まとめ
事前のテストステロン性別肯定ホルモン療法(T-GAHT)を受けたトランスジェンダーおよびジェンダー多様性(TGD)患者は、胚盤胞数が少なかった。しかし、成熟卵母細胞の数は同等であり、IVFを希望した患者のほとんどが出産に至った。
科学分野:
- 生殖内分泌学
- 性別肯定ケア
- 体外受精
背景:
- 事前のテストステロン性別肯定ホルモン療法(T-GAHT)を受けたトランスジェンダーおよびジェンダー多様性(TGD)患者の胚の結果に関するデータは限られている。
- 以前の研究では、T-GAHT後の良好な卵母細胞収量が示唆されているが、胚盤胞形成能力は不明なままである。
研究 の 目的:
- 事前のT-GAHTを受けたTGD患者が、T-GAHTを受けていない患者と比較して、卵母細胞の凍結保存およびIVFの結果が異なるかどうかを調査すること。
- T-GAHTが成熟卵母細胞の収量および胚盤胞の発育に及ぼす影響を評価すること。
主な方法:
- 2013年1月から2024年3月までのTGD患者(出生時に女性と割り当てられた)46例の卵巣刺激周期の後ろ向き観察コホート研究。
- 事前のT-GAHTを受けた患者と受けていない患者の結果を比較し、成熟卵母細胞と胚盤胞形成を分析した。
- 電子カルテを使用してデータを収集し、主要な分析は完了した最初の周期で行った。
主要な成果:
- 事前のT-GAHTは、年齢で調整した後、総胚盤胞数および最高品質胚盤胞数の減少と関連していた。
- 成熟卵母細胞の回収数または成熟率に有意差は認められなかった。
- 初回周期での累積出生率は、事前のT-GAHT群では60%、T-GAHT非実施群では87.5%であった。
結論:
- 事前のT-GAHTは成熟卵母細胞数に違いをもたらさず、既存の文献と一致していた。
- 胚の結果不良は、事前のT-GAHTおよび中断期間の短さと関連していた。
- T-GAHT後のIVFを受けたTGD患者のほとんどが出産に至り、一般的に安心できる妊よう性を示唆している。

In Vitro Fertilization

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...

Testosterone: Functions and Regulation
2.2K
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...

Fertilization
91.1K
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...

Predicting Reaction Outcomes

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Impact of Individuals on Individuals

Human behavior is intricately shaped by social influences that arise from interactions with others in diverse contexts. These influences not only mold beliefs and attitudes but also drive the regulation of behaviors through both direct communication and observational learning. The study of these processes falls within the domain of social psychology, which seeks to understand how individuals are affected by and affect those around them.Mechanisms of Social InfluenceDirect social influence...

Outcomes of Glycolysis
107.1K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...
