| pubmed-article:6783694 | pubmed:abstractText | Urinary estrone and estradiol levels have been measured using an enzymatic method during the late lutheal phase in 17 female volunteers trying for a pregnancy and in 10 patients having a treatment for stimulation of ovulation. The profile of urinary estrogenic excretion appears to be different if a pregnancy started or not during the studied cycle. These patterns allow a good diagnostic presumption before the following missing menses, which can be useful when dealing with women treated for infertility and when plasmatic dosage of hCG or beta hCG cannot be rapidly available. | lld:pubmed |
