Abstract A hormone is classically considered to be a bioactive molecule that is transported via the circulation from its site of synthesis to its site of action elsewhere in the body, where it exerts its effects on specific target cells through receptor-mediated mechanisms.

Testicular Descent Related to Growth Hormone Treatment
Journal of Pediatric Endocrinology and Metabolism, 2003An 8.7 year-old boy with cryptorchidism and growth hormone (GH) deficiency due to septooptic dysplasia presented testicular descent related to the commencement of hGH treatment. This case suggests a role for GH in testicular descent.

Anterior Pituitary Hormonal Regulation of Testicular Gonadotropin-Releasing Hormone Receptors*
Endocrinology, 1984Testicular GnRH receptors are increased 2-fold 1 day after hypophysectomy and remain elevated for up to 6 days. Consequently, the present study was undertaken to determine which pituitary hormone(s) regulated testicular GnRH receptors. Adult male rats were hypophysectomized and injected sc every 8 h for 2 days with LH, FSH, GH, PRL, estradiol ...

Testicular Control of Follicle-Stimulating Hormone Secretion
1976Publisher Summary This chapter provides an overview of the testicular control of follicle-stimulating hormone (FSH) secretion. Castration is followed by an increase in circulating levels of FSH than of luteinizing hormone (LH). This suggests the possibility that the mechanisms of gonadotropin secretion either have different thresholds to steroid ...

THYROID HORMONES: THEIR ROLE IN TESTICULAR STEROIDOGENESIS
Archives of Andrology, 2003Thyroid hormones are important for growth and development of many tissues. Altered thyroid hormone status causes testicular abnormalities. For instance, juvenile hypothyroidism/neonatal transient hypothyroidism induces macroorchidism, increases testicular cell number (Sertoli, Leydig, and germ cells) and daily sperm production.

Treatment of testicular hypofunction with gonadotrophic hormones
International Urology and Nephrology, 1978The paper reports on the response to gonadotrophic hormone treatment in cases of male infertility. The report includes 119 cases treated between 1971 and 1975. The evaluation of the results of gonadotrophic hormone treatment led to the following conclusions.

Hormonal Regulation of Testicular Function
1980The testis has two functions: spermatogenesis and androgen production, mainly testosterone. These two functions are localized in different compartments in the testis: the first in the seminiferous tubules, the second in the Leydig cells situated in the interstitial tissue.
