概括
患有克莱因费尔特综合征的男性的精子检索率在年轻成年人 (20-29岁) 中高于青少年. 具有生殖细胞的丸组织学在年轻男性中更为常见,但不能保证成功的精子采集.
科学领域:
- 生殖医学 生殖医学
- 安德罗学与人类学
- 遗传学 是一个遗传学.
背景情况:
- 克莱因菲尔特综合征 (KS) 是一种常见的影响男性的遗传疾病,其特点是存在额外的X染色体.
- 精是KS的常见并发症,影响生育能力.
- 微切割丸精子提取 (micro-TESE) 为患有KS的亚精子雄性提供了一个潜在的生育解决方案.
研究的目的:
- 研究Klinefelter综合征男性年龄,丸组织学和精子检索成功之间的关系.
- 确定KS男性精子采集程序的最佳时间.
主要方法:
- 对217名患有KS的男性进行了回顾性分析,这些男性在1995年至2020年期间接受了微型TESE.
- 患者被分为青少年 (<20岁) 和成人 (≥20岁) 组,成年人根据年龄十年进一步分层.
- 统计分析包括千平方测试和多变量后勤回归,以确定与成功提取精子相关的因素.
主要成果:
- 精子检索率在20-29岁的成年人中显著更高 (71%),而不是青少年 (53%) 和40岁以上的人 (13%).
- 在17%的青少年中观察到含有生殖细胞的丸组织学,随着年龄的增长而下降,但与更高的精子检索率无关.
- 丸活检的低精子生成独立地与成功提取精子的几率增加有关 (OR 5.8,P=.03).
结论:
- 虽然生殖细胞在患有KS的年轻男性中更为普遍,但这并不意味着精子提取的可能性更高.
- 患有KS的亚精子男性的精子采集可以在年轻成人时期成功进行,青春期不是先决条件.
- 生殖泌尿科医生应向患者建议,通过精子采集来保护生育能力在年轻成年时是可行的和有效的.

01:23Infertility in Males
276
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...

01:27Testes: Histology
962
A tough, fibrous membrane, the tunica albuginea, covers the testes, extending inward to form fibrous partitions or septa, dividing them into internal compartments called lobules. Each lobule has 1 to 3 tightly coiled seminiferous tubules where sperm production occurs. These tubules merge into a tubular network at the back of the testis, known as the rete testis. It connects to 15 to 20 efferent ductules, leading to the epididymis.

01:19Testes: Gross Anatomy
2.2K
The testes, also known as testicles, are the male gonads. They are housed within the scrotum, a sac-like structure located beneath the penis. The scrotum's primary role is to regulate the temperature of the testes, which is crucial for sperm production.
Each testis is surrounded by the tunica albuginea, a dense connective tissue layer that provides structural support and protection. This layer is covered by an outer serous membrane called the tunica vaginalis, which helps reduce friction...

01:41Spermatogenesis
102.6K
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...

02:19The Y Chromosome Determines Maleness
6.6K
The Y chromosome is a sex chromosome found in several vertebrates and mammals, including humans. In addition to 22 pairs of autosomes, the human males have one X chromosome and one Y chromosome. In these organisms, the presence or absence of the Y chromosome determines the development of male traits.
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size....

01:26Testosterone: Functions and Regulation
696
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
