Insights
Hysterectomy with ovarian conservation (HYX) in postmenopausal women was linked to improved bone density and strength. This suggests the uterus may play a previously unrecognized role in bone metabolism regulation.
Area of Science:
- Endocrinology
- Orthopedics
- Gynecology
Background:
- The impact of hysterectomy with ovarian conservation (HYX) on bone metabolism and density in postmenopausal women is not fully understood.
- Previous research has not extensively explored the uterus's role in bone health regulation.
Purpose of the Study:
- To investigate the effects of hysterectomy with ovarian conservation (HYX) on bone metabolism and density in healthy postmenopausal women.
- To assess potential correlations between HYX and bone turnover biomarkers and bone mineral density (BMD).
Main Methods:
- Evaluated 176 healthy Caucasian postmenopausal women (aged 48-59) comparing those with and without a history of HYX.
- Measured bone properties (hip, spine, radius, tibia, calcaneus) using various assessment modalities.
- Assessed bone turnover via serum biomarkers: bone-specific alkaline phosphatase (BAP), osteocalcin (OC), and tartrate-resistant acid phosphatase (TRAP) 5b.
Main Results:
- Women with HYX exhibited significantly lower osteocalcin (OC) levels (P=0.017) and marginally lower TRAP 5b (P=0.051).
- Higher bone mineral density (BMD) was observed in the femoral neck (P=0.037) and lumbar spine (P=0.001) in women with HYX.
- Increased cortical BMD and bone strength index (I(polar)) of the tibia were noted in women with HYX (P=0.055 to P<0.005).
Conclusions:
- Hysterectomy with ovarian conservation (HYX) is associated with improved bone mineral density and strength in postmenopausal women.
- These findings suggest a potential, previously unrecognized role of the uterus in regulating bone metabolism.
Abstract:
We evaluated whether hysterectomy with ovarian conservation (HYX) has an effect on bone metabolism and density in 176 healthy Caucasian postmenopausal women aged 48-59 years. Bone properties of the hip, spine, radius, tibia, and calcaneus were measured using different bone assessment modalities. In addition, bone turnover was assessed using serum bone-specific alkaline phosphatase (BAP), osteocalcin (OC), and tartrate-resistant acid phosphatase (TRAP) 5b as biomarkers. Our results showed that women having HYX had a significantly lower level of OC ( P = 0.017) and a marginally lower level of TRAP 5b ( P = 0.051) and higher bone mineral density (BMD) of the femoral neck ( P = 0.037) and lumbar spine ( P= 0.001) than women with no history of HYX. In addition, the cortical BMD and bone strength index (I(polar)) of the tibia also showed higher values at different sections in women having HYX than women with no history of HYX ( P = 0.055 to P< 0.005). These results suggest that the uterus may have a role in regulating bone metabolism that has not been detected previously.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
Oogenesis
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
