The IGSF1 gene inhibits the activin A pathway which decreases the rate of FSHB expression. IGSF1 gene deficiency leads to over-secretion of pituitary FSH causing an early and rapid increase in the testicular sertoli cell mass (i.e. macroorchidism) in children and adults with FSH-secreting pituitary adenomas.

It is the most common testicular tumor in children under three, [2] and is also known as infantile embryonal carcinoma. This age group has a very good prognosis. In contrast to the pure form typical of infants, adult endodermal sinus tumors are often found in combination with other kinds of germ cell tumor, particularly teratoma and embryonal ...
Testicular cancer is cancer that develops in the testicles, a part of the male reproductive system. [2] Symptoms may include a lump in the testicle or swelling or pain in the scrotum. [2] Treatment may result in infertility. [2] Risk factors include an undescended testis, family history of the disease, and previous history of testicular cancer. [5]
It was sign of testicular rhabdomyosarcoma, a childhood form of a soft tissue cancer. He is cancer free. Boy diagnosed with testicular cancer at 16 recalls early symptom: ‘I thought it was normal’
In the testis pure embryonal carcinoma is also uncommon, and accounts for approximately ten percent of testicular germ cell tumours. However, it is present as a component of almost ninety percent of mixed nonseminomatous germ cell tumours. The average age at diagnosis is 31 years, and typically presents as a testicular lump which may be painful.
Testicular teratomas present as a palpable mass in the testis; mediastinal teratomas often cause compression of the lungs or the airways and may present with chest pain and/or respiratory symptoms. Some teratomas contain yolk sac elements, which secrete alpha-fetoprotein. Its detection may help to confirm the diagnosis and is often used as a ...
The most common type of testicular cancer occurring in undescended testes is seminoma. [5] It is usually treatable if caught early, so urologists often recommend that boys who had orchiopexy as infants be taught testicular self-examination, to recognize testicular masses and seek early medical care for them. Cancer developing in an intra ...
Spermatoceles can be discovered as incidental scrotal masses found on physical examination by a physician or by self-inspection of the scrotum and testicles. [7] The various types of diagnosis for spermatocele types include hydrocele, varicocele, hernia, simple epididymal cyst, and neoplasm. [8]
