Results and discussion

Results:
17 ß-estradiol is an estrogenic hormone occuring naturally in humans. Synthetic 17 ß-estradiol is a well-known drug substance and constituent of numerous approved drug products which have been in therapeutic use for many decades and the vast amount of clinical experience gained in its continued and widespread therapeutic use gives no evidence that 17 ß-estradiol, has a significant skin sensitizing potential.
