Background:
The sex cord-stromal tumors are relative rare, comprising 5-8% of all ovarian neoplasms.
Methods:
The study androgen tumors and a description of three cases: Leydig tumor, steroid cell (NOS) tumor and Sertoli-Leydig tumor.
Results:
Twelve patients were menopausal and one patient of reproductive age. In all cases, regardless of the histological variety, women presented symptoms of hyperandrogenism and virilization. All had increased values of total testosterone. In all cases surgical treatment was performed, with favorable clinical and biochemical evolution.
Conclusions:
Sex cord stromal tumors of the ovary are rare, and can be characterized by virilization for most patients. The majority of the tumors are benign, with few cases having low-grade malignancy. The suspicion and correct evaluation of these women will lead to an early diagnosis and improve their quality of life.

Regulation of Hormone Secretion

Hormones Secreted by the Stomach
Each of these hormones secreted by different enteroendocrine cells plays a unique role in digestion. Here are a few examples:
Pancreatic Juice and Secretion
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...
Tubular Reabsorption and Secretion
Tubular reabsorption is a selective process that starts when the filtrate enters the proximal tubules. It involves substances traveling through the transcellular route (through the tubule cell and peritubular...
Reabsorption and Secretion in the PCT
Transport mechanisms involving sodium ions (Na+) contribute significantly to solute reabsorption. These mechanisms include symport and antiport processes.
