概括
大约一半的异常不育男性有异常的精子DNA碎片化 (SDF). 病理性SDF与老年和更高的胰岛素抵抗有关,这表明SDF测试对男性不孕症诊断具有临床相关性.

- 评估SDF测试在治疗异常男性不孕症中的临床相关性.
主要方法:
- 分析了3224名接受诊断工作的初级不育男性的数据.

- 排除已知不孕症原因 (遗传,荷尔蒙,解剖等) 的男性. ) 的情况.
- 使用了描述性统计和物流回归分析.
主要成果:
- 在792名被归类为异形不育的男性中,52.7%的人表现出病理性SDF (≥30%).

Infertility in Males
258
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
102.3K
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...

Infertility in Females
289
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
