概括
新鲜样本中的总运动精子数 (TMSC) 预测了细胞内精子注射 (ICSI) 周期中的卵子受精和活产率. 选择后的TMSC没有显示出对受精的类似预测值.
科学领域:
- 生殖医学 生殖医学
- 不孕症研究 不孕症研究
- 精子分析 精子分析
背景情况:
- 内细胞质精子注射 (ICSI) 是男性不孕症的关键治疗方法.
- 对ICSI成功的预测标记对于患者咨询和治疗优化至关重要.
- 总运动精子数 (TMSC) 是精子质量的衡量标准,但其在ICSI中的预测价值仍在争论中.
研究的目的:
- 为了调查新鲜和选择后的总运动精子数 (TMSC) 是否可以预测细胞体内精子注射 (ICSI) 的结果.
- 评估基线TMSC与各种ICSI成功指标之间的相关性,包括活产和受精率.
主要方法:
- 一个多中心的回顾性队列研究,5813对夫妇接受ICSI.
- 参与者根据基线TMSC (从<100万到>2000万) 被分为五组.
- 主要结果:累积活产率;次要结果:受精率,胚胎质量,怀孕率和流产率.
主要成果:
- 调整后的分析显示,与最低的TMSC组相比,所有组的新鲜TMSC和卵细胞受精率之间存在正相关性 (P < 0.001).
- 新鲜TMSC对累积活产率产生了积极的影响 (调整HR1.25,P=0.0116),特别是在考虑受精卵子时.
- 没有观察到胚胎质量,怀孕率或流产率的显著差异,选择后的TMSC没有预测受精率.
结论:
- 基线TMSC是卵细胞受精率的重要预测因素,并影响ICSI中的累积活产率.
- 正如新鲜的TMSC所指出的精子质量,在ICSI成功中起着至关重要的作用.
- 虽然TMSC很重要,但其他女性和男性因素也会对整体ICSI结果产生影响.

Infertility in Males
512
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
3.6K
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.

Sperm Structure and Semen Composition
10.0K
During ejaculation, males release around 2-5 milliliters of semen, which is a complex mixture of mature sperm and various fluids produced by accessory glands. The mature sperm cells measure approximately 60 micrometers in length and consist of a head, neck, midpiece, and tail. The head is flattened and tapered, measuring about 4 to 5 micrometers in length. It contains a nucleus with condensed chromosomes and an acrosome, a cap-like structure filled with enzymes essential for penetrating the...

Sperm Transport
3.0K
The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.
