Detection of the ovulatory luteinizing hormone (LH) surge with a semiquantitative urinary LH assay

Urinary steroids, FSH and CG measurements for monitoring the ovarian cycle and pregnancy in the chimpanzee

“…For the past 30 years, various studies have shown that urinary steroids can be used to monitor menstrual cycle as well as early pregnancy in chimpanzees (e.g. [6, 11, 13, 20]). Also, chorionic gonadotropin (CG) has been used to detect pregnancy in chimpanzees [17].…”

Professional and Lay Interrater Reliability of Urinary Luteinizing Hormone Surges Measured by OvuQuick Test

“…Agreement on the occurrence or absence of an LH surge during any single month was assessed. While the validity of the OvuQuick Test has been supported by several studies (Elkind-Hirsch et al, 1986;Knee et al, 1985), further validation testing was conducted on a subsample of women in the current study. Women who lived within a 30-mile radius of the medical center were asked to have their blood serum progesterone levels tested 7 days after the LH surge indicated by the OvuQuick test pad.…”

“…Clinical studies have confirmed the prediction of ovulation based upon the OvuQuick test by the verification through ultrasonography of the presence of follicular collapse and by the verification in blood samples of plasma progesterone levels of greater than 5 ng/mL (Elkind-Hirsch et al, 1986;Knee et al, 1985). In a study of 1 2 women, LH surges detected using the OvuSTICK test (an earlier form of the OvuQuick test) were validated by serum progesterone levels and were found to have predicted ovulation correctly in all 16 cycles studied (Knee et al, 1985).…”

In another study, in which 14 women had transvaginal ultrasonography starting on day 12 of their cycle to detect follicle maturation, OvuSTICK determination of urine LH peaks was predictive of ovulation in 1 2 (86%) of the women (Vermesh, Kletzky, Davajan, & Israel, 1986).…”

“…N mone (LH) surges in urine provide a useful method for predicting ovulation (Elkind-Hirsch, Goldzieher, Gibbons, & Besch, 1986;Knee, Feinman, Strauss, Blasco, & Goodman, 1985). These tests have gained interest among clinicians, particularly in the area of infertility, because most other methods of predicting ovulation are expensive and require sophisticated equipment and trained personnel.…”
