概括

试管婴儿 (IVF) 和细胞内精子注射 (ICSI) 是有效的治疗子精症. 有时需要救援ICSI (R-ICSI),但中度和重度病例的结果相似.

科学领域:

生殖医学生殖医学
安德罗学与人类学
胚胎学胚胎学

背景情况:

以异常的精子形态为特征的teratozoospermia是男性不孕症的常见原因之一.
对于孤立的特拉精子症的最佳辅助生殖技术 (ART) 策略仍在争论中.

研究的目的:

为了评估体外受精 (IVF) 与细胞内质精子注射 (ICSI) 的疗效,在患有隔离性高精子症的患者中.
为了比较胚胎学结果和中度和重度精子群之间的救援ICSI (R-ICSI) 的需要.

主要方法:

在2018-2022年间进行IVF/ICSI的81对患有隔离性精子症的夫妇的回顾性分析.
胚胎学数据的比较,包括囊胚发育和R-ICSI率,在中度和严重的三种子精群之间.

主要成果:

在中度 (18.33%) 和重度 (14.29%) 类精子群之间,R-ICSI率没有统计学上显著的差异.
胚胎学结果,如囊胚发育,在两组之间没有显著差异.
试管婴儿对中度和重度的三种子精有效,根据需要使用R-ICSI.

结论:

患有中度和重度隔离性三种子精的患者可以通过试管婴儿进行有效管理.
在这些患者体外受精期间发生受精失败时,救援ICSI (R-ICSI) 是一种可行的选择.
这项研究为不育患者在选择适当的精计划时提供了参考.

Spermatogenesis

Spermatogenesis

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...

Fertilization

Fertilization

During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...

Sperm Structure and Semen Composition

Sperm Structure and Semen Composition

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...

Infertility in Males

Infertility in Males

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...
