Abstract
Background: Women having regular ovarian cycle often experience premenstrual syndrome which
may be associated with alterations of autonomic nerve function due to fluctuation of ovarian hormones
during different phases of ovarian cycle. Objective: To observe the parasympathetic nerve function
status and their relationships with ovarian hormones during different phases of ovarian cycle in
healthy young women. Methods: This cross sectional study was carried out in the department of
Physiology at BSMMU, Dhaka in 2007 on 30 eumenorrhogic healthy females aged 20 to 30 years.
Serum estrogen and progesterone were measured by MEIA method and parasympathetic nerve
functions were assessed by valsalva, deep breathing test and orthostatic test during follicular and
luteal phases of ovarian cycle. Data were analyzed by paired student ‘t’ test, and Pearson’s Correlation
coefficient test where applicable. Results: Mean resting HR,SBP,DBP and all measures of
parasympathetic nerve function were similar in all phases of ovarian cycle. With serum estrogen level,
deep breathing showed significant (p<0.05) positive correlation in follicular and luteal phase and
valsalva showed significant positive correlation during luteal phase. Conclusion: The results this
study suggest that estrogen has got positive influence on parasympathetic nerve function which
support cardioprotective role of estrogen in premenopausal females.
