Characteristics of prolactin-modulated LH induction of LH/hCG receptors. Transient inhibition of receptor induction following prolactin exposure
LH luteinizing hormone
2009/2/23
The temporal relationship between exposure to prolactin (PRL) and luteinizing hormone (LH) induction of LH receptors was investigated in hypophysectomized adult male rats. Testicular homogenate me...
The prolactin response of males to a standard MVO2 treadmill test
prolactin response males standard MVO2 treadmill test
2009/2/23
The concentration of serum prolactin in response to a standard MVO2 treadmill stress test to self-perceived exhaustion was investigated in 19 normal healthy males. The prolactin concentration remain...
Effect of gonadotropin-releasing hormone on prolactin levels in males unrelated to stress or behavioral changes
gonadotropin-releasing hormone prolactin levels males

Hormone levels, physiologic parameters, electroencephalographic (EEG) activity, and changes in subjective feelings recorded using a nonverbal instrumental device were assessed following the double-b...
Increased plasma and pituitary prolactin concentrations in adult male rats with selective elevation of FSH levels may be explained by reduced testosterone and increased estradiol production
Increased plasma pituitary prolactin concentrations adult male rats

The roles of testosterone and estradiol in regulating prolactin concentrations were studied in acutely castrated adult male rats receiving subcutaneous Silastic implants of the sex steroids. Testost...
Changes in serum levels of LH, FSH, prolactin, testosterone, and cortisol associated with season and mating in male pygmy goats
serum levels LH FSH prolactin testosterone cortisol season male pygmy goats

Pulsatile secretion of gonadotropins and prolactin in male marathon runners. Relation to the endogenous opiate system
gonadotropin prolactin endurancetraining marathon runners pulsatile secretion opiates
2009/2/20
We tested the hypothesis that sustained, strenuous physical training alters the neuroendocrine regulation of pulsatile gonadotropin and/or prolactin secretion in men. Blood was sampled at 20-minute ...
