Effect of oral administration of a continuous 18 day regimen of meloxicam on ovulation: experience of a randomized controlled trial
ArtÃculo de publicación ISIBackground: Cyclooxygenase-2 (COX-2) is expressed in all female reproductive organs. Therefore, inhibitors of COX-2 may affect
reproductive function. We evaluated the effect of extended administration of meloxicam on ovulation and the menstrual cycle. Our
hypothesis was that meloxicam administered from menstrual cycle day 5- 22 could interfere with follicular rupture, without disrupting the
menstrual cycle, and could be a potential non-hormonal contraceptive method.
Methods: The study was conducted in 56 healthy sterilized women. Before the onset of treatment and after the end of treatment, participants
were observed during a control cycle to ensure that they had progesterone (P4) serum levels (N12 nmol/l) consistent with ovulation.
Participants were treated for 18 days, during three consecutive cycles. They were randomized to 15 or 30 mg/day. The menstrual cycle was
monitored with serial ultrasound and hormone assays in blood.
Results: Fifty-six volunteers completed the study. In 55% of cycles treated with 15 mg/day and in 78% of cycles treated with 30mg/day
(pb0.001) we observed dysfunctional ovulation defined as follicular rupture not preceded 24–48 h earlier by an LH peak or preceded by a
blunted LH peak (b21 IU/l) or not followed by an elevated serum P4 level N12 nmol/l. Ovulation was observed in 44.6% and in 21.7% of
women in the lower dose group and the higher dose group, respectively. There were no differences between the two doses in other parameters
measured. There were no serious adverse events and adverse events were not different between doses or between control and treated cycles.
Conclusions: Although administration of meloxicam on menstrual cycle days 5- 22 resulted in a dose-dependent inhibition of ovulation,
more than 20% of subjects had normal ovulation with the highest dose.
Implications: Previous studies have shown that oral meloxicam can delay follicle rupture. This study investigated daily oral meloxicam as a
non-hormonal contraceptive. Since ovulation occurs in over 20% of cycles even with a high dose of 30 mg daily, it is not likely that the
approach would be a highly effective contraceptive strategy

Proteomic analysis of human follicular fluid from fertile women
BACKGROUND: Follicular fluid is a unique biological fluid in which the critical events of oocyte and follicular maturation and somatic cell-germ cell communication occur. Because of the intimate proximity of follicular fluid to the maturing oocyte, this fluid provides a unique window into the processes occurring during follicular maturation. A thorough identification of the specific components within follicular fluid may provide a better understanding of intrafollicular signaling, as well as reveal potential biomarkers of oocyte health for women undergoing assisted reproductive treatment. In this study, we used high and low pH HPLC peptide separations followed by mass spectrometry to perform a comprehensive proteomic analysis of human follicular fluid from healthy ovum donors. Next, using samples from a second set of patients, an isobaric mass tagging strategy for quantitative analysis was used to identify proteins with altered abundances after hCG treatment. RESULTS: A total of 742 follicular fluid proteins were identified in healthy ovum donors, including 413 that have not been previously reported. The proteins belong to diverse functional groups including insulin growth factor and insulin growth factor binding protein families, growth factor and related proteins, receptor signaling, defense/immunity, anti-apoptotic proteins, matrix metalloprotease related proteins, and complement activity. In a quantitative analysis, follicular fluid samples from age-matched women undergoing in vitro fertilization oocyte retrieval were compared and 17 follicular fluid proteins were found at significantly altered levels (p < 0.05) between pre-hCG and post-hCG samples. These proteins belong to a variety of functional processes, including protease inhibition, inflammation, and cell adhesion. CONCLUSIONS: This database of FF proteins significantly extends the known protein components present during the peri-ovulatory period and provides a useful basis for future studies comparing follicular fluid proteomes in various fertility, disease, and environmental exposure conditions. We identified 17 differentially expressed proteins after hCG treatment and together these data showed the feasibility for defining biomarkers that illuminate how the ovarian follicle microenvironment is altered in various infertility-related conditions.
