We report here a young adult with a late presentation of aromatase deficiency to highlight the differences between the two conditions. A 27 year old lady presented to us with history of primary amenorrhea and masculine voice. [ncbi.nlm.nih.gov]

• Suggestibility

  The concentrations of estrone and 17β-estradiol precursors were comparable between groups, suggesting that placental aromatase is deficient in preeclampsia. [ncbi.nlm.nih.gov]

Following the examination by the family’s pediatrician, female pseudohermaphroditism was suspected, and a comprehensive workup was initiated. The hormonal changes in the mother before and after delivery are reported in Table 2. [academic.oup.com]

• Sperm Count Increased

  After 3 months of treatment, the sperm count increased (23.1 million/ml) and decreased rapidly (1.1 million/ml) during the following 3 months. The sperm motility was reduced at baseline and decreased further during treatment. [ncbi.nlm.nih.gov]

• Glucose Decreased

  AUC glucose decreased continuously after oral glucose load, and HOMA IR reached its lowest value the 75 microg weekly estradiol dose. This study confirms the role of estrogens in achieving bone mineralization and maturation in human males. [ncbi.nlm.nih.gov]

An iliac crest bone biopsy was performed only before and after the raloxifene treatment, but it was not repeated after transdermal estradiol treatment. [ncbi.nlm.nih.gov]

Etiology Aromatase ( CYP19A1, 15q21.1), or cytochrome P450, synthesizes estradiol from androgens. [orpha.net]

Abstract Female pseudohermaphroditism is caused by several etiologies. Here we report a case of aromatase deficiency who showed ambiguous genitalia and maternal virilization during pregnancy. [archive.org]

CONCLUSION: These results indicate that estrogen fluctuations may be an important factor in the etiology of bipolar disorder and it is obvious that more research on this topic is needed to clarify the role of estrogen in women with bipolar disorder. [epiphanyasd.blogspot.com]

This conversion in the placenta prevents androgens from directing sexual development in female fetuses. After birth, the conversion of androgens to estrogens takes place in multiple tissues. [ghr.nlm.nih.gov]
