Checking the function of the ovaries, corpus luteum, and placenta

Both estrogen and progesterone are female hormones secreted by the ovaries.

Estrogen plays a role in maintaining the first half of the sexual cycle, such as the expression of female secondary sexual characteristics, maintaining reproductive function, maturation of ovarian follicles, promoting ovulation, and proliferation of the endometrium.

On the other hand, progesterone plays a role in maintaining the latter half of the sexual cycle, such as inhibiting follicular development, thickening the endometrium, and maintaining pregnancy.

These hormones are tested when examining ovarian, corpus luteum, and placental function.

Measures based on test results

Estrogen and progesterone values ​​vary greatly between individuals, by gender, and by age and menstrual cycle, so these are taken into consideration when interpreting them.

In other words, rather than making a diagnosis based on a single measurement, measurements are taken several times on different days and the measurement values ​​are then comprehensively judged.

The main diseases suspected are

Estrogen

High level → estrogen-producing tumor, congenital adrenal enzyme deficiency

Low value → ovarian insufficiency, luteal insufficiency

Progesterone

High level → Use of ovulation inducers

Low value → ovarian insufficiency, luteal insufficiency

The general terms used by doctors are "estrogen" and "progesterone"

基準値

 エストロゲン(尿検査)

 男性:2~20μg/日

 女性:卵胞期 3~20μg/日

    排卵期 10~60μg/日

    黄体期 8~50μg/日

    閉経期 10μg/日以下

 プロゲステロン(血液検査)

 男性:0.4ng/mℓ以下

 女性:卵胞期  0.1~1.5ng/mℓ

    黄体期  2.5~28.0ng/mℓ

    黄体中期 5.7~28.0ng/mℓ

    閉経期  0.2ng/mℓ以下

卵巣や黄体、胎盤の機能などをチェック

 エストロゲン、プロゲステロンともに卵巣から分泌される女性ホルモンです。

 エストロゲンは、女性の第二次性徴の発現、生殖機能維持や卵胞の成熟、排卵促進、子宮内膜の増殖などの性周期の前半を維持する役割を果たしています。

 一方、プロゲステロンは、卵胞発育の抑制などの性周期後半の維持、子宮内膜の肥厚、妊娠持続作用などの役割を果たしています。

 これらのホルモンは、卵巣や黄体、胎盤の機能を調べるときに検査します。

検査値からの対策

 エストロゲンやプロゲステロンの値は、性差・個人差・年齢別変動・月経周期変動が極めて大きいため、これらを考慮して解釈しています。

 すなわち、1回の測定で診断を行うのでなく、日をかえて何回か測定し、その測定値を総合的に判定します。

疑われるおもな病気などは

◆エストロゲン

  高値→エストロゲン産生腫瘍、先天性副腎酵素欠損症

  低値→卵巣機能不全、黄体機能不全

◆プロゲステロン

  高値→排卵誘発剤使用

  低値→卵巣機能不全、黄体機能不全

医師が使う一般用語
「エストロゲン」「プロゲステロン」
