that free testosterone levels were 29% higher with the levonorgestrel implant than with the DMPA injection, which may impact sexual function, mood, and side effects like acne.
September 1989 in “PubMed” This study found no significant differences in sex-hormone binding globulin and androgen serum levels between women with stage II androgenetic alopecia and controls, suggesting that genetically-determined androgen sensitivity might play a major role in the condition.
August 1987 in “European journal of endocrinology” This study found no correlation between plasma androgen levels and androgenetic alopecia in women, suggesting that increased androgen action may not be reflected in these parameters.
November 1986 in “PubMed” In this study, women with male pattern alopecia had significantly lower serum sex hormone binding globulin levels compared to healthy controls, while testosterone levels remained similar.
35 citations
,
