- 在瘤学瘤学.
- 儿科内分泌学 儿科内分泌学
背景情况:
- 使用未成熟的丸组织 (ITT) 保存生育能力对于子生育计划至关重要.
- 恢复生育能力的成功取决于冷保存的ITT中的精子细胞数量.
- 关于恶性瘤类型如何影响前青春期男孩的丸生殖细胞种群的数据有限.
研究的目的:
- 调查和比较ITT中的精子和塞尔托利细胞种群,来自患有血液和非血液恶性瘤的青春期前男孩.
- 评估癌症类型对用于生育保存的ITT细胞组成的影响.
主要方法:
- 对从ITT样品中取出的精管进行了体病理学和免疫化学分析.
- 从14名接受生育保护的青春期前男孩获得了样本,分为血液 (N=7) 和非血液 (N=7) 癌症组.
- 每个管状截面的精子和塞尔托利细胞数量被量化.
主要成果:
- 每个管状截面的精子数量在血液学组为3.43±2.92,在非血液学组为1.71±1.81.

Infertility in Males
260
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

Spermatogenesis
102.4K
Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male...

Disorders of the Male Reproductive System
393
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....

Bone Marrow Sampling and Transplants
324
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...
