概括
冷胚胎移植方案会影响母亲的甲状腺激素,但甲状腺刺激激素在母亲和新生儿中保持稳定. 编程周期显示甲状腺素水平较高,但女性及其婴儿的内分泌健康不受影响.
科学领域:
- 生殖内分泌学 生殖内分泌学
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 甲状腺生理学甲状腺生理学
背景情况:
- 在怀孕期间,甲状腺功能至关重要.
- 冷胚胎移植 (FET) 协议各不相同,可能会影响母亲的内分泌状态.
- 了解不同FET疗法对甲状腺功能的影响对于优化结果至关重要.
研究的目的:
- 为了比较经过修改的自然,编程和淋巴腺素刺激的冷胚胎移植周期对母亲甲状腺激素水平的影响.
- 评估这些FET疗法对新生儿甲状腺功能的影响.
- 为不同FET协议的内分泌安全提供基于证据的见解.
主要方法:
- 一项随机对照试验的二次分析,该试验涉及251名接受FET的女性.
- 分类为排卵 (修改的自然与编程) 和无排卵 (淋巴腺素刺激与编程) 组.
- 通过查测量母亲的甲状腺刺激激素 (TSH),自由甲状腺素 (fT4),总甲状腺素 (tT4) 和总三甲状腺素 (tT3);新生儿的TSH.
主要成果:
- 编程周期在准备和早期怀孕期间显示出明显更高的母体tT3和tT4.
- 在编程与修改的自然循环中观察到母体fT4的升高,但不是与淋巴腺素刺激的循环相比.
- 在所有研究的FET疗程中,母亲和新生儿的TSH水平是可比的.
结论:
- 编程的FET循环会导致母亲的甲状腺素水平提高,但不会对母亲或新生儿的TSH产生不良影响.
- 这些发现表明,编程的FET循环对女性及其新生儿来说都是内分泌安全的.
- 令人放心的证据支持通过编程FET周期怀孕的个体的内分泌健康.

In Vitro Fertilization
829
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...

Synthesis and Regulation of Thyroid Hormones
7.0K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Functions of Thyroid Hormones

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
