ABSTRACT The plasma levels of luteinizing hormone (LH) and progesterone and the urinary excretion of LH and oestrogens were measured during the normal menstrual cycle of 22 young and healthy women. A total of 42 cycles were investigated. The urinary excretion of total oestrogens increased during several days before the rise of LH in the urine. The day of maximum excretion of LH and total oestrogens coincided during the midcycle period. The mid-cyclic rise in LH was found to occur on the same day in the plasma and urine and the days of maximum values coincided in 11 out of 16 cycles. In 5 cycles the maximum level was reached one day later in the urine. The plasma levels of progesterone started to increase during the LH and oestrogen peaks. The days for maximum levels of progesterone coincided with the second peak of urinary oestrogens. The levels of progesterone in the plasma reached values above 10 ng per ml in all normal cycles. The plasma levels of progesterone were below 1 ng per ml plasma when menstrual bleeding started. The length of the luteal phase was 14.4 ± 1.1 (s) days. The sum of daily urinary excretion of total oestrogens and the sum of the daily plasma progesterone levels varied within 15 per cent of the mean in five out of six women studied during more than two cycles. The variation in values for the sums of daily oestrogen excretion and plasma progesterone levels was considerably larger between menstrual cycles of different women than between menstrual cycles of the same woman.

ABSTRACT Daily determinations of the plasma level of progesterone and the urinary excretion of LH and oestrogens were performed in four women during one control cycle followed by three months of daily treatment with 0.1 mg of norethindrone. According to the plasma progesterone pattern, all four women seemed to ovulate during their control cycle. Two women became pregnant during their second cycle of treatment. During treatment all four women showed an atypical LH pattern without any distinct midcycle peak. The mean LH excretion during treatment was not significantly different from the mean level of follicular phase of normal cycles. The oestrogens and progesterone levels were within normal ranges. It is concluded that during treatment with 0.1 mg of norethindrone daily an apparently normal pregnancy may occur in spite of a different LH excretion pattern.

ABSTRACT Daily determinations of the plasma level of progesterone and the urinary excretion of luteinizing hormone (LH) and total oestrogens were performed in 6 subjects during one control cycle, immediately followed by three cycles of daily treatment with 0.5 mg of chlormadinone acetate continuously. The control cycles were ovulatory according to the parameters investigated. Two of the women showed a normal LH excretion pattern in all treatment cycles. The four other subjects also had periodical variations in the LH excretion but no distinct midcycle peaks occurred. The mean oestrogen excretion was increased in all three treatment cycles but the difference was satistically significant only in the last two cycles. Compared with the treatment cycles, the sum of progesterone values was significantly decreased in the first two cycles. Chlormadinone acetate in this dose had no thermogenic effect. Three of the subjects showed bleeding irregularities which had no clear connection with the hormone variations measured in the study. It is suggested that the low levels of progesterone might be due to a defective corpus luteum function.

ABSTRACT The effect of orally given diethylstilboestroldiphosphate (DES) and 17α-ethinyl-oestradiol-3-methylether (EEM) on plasma progesterone levels was studied. Both compounds were administered for 5 days to 5 women in daily doses of 60 mg (DES) and 30 mg (EEM). The fully informed volunteers were found to have a normal menstrual cycle before the study. The mean corpus luteum phase (corpus luteum phase = days between LH surge and onset of menstruation) of all control cycles lasted 12.8 days. Daily plasma samples were collected for radioimmunoassay (RIA) of progesterone, immunoreactive oestrogens and LH. After a control cycle the first treatment was carried out with DES. The third and the fifth cycle were control cycles again. The EEM-treatment was done in the fourth cycle. Although the effect of the two compounds was different, a dependence of the age of the corpus luteum (CL) could be demonstrated for both. DES-treatment lowered plasma progesterone levels during administration. This effect was only demonstrable if the treatment was begun on the day of the LH-peak. The length of the CL-phase remained unaltered. EEM-treatment if started on the day of the LH surge, suppressed corpus luteum function in the late luteal phase. If the treatment was started later, the effect was less pronounced. The administration of both compounds did not shorten the time between ovulation and the next bleeding. After DES-treatment this interval was not altered. After EEM-treatment the subsequent bleeding was even delayed depending on slowly decreasing levels of plasma oestrogens.

ABSTRACT The levels of oestrone (E1)*, oestradiol-17β (E2) and progesterone (P) were determined simultaneously by radioimmunoassay in serial peripheral plasma samples from 11 rhesus monkeys (Macaca mulatta) during ovulatory menstrual cycles. In 3 other monkeys luteectomy was performed on day 20 or 21 of the menstrual cycle. The mean plasma levels of oestradiol-17β predominated over the mean E1 during the follicular phase, but during the luteal phase the E1 and E2 patterns varied widely. Before menstruation, increased or unchanged levels of E1 and E2 were mostly found. The decrease found in a few monkeys never reached the low levels found during the days after the midcycle peak. The plasma levels of progesterone increased from less than 0.2 ng/ml during the follicular phase to maximal values within 3 to 4 days after the midcycle peak of oestradiol-17β. The plasma levels of progesterone decreased to less than 1 ng/ml and remained low for 3 to 5 days before menstruation. In the luteectomized monkeys the plasma levels of P, E1 and E2 fell dramatically within 24 h and vaginal bleeding was detected within 72 h post-operatively. In 2 of the 3 luteectomized monkeys the levels of E1 and E2 increased before the bleeding. The ratio of oestrogens (oestradiol-17β and oestrone) over progesterone changed markedly in favour of the oestrogens during the pre-menstrual period. It is concluded that the patterns of progesterone and oestrogens are divergent during the luteal phase. The maximal levels of progesterone are reached early while the maximal levels of oestrogens are reached later during the luteal phase.

ABSTRACT The peripheral plasma levels of luteinizing hormone (LH) as measured by an in vitro bioassay method were determined in daily plasma samples collected throughout one menstrual cycle in 8 normally menstruating baboons (Papio hamadryas). In addition LH was measured in plasma at three hourly intervals throughout the day in the follicular, peri-ovulatory and luteal phases of the cycle in 7, 3 and 6 animals respectively. The plasma levels of progesterone and oestradiol were also determined in the same samples throughout the menstrual cycle and during the period of the midcycle LH surge. The circulating LH profile measured throughout the cycle was characterized by a sharp mid-cycle surge (completed within one day) which was followed by a series of LH surges of varying intensity during the luteal phase of the cycle. The initial surge was considered to be pre-ovulatory as indicated by its relationship to the peak of plasma oestradiol and to the first significant increase in the levels of plasma progesterone above values found earlier in the follicular phase. A circadian rhythm of LH was observed during the luteal phase of the cycle; a 3 fold rise in LH was noted during the hours 15.00 to 24.00. No differences were observed throughout the day in the follicular phase of the cycle. The LH profile in three animals studied during the mid-cycle LH surge showed pronounced circadian changes with a major peak at 24.00 h. Plasma progesterone levels during this period rose sharply to values normally found in the mid-luteal phase of the cycle. A comparison of plasma levels of biologically active LH during the menstrual cycle of the baboon with those found in normally menstruating women reveals that in the baboon the LH peak is of much shorter duration and the levels in the follicular and peri-menstrual phases are significantly lower than in the human.

ABSTRACT In an attempt to analyze the multiple changes and interactions in circulating steroid levels in the peri-ovulatory and peri-menstrual periods, the plasma levels of immunoreactive luteinizing hormone (LH), progesterone and unconjugated pregnenolone, dehydroepiandrosterone, testosterone, oestradiol and oestrone were assayed daily during a complete cycle in 17 normally menstruating women. In 14 of the 17 subjects studied androstenedione and unconjugated dihydrotestosterone were also estimated. The day of the LH-peak and the first day of menstruation, respectively, were used to synchronize the peri-ovulatory and peri-menstrual plasma levels of the various steroids. With the exception of dehydroepiandrosterone and dihydrotestosterone, the plasma levels of all steroids exhibited significant, but different changes during the cycle. Testosterone levels showed a slight but significant increase around the LH-peak, whereas the levels of pregnenolone and androstenedione were higher in the post-ovulatory than in the pre-ovulatory periods. The levels of oestradiol and oestrone, as well as the ratios of oestradiol to oestrone gradually increased from the low values observed in the early proliferative phase to pre-ovulatory peak values. The relationship between peaks of oestradiol and oestrone and that of LH exhibited great individual variation. The same was true for the individual oestradiol to oestrone ratios. The combination of several steroidal signals did not improve the predictive value of the analyses. However, an increase of individual progesterone values by at least 0.35 ng/ml from the day preceding the LH-peak to the day of the LH-peak was observed in 13 of the 17 subjects. It is suggested that for the early detection of the LH surge and prediction of the subsequent ovulation daily assays of plasma progesterone are of more value than the assay of the other steroids investigated.

Abstract. The disappearance rate of [D-Ser(t-bu)6,des-Gly10]GnRH ethylamide (Buserelin®, HOE 766) was studied in plasma and urine after intranasal (300 μg) or sc (10 μg/kg) administration. A radioimmunoassay for HOE 766 was developed using 125I[D-Trp6,Des-Gly10]GnRH ethylamide as tracer and an antiserum raised against HOE 766. Cross-reaction with native GnRH was only 1.7%. Sensitivity was 1 pg/tube. In 6 male adolescents, the mean plasma HOE 766 concentration (± sem) was 0.46 ± 0.08, 0.50 ± 0.10, 0.28 ± 0.04, 0.24 ± 0.04, 0.13 ± 0.03, and 0.08 ± 0.02 μg/l 30, 60, 90, 120 and 180 min after the intranasal administration, respectively. Concomitant urinary excretion of HOE 766-like material was 9.43 ± 1.96 μg/4 h. There was a good correlation between integrated plasma levels and urinary excretion (r = 0.92). In the same 6 volunteers, the plasma HOE 766 levels were 21.2 ± 3.0, 25.9 ± 0.8, 21.2 ± 0.9, 17.1 ± 0.7, 12.8 ± 1.1, 8.9 ± 0.4, and 5.9 ± 0.8 μg/l 20, 40, 60, 90, 120, 180 and 240 min after sc injection, respectively. The mean urinary excretion was 543 ± 61 μg/4 h. In two girls with precocious puberty treated during 12 to 15 months with intranasal administration of HOE 766, urinary excretion of HOE 766-like material was shown to correlate well with the degree of inhibition of plasma 17β-E2and of plasma LH and FSH responses to a GnRH challenge. Thus, monitoring of HOE 766 in urine appears to be helpful for evaluating of intranasal therapy with a GnRH analog in precocious puberty.

Abstract. Domestic buffaloes were used to characterize the pattern of progesterone, oestradiol-17β, LH and androgen in the systemic circulation following infertile insemination. Concentrations of hormones were measured by RIA in blood samples collected daily or at alternate days following insemination. The concentration of progesterone was lowest on the day of insemination, and increased significantly to a peak level of 4.00 ± 0.60 ng/ml by day 13 post insemination. After day 17, it declined significantly (P < 0.01) to reach low levels by day 21. The concentration of oestradiol-17β was high at the time of insemination and declined significantly (P < 0.01) by day 2 after insemination. It was maintained around the basal level till day 18 with minor peaks in between this period. It again rose significantly (P < 0.01) at subsequent oestrus. The mean level of LH was highest at the time of insemination, and declined significantly (P < 0.01) by day 1 post insemination. It did not vary appreciably till the animal returned to oestrus. The oestrous value of LH and progesterone were negatively correlated (r = −0.77). The androgen level was observed to be high at insemination in 3 out of 5 animals, but the overall pattern of this steroid was inconsistent during the period studied. A high concentration of androgen was recorded in all the animals from day 2–5 before the onset of oestrus.

SUMMARY The daily urinary excretion of luteinizing hormone (LH) was determined in 15 boys, aged 5–11 yr., and in 15 adult men, aged 18–65 yr., by an immunological method using the haemagglutination inhibition system. The hormone was detected in every subject investigated. The mean value for urinary LH excretion in boys was equivalent to 3·4 i.u./24 hr. (range 1·3–6·5) and was 29·3 i.u./24 hr. in adults (range 15·4–44·6). The mean adult: child ratio was 8·6. There was a significant increase in LH output with age in both the boys and the men; the rate of this increase was the same in both groups. However, there was a sharp rise in hormone output at about the onset of puberty.

CONTEXT: Endometrial maturation, important in the diagnosis of infertile couples, has been evaluated since 1950 using the Noyes criteria. Nevertheless, there is no consensus regarding the most suitable period of the luteal phase for performing the biopsy. OBJETIVE: This study evaluated the correlation between the histological dating of two endometrial biopsies performed in the same menstrual cycle, on luteal phase days six and ten. DESIGN: Prospective study. SETTING: Human Reproduction Division of the Federal University of São Paulo, referral center. PATIENTS:Twenty-five women complaining of infertility had their menstrual cycles monitored by ultrasound and LH plasma levels, to obtain evidence of ovulation. PROCEDURES: Endometrial biopsies were performed on luteal phase days LH+6 and LH+10 (luteal phase day 1 = LH+1 = the day that follows LH peak). Dating was done according to morphometric criteria, in which an endometrium sample is considered out of phase if the minimum maturation delay is one day. On day LH+6, blood was drawn for plasma progesterone level determination. RESULTS: All patients had an ovulatory cycle (mean LH peak: 47.4 U/L; mean follicular diameter on LH peak day: 18.9 mm; mean endometrial thickness on LH peak day: 10.3 mm; mean plasma progesterone level on day LH+6: 14.4 ng/ml). 14 patients had both biopsies in phase; 5 patients had out of phase biopsies only on day LH+6; 3 had out of phase biopsies only on day LH+10 and 3 patients had out of phase biopsies on both days. McNemar's test showed no statistical difference between these data (p>33.36%). CONCLUSIONS: The correlation found between the endometrial datings suggests that biopsies performed on either of these two days are suitable for evaluation of endometrial maturation.
