概括
患有极度严重寡精子症 (精子度≤100万/毫升) 的男性,随着时间的推移,患上二次性精子症的风险明显更高. 低丸激素水平进一步增加了这种风险,因此需要考虑精子储存.
科学领域:
- 生殖内分泌学 生殖内分泌学
- 男人不孕症研究研究
- 精子生成研究 精子生成研究
背景情况:
- 低精子度的Oligospermia,影响男性的生育能力.
- 异形二次性精子缺血症 (ISA) 是先前被诊断为小精子缺血症的男性发生精子缺血症.
- 了解ISA的进展和风险因素对于生殖咨询至关重要.
研究的目的:
- 为了确定ISA的发病率在男性的小精子症.
- 识别随着时间的推移,ISA发展的预测因素.
- 评估小精子精子严重程度对ISA风险的影响.
主要方法:
- 追溯性队列研究,对1056名小精子男性进行了连续精液分析.
- 小精子症的分类为轻度 (5-15 M/ml),严重 (1-5 M/ml) 和极度严重 (≤1 M/ml) 的组.
- 基于初始精子度和随访持续时间的ISA发生的分析.
主要成果:
- 在研究期间,2.9%的寡种男性患上了ISA.
- 与严重 (4.8%) 和轻度 (0%) 组相比,患有极度严重的寡精子症 (≤1M/ml) 的男性显示出显著更高的ISA率 (21.1%在3-5年,32%在5年).
- 初始精子度≤1M/ml (OR 22.12) 和更长的随访 (≥5年) 是ISA的强有力的预测因素;低与负相关 (OR 0.88).
结论:
- 患有极度严重的小精子症 (≤1M/ml) 的男性,特别是那些丸激素低的人,面临患二次性亚精子症的风险大幅增加.
- 精子储存强烈推给小精子症≤1M/ml的男性,因为进化为亚精子症的风险很高.
- 精子度>1M/ml的男性患阿佐精子症的概率很低,即使随访时间长.

Infertility in Males
259
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...

Oogenesis
63.6K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Menopause
154
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Meiosis II
183.3K
Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each...

Nondisjunction
75.5K
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.
