  • Collagen metabolism markers as a reflection of bone and soft tissue turnover during the menstrual cycle and oral contraceptive use
  • 2000

    • Two different groups of women, 23 healthy young adults and 13 women with chronic posterior pelvic pain, were studied before and during use of oral contraceptives (OC). Collagen metabolism markers-here, the amino-terminal propeptide of type I procollagen, the carboxy-terminal telopeptide of type I collagen, and the amino-terminal of procollagen type III-as well as hormones and other endocrine factors indicating the balance between androgen expression/anabolism and catabolism of the subjects (testosterone, sex-hormone binding globulin, and insulin-like growth factor I were measured. Type I procollagen, the carboxy-terminal telopeptide of type I collagen, and the amino-terminal of procollagen type III were all significantly decreased during OC use. These findings implicate OC use-induced changes in collagen type I and III turnover. A shift in the anabolic/catabolic balance was also recorded indicating a less anabolic situation during OC use.

  • Liver metabolism during treatment with estradiol and progesterone
  • 1993
  • Ingår i: Gynecological Endocrinology. - 0951-3590. ; 7:2, s. 111-114
  • Tidskriftsartikel (refereegranskat)abstract
    • Serum concentrations of sex hormone-binding globulin (SHBG), corticosteroid binding globulin (CBG), ceruloplasmin, lipoprotein A and liver enzymes were measured in 30 postmenopausal women treated with 2 mg micronized 17 beta-estradiol daily and micronized progesterone orally in doses of 50, 100 and 200 mg daily, as progestogen supplementation. The treatment lasted for 4 months. The serum levels of SHBG and CBG increased during treatment and a weak association between progesterone dosage and CBG was observed. Levels of lipoprotein A and liver enzymes did not change. It is concluded that micronized natural progesterone is an attractive means of progesterone supplementation in postmenopausal hormone replacement therapy without any liver-related side-effects.

  • Effects of combined estrogen/testosterone therapy on bone and body composition in oophorectomized women.
  • 2005
  • Ingår i: Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology. - 0951-3590. ; 20:3, s. 155-60

    • OBJECTIVE: To evaluate the effect of adding testosterone undecanoate 40 mg daily to estrogen therapy on bone markers, bone mineral density and body composition in oophorectomized women. METHODS: Fifty women, 45-60 years old, who had undergone a hysterectomy and bilateral salpingo-oophorectomy for benign disorders, were randomly assigned to oral treatment with testosterone undecanoate 40 mg plus estradiol valerate 2 mg daily or placebo plus estradiol valerate 2 mg daily. Twenty-four weeks later, cross-over was performed to the other treatment regimen. Forty-four women completed the study. Their serum concentrations of insulin-like growth factor (IGF)-I, IGF binding protein (IGFBP)-3, osteocalcin, carboxyterminal telopeptide aminoterminal (ICTP), of type I collagen propeptide of type I procollagen (PICP) and interleukin (IL)-1 receptor antagonist were measured at baseline and after 24 weeks of both treatments, as were also their body mass index (BMI) and blood pressure. Bone mineral density of the total body, spine and hip and total body fat, total lean body mass, trunk fat and trunk lean mass were determined by dual-energy X-ray absorptiometry measurements at baseline and after 24 weeks of both regimens. RESULTS: During treatment, the addition of testosterone counteracted the decrease in IGF-I and PICP seen with estrogen therapy alone. Osteocalcin and ICTP were significantly reduced to the same extent by both therapies. No change ocurred in the IL-1 receptor antagonist. A significant increase was seen in total lean body mass with the estrogen/testosterone regimen, but the total fat mass, trunk lean or fat mass remained unchanged after 24 weeks of both treatments. No effect was detected on total, hip or spinal bone mineral density after treatment with estrogen alone or estrogen/testosterone. Likewise, BMI and blood pressure were unaffected. CONCLUSIONS: The addition of testosterone to oral estrogen might have positive effects on bone as suggested by the fact that it counteracted the decline in IGF-I and PICP levels. An anabolic effect on muscle was reflected by an increase in the total lean body mass. No adverse effects were noted on BMI, fat distribution or blood pressure during the 6-month treatment with oral testosterone undecanoate.

  • Cognitive function in association with sex hormones in postmenopausal women
  • 2013
  • Ingår i: Gynecological Endocrinology. - 0951-3590. ; 29:1, s. 59-62
  • Tidskriftsartikel (refereegranskat)abstract
    • Several studies have suggested gender differences in cognitive function, but data on the association between sex hormones and cognitive function are contradictory. The aim of our randomized double-blind study was to explore the possible relations between cognitive function and serum levels of sex hormones, oxytocin and insulin-like growth factor-I (IGF-I) in postmenopausal women. Two-hundred healthy postmenopausal women were randomly assigned to receive estrogen, testosterone or placebo treatment for 1 month. The associations of spatial ability, verbal fluency and verbal memory with serum levels of estradiol, testosterone, estradiol/testosterone ratio, androstanediol, oxytocin and IGF-I were analyzed. Spatial ability showed a negative correlation with serum estradiol, estradiol/testosterone ratio, oxytocin levels and a positive association with androstanediol levels. Verbal fluency displayed a negative relationship with serum levels of testosterone, IGF-I and a positive with estradiol/testosterone ratio. Verbal memory displayed a positive correlation to androstanediol. Data suggest that not only absolute levels of sex hormones but also the balance between estrogen and testosterone and their metabolites may be important for cognitive function in women. © 2013 Informa UK, Ltd.

  • Reproductive hormones and stress urinary incontinence in pregnancy
  • 2001
  • Ingår i: Acta Obstetricia et Gynecologica Scandinavica. - John Wiley & Sons. - 0001-6349. ; 80:12, s. 1125-1130
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The cause of transient stress urinary incontinence during pregnancy remains uncertain. Anatomical change, such as a pressure effect of the enlarged uterus, changes in renal function, and alterations in bladder and urethral function have been proposed. There is little information about the role of reproductive hormones in stress urinary incontinence with onset during pregnancy.METHODS: In a prospective, longitudinal, observational cohort study 200 consecutive women attending in early pregnancy were observed by repeated measurements of stress urinary incontinence, its possible determinants as well as serum concentrations of progesterone, estradiol and relaxin.RESULTS: The prevalence rate of stress urinary incontinence increased to a stable level of about 25% from mid-pregnancy and increased with parity. A higher serum relaxin value early in pregnancy was correlated to a lower prevalence rate of stress urinary incontinence with onset during pregnancy, also when the influence of potentially important factors was taken into account in a multivariate analysis. No significant difference was shown regarding serum concentrations of estrogen or progesterone, maternal age, weight gain, time since last delivery or smoking, although this can be due to a small sample size.CONCLUSION: The reproductive hormone relaxin might have a role in maintaining urinary continence during pregnancy. A mechanism is uncertain.
