Samples of human endometrium were maintained in organ culture for 6 days on growth
medium. On Day 6, ultrastructural studies were performed on endometrial expiants,
demonstrating that human endometrium grown in organ culture preserved its normal structure.
The effect of oestrone sulphate was studied on the endometrium expiants. The endometrium
was cultured on harvest medium for 4 days to ensure the complete removal of endogenous
steroids, the tissues were then incubated with 10−7 M oestrone sulphate for 24 h. The oestrone sulphatase known to interfere with oestrone
sulphate metabolism was present in endometrial organ culture. By incubation with estrone
sulphate for 24 h it was demonstrated that oestrone sulphate is hydrolysed to active
oestrogens.
