概括
孕产妇的年龄会影响试管婴儿的成功,即使是使用捐赠卵子. 在45-49岁和≥50岁的妇女中,活产率下降,影响了围产期的结果.
科学领域:
- 生殖内分泌学 生殖内分泌学
- 在体外受精 (IVF)
- 母亲的年龄和生育能力
背景情况:
- 母亲年龄对试管婴儿的结果有很大影响,主要是由于与年龄相关的卵细胞染色体异常.
- 捐赠卵子通常用于减轻与年龄相关的卵子质量问题在试管婴儿中.
研究的目的:
- 为了调查IVF结果是否不同,在40岁及以上的患者使用捐赠卵细胞.
- 在捐赠卵子IVF的背景下,评估晚年母亲对活产率和围产期结果的影响.
主要方法:
- 从2015年1月1日到2021年12月31日进行的回顾性队列研究.
- 包括1660个单个胚胎移植周期使用捐赠卵子细胞的患者年龄≥40.
- 通过使用概括估计方程模型,对BMI,父亲年龄和周期类型进行控制,比较跨年龄组 (40-44,45-49,≥50) 的结果.
主要成果:
- 与40-44岁组相比,45-49岁年龄组的活产 (LB) 率明显较低 (P=0.023).
- 在≥50组中,LB率也较低,尽管在统计学上并不显著,可能是由于样本规模较小.
- 与40-44组相比,老年母亲年龄组 (45-49和≥50) 的出生体重明显较低 (P=0.004).
结论:
- 母亲年龄,独立于卵细胞质量,影响捐赠卵子IVF中的活产成就.
- 先进的孕产妇年龄 (≥45) 与降低活产率和降低出生体重有关,即使有捐赠卵细胞.
- 这些发现对于患者就使用捐赠卵细胞进行试管婴儿咨询至关重要.

Oogenesis
63.3K
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...

Meiosis vs. Mitosis
51.7K
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...

Menopause
110
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...

Ovarian Cycle
879
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

In Vitro Fertilization
176
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...
