OBJECTIVE: To understand the physiologic effects and secretion pattern of inhibin A and inhibin B throughout menstrual cycle in the normal reproductive women, serum values of inhibin A and inhibin B were measured. METHODS: Inhibin A and inhibin B levels were measured in 320 serum samples from 160 normal reproductive women by solid phase sandwich ELISA. RESULTS: In the normal reproductive women, inhibin A is secreted in low serum levels until the mid- proliferative phase, begins to increase in the late proliferative phase (16.53+/-1.57 pg/ml), reaches the peak in the early secretory and mid-secretory phase (45.56+/-2.37 and 45.85+/-2.08 pg/ml), and subsequently decreases in the late secretory phase. We found that inhibin B begins to increase in the early proliferative phase (65.40+/-4.08 pg/ml), is secreted in high concentration in the proliferative phase, reaches the peak in the ovulatory phase (110.74+/-9.83 pg/ml), and thereafter declines rapidly to the lowest level in the mid-secretory phase (29.59+/-2.08 pg/ml). CONCLUSION: In conclusion, serum inhibin A levels peak during the luteal phase, indicating the greatest production by the corpus luteum and serum inhibin B levels increase during the follicular phase, indicating the greatest production by follicles in early stage of development. Inhibin A is associated with the luteal function and inhibin B, the follicular function. Both inhibins are associated with the follicular maturation and development.

BACKGROUND/AIMS: The female sex hormones are thought to affect gastrointestinal function. However, the relationship between female sex hormone and gastrointestinal function has not been identified. The aim of this study was to evaluate the relationship between constipation and hormonal changes in young women and to find the difference of colon transit time (CTT) across the menstrual cycle. METHODS: Two hundred and five students completed questionnaires. CTT as well as serum estradiol and progesterone levels were measured in 15 regularly menstruating volunteers. RESULTS: One hundred and six experienced changes in bowel habit across menstrual cycle. The mean estradiol concentration in the follicular phase was not significantly different from that in the luteal phase (118.0 +/- 28.8 pg/mL vs. 76.9 +/- 10.5 pg/mL, p > 0.05). The mean progesterone concentration in the luteal phase was significantly higher than that in the follicular phase (3.0 +/- 0.9 ng/mL vs. 1.2 +/- 0.4 ng/mL, p < 0.05). The mean CTT was not significantly delayed in the luteal phase than the time in the follicular phase (45 +/- 20 vs. 35 +/- 22 hours, p > 0.05). However, CTT was delayed at the progesterone peak in 11 of 15 (73.3%) women. CONCLUSIONS: Our study suggested a possible role of female sex hormones as a cause of constipation in young women.

OBJECTIVES: It was reported that symptoms change according to menstrual cycles, aggravation of symptoms 3 to 7 days before menstruation in bipolar disorder for example. Therefore, this study was to investigate the correlation among the change of symptoms, serum lithium level, estradiol and progesterone levels. METHODS: For women with bipolar disorder, we divided by menstrual cycle into three groups; middle follicular phase, middle luteal phase and late luteal phase. We estimated serum lithiumlevel, estradiol and progesterone of each phase, and assessed the change of symptoms using Hamilton Rating Scale for Depression and Manic-State Rating Scale. Consequently they were divided into symptom changed group and not changed group. RESULTS: Serum lithium levels of patients with bipolar disorder were significantly decreased in middle luteal phase compared with in middle follicular phase, and it was sustained in low level to late follicular phase. Although there were no statistically significant differences, there was more decreased serum lithium level in symptom changed group than in symptom unchanged group. Serum lithium levels were not statistically correlated with both estradiol and progesterone levels. When symptom changed group was compared with symptom not changed group, there was a significant correlation between changes of symptom and estradiol level. CONCLUSION: The possible mechanism of the change of symptoms according to menstrual cycle in bipolar disorder may be in estrogen level and due to the effect of serum lithium level change according to menstrual cycle. The investigation of this mechanism will contribute to the treatment and the prevention of recurrence symptons in bipolar disorder.

Alteration in the hormone level associated with menstrual cycle influences the interaction between the urethra and bladder as well as detrusor function, maybe due to the common embryological origin of lower female genital and urinary tract. We tried to investigate the effect of the menstrual cycle on cystometric diagnosis through this retrospective study. 60 women with regular menstruation were enrolled in this study. The study groups were divided into 2 groups, Group I was women whose symptoms were not influenced by the menstrual cycle, Group II was women whose symptoms were adversely affected premenstrually. The majority of normal cystometric diagnosis were made in the luteal phase (Group I: 42.9% vs 4.4%, p<0.05; Group II: 50.0% vs 22.2%, p<0.05). But diagnosis of genuine stress incontinence, detrusor instability, mixed genuine stress incontinence and detrusor instability were frequently made in the follicular phase of mentruation. Normal cystometric diagnosis in the group II were more commom than the group II ( 36.8% vs 19.7%, p<0.05 ). The results of this study reveal that the timing of cystometric evaluation may influence the the detection of a positive diagnosis. In patients whose symptom are influenced by their menstrual cycle, the luteal phase may not be the correct time to make an accurate diagnosis.

BACKGOUND: This study was designed to examine the effects of female hormones and the menstrual cycle on postoperative pain. METHODS: Ninety women who underwent gynecologic surgery involving a lower abdominal incision were asked for information regarding their menstrual cycles, and blood samples were obtained to determine the progesterone and estrogen levels of the patients at the time of surgery. Patient controlled analgesia was applied to control postoperative pain and an estimate of the consumption of analgesic drugs by the patients was made. Analgesic consumption and pain scores were recorded at 2, 24, and 48 hours after operation. RESULTS: There was no relationship observed between the concentration of progesterone and estrogen and the consumption of analgesic drugs. However, patients that were in the luteal phase at the time of surgery consumed a significantly lower amount of analgesic drugs during the 2-24 hours following surgery than patients that were in the follicular phase (19.4 +/- 6.5 ml vs 24.6 +/- 11.0 ml, P < 0.05), Theree was, no significant difference in pain scores between two menstrual phases. CONCLUSIONS: This study demonstrates that there is less postoperative pain experienced by patients that are in the luteal phase of their menstrual cycle at the time of surgery than in patients that were in the follicular phase of their menstrual cycle, however, the results of this study did not reveal a relationship between the blood concentration of female hormones and postoperative pain.

OBJECTIVE: To determine if salivary ferning correlates significantly with sonographic indices in identifying the fertile period, and whether it may be used as a cheaper, and more convenient way to aid infertility patients in achieving pregnancy.

POPULATION: Subjects who complain of difficulty achieving pregnancy and for whom follicle monitoring was indicated were recruited from the Outpatient Department in a tertiary hospital in Manila.

METHODOLOGY: Patients (n=40) with Primary or Secondary Infertility from April 2013 to August 2015 who require serial follicle monitoring as part of infertility work up were recruited in the study. For every follicle monitoring by ultrasound done by one sonologist, a salivary sample was obtained from the subject and the ferning pattern was determined and recorded by one pathologist blinded as to the day of the subject's menstrual cycle.

RESULTS: There was a total of 40 subjects who underwent 2 serial follicle monitoring during the study. The 1 st TVS (preovulatory) was done between Day 9 to 14 of the cycle with an average of Day 11. Correspondingly, salivary ferning done showed that there were 26 (65.0%) with Salivary Ferning 1 pattern and 14 (35.0%) with Salivary Ferning 2 pattern (p=0.35). This showed no significant difference between follicle monitoring and salivary ferning pattern and either may be used in identifying fertile period preovulatory. The 2nd TVS (postovulatory) was done between Day 12 to 21 with an average of Day 16. All the second ultrasound findings showed signs of ovulation. Correspondingly, there were 1 (2.0%) showed Salivary Ferning 1 pattern, 11 (27.5%) showed Salivary Ferning 2 Pattern and 28 (70.0%) showed Salivary Ferning 3 Pattern 9 (p=0.05). This showed no significant difference between follicle monitoring and salivary ferning pattern, hence, TVS follicle monitoring remains more reliable in identifying that ovulation has occurred.

CONCLUSION: Salivary ferning corresponded well with ultrasonographic findings during the preovulatory phase of the cycle, while no correlation was noted between the salivary ferning pattern and the postovulatory phase of the cycle. Hence, sonographic follicle monitoring remains a better predictor of ovulation, and more effective in identifying the fertile period

Recurrent pregnancy loss (RPL) is defined as three or more consecutive spontaneous abortions. It affects about 1% of couples attempting pregnancy. Most of these pregnancy losses are unrecognized. Among the pregnancies that are clinically recognized, loss occurs in 15% before 20 weeks of gestation. Only about 50% of women with RPL have an identifiable etiology. Genetic abnormalities are responsible for RPL in 2~4% of these couples, most with balanced translocation. Luteal phase defect might be present in 25~30% of women with RPL; however, progesterone supplementation for miscarriage prevention has not been adequately studied. Uterine abnormalities might also result in RPL. Inherited thrombophilias appear to be associated with fetal death, and antenatal thromboprophylaxis might be beneficial for some women with an inherited thrombophilia. Antiphospholipid syndrome is known to cause RPL, and antenatal thromboprophylaxis reduces the risk of miscarriage. The evidence on alloimmune incompatibility as a cause of RPL is preliminary and no immunotherapy has been shown to be effective in the prevention of miscarriage. Recently a series of new factors that exhibit an association with RPL have been identified, and they might exhibit an additive or multiplicative effect on the RPL risk.

The effect of the menstrual cycle on the diurnal cortisol rhythm was investigated in 15 normally cyclic healthy women during reproductive life. Salivary cortisol was measured by radioimmunoassay in samples collected every 2 h for 24 h during the four phases of the menstrual cycle: menstrual phase, late follicular/peri-ovulation phase, early to mid luteal phase and late luteal phase, respectively. Distinct diurnal rhythms of free cortisol were found throughout the menstrual cycle by using a nonlinear periodic regression model. The model was characterized by an asymmetrically peaked diurnal cycle and ultradian harmonics. There was a trend to higher troughs and significantly shorter peak-width in phase II and phase IV compared to phase I. The ultradian amplitude in phase IV was significantly lower compared with phase I and showed a trend of decrease compared with phase II. The results suggest that the daily cortisol secretion is modulated by the phase of the menstrual cycle.
