概括
丸微石 (TM) 似乎不会影响丸的免疫特权,也不会增加抗精子抗体 (ASA) 的风险. 这项大型研究表明,例行ASA测试对于有偶发TM的男性是不必要的.
科学领域:
- 生殖性泌尿器科 生殖性泌尿器科
- 免疫学 免疫学 免疫学
- 安德罗学与人类学
背景情况:
- 丸微石 (TM) 是一种状况,其特征在于丸内存在小的化.
- 有一种普遍的假设是TM可能会损害丸免疫特权,可能导致抗精子抗体 (ASA) 的发展.
研究的目的:
- 调查丸微结石病与大量不育男性中抗精子抗体的患病率之间的联系.
- 评估TM是否影响丸免疫特权和精液参数.
主要方法:
- 在2001年至2022年期间,对1755名不育男性进行了精液分析和阴囊超声波的回顾性分析.
- 使用直接IgG混合抗球蛋白反应 (MAR) 试验量化了抗精子抗体 (ASA),结合率≥50%,被认为具有临床意义.
- 在不同组之间比较了TM和ASA阳性的患病率,以及精液参数和切除术史.
主要成果:
- 在9.5%的研究人口 (167名男性) 中,鉴定出丸微石.
- 在有TM (1.2%) 和没有TM (3.5%) 的男性中,ASA阳性率相似,没有统计学上显著的差异 (p=0.17).
- 精液参数在两组之间是可比的;然而,在患有TM的男性中,先前切除术的病史更为频繁.
结论:
- 这一大型队列的研究结果表明,丸微石病不会损害丸免疫特权,也不会促进抗精子抗体的产生.
- 在偶发的丸微石病的情况下,不支持对抗精子抗体的常规测试.
- 进一步的研究可能会探索先前在TM男性中进行切除术的含义.

The Evidence for Evolution
48.4K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Infertility in Males
579
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...

Infertility in Females
4.9K
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.

Design Example: Maintaining Level of an Embankment
446
Constructing a roadway embankment over uneven terrain requires precise leveling to ensure stability and proper drainage. Surveyors use a leveling instrument and staff to calculate ground elevations and determine the required fill material at each point along the embankment alignment.The process begins by positioning a leveling instrument near a benchmark with a known elevation. A backsight reading establishes the instrument height, which serves as a reference for subsequent measurements. A...
