Steroid hormones have the potential to regulate at the transcriptional level the expression of
a number of proteins involved in the control of uterine activity. Progesterone and estrogens …

Our understanding of the molecular events which occur in human myometrium, causing it to
change from a quiescent organ to one with powerful contractile activity that expels the fetus …

Placental production of corticotrophin releasing hormone determines the length of gestation.
Corticotrophin releasing hormone stimulates fetal adrenal production of …

The uterus of mammalian species plays the central role in providing the appropriate
environment for the establishment and maintenance of pregnancy. The coordinated actions …

Increased uterine contractility at term and preterm results from activation and then
stimulation of the myometrium. Activation can be provoked by mechanical stretch of the …

The mechanism of labor initiation in humans has not been completely elucidated.
Prostaglandins, estrogens, and corticotropin-releasing factor (CRF) have all been shown to …

In this chapter, the author briefly reviews current theories of the mechanism of steroid
hormone action. The distribution of estrogen (E) and progesterone (P) receptors in the …

Increased uterine contractility at term and preterm results from activation and then
stimulation of the myometrium. Activation can be provoked by mechanical stretch of the …

Much progress has been recorded in the study of the endocrinology of pregnancy and
parturition in mammalian species in the past two decades. Interestingly, the most completely …

Early on the uterus has often been considered to be just a target organ for ovarian steroids
and a repository for pregnancy. At present it is well known that it actively elaborates several …
