Role for endogenous estrogen in prepubertal Sertoli cell maturation.
Reducing prepubertal endogenous estrogens led to increased numbers of Sertoli cells and the associated increased testicular size and testicular sperm production capacity in boars. The increased number of Sertoli cells might be due to a longer time for proliferation; delayed differentiation of Sertoli cells during suppressed endogenous estrogens would be consistent with this hypothesized, prolon...
متن کاملA Rare Cause of Prepubertal Gynecomastia: Sertoli Cell Tumor
Prepubertal gynecomastia due to testis tumors is a very rare condition. Nearly 5% of the patients with testicular mass present with gynecomastia. Sertoli cell tumors are sporadic in 60% of the reported cases, while the remaining is a component of multiple neoplasia syndromes such as Peutz-Jeghers syndrome and Carney complex. We present a 4-year-old boy with gynecomastia due to Sertoli cell tumo...

15 صفحه اولSertoli cell tumors associated with feminizing syndrome and spermatic cord torsion in two cryptorchid dogs
The association of cryptorchidism, functional Sertoli cell tumors, and spermatic cord torsion has been rarely reported in the literature. Two dogs were admitted for bilateral skin alopecia and weight loss. Both animals were cryptorchid and displayed a pendulous preputial sheath, prostate hypertrophy, and increased levels of circulating oestrogen. Transabdominal palpation and ultrasonography rev...
متن کاملLate morfofunctional alterations of the Sertoli cell caused by doxorubicin administered to prepubertal rats
BACKGROUND Doxorubicin is a potent chemotherapeutic drug used against a variety of cancers. It acts through interaction with polymerases and topoisomerase II and free radical production. Doxorubicin activity is not specific to cancer cells and can also damage healthy cells, especially those undergoing rapid proliferation, such as spermatogonia. In previous studies our group showed that etoposid...
