زمينه: مرزه تابستاني (Satureja hortensis L.) از خانواده Lamiaceae و داراي اثرات آنتي اكسيداني، ضدالتهابي و ضدآپوپتوتيك است. هدف از مطالعه حاضر بررسي اثر عصاره هيدروالكلي برگ مرزه تابستاني بر سطح LH، FSH و تستوسترون سرم در موش هاي صحرايي نر مواجه شده با استرس بي حركتي مزمن مي باشد.
مواد و روش ها: اين تحقيق به صورت تجربي انجام گرفت. 48 سر رت نر بالغ نژاد ويستار به 6گروه شامل 1) كنترل، 2) استرس، 3) مرزه 200، 4) مرزه400، 5) استرس- مرزه 200 و 6) استرس-مرزه 400 تقسيم شدند. گروه هاي 2و 5 و 6 هر روز 6 ساعت به مدت 21روز متوالي در مقيدكننده قرار گرفتند و گروههاي 3و4و5و6 عصاره هيدروالكلي مرزه را با دوزهاي mg/kg/BW200 و 400 به صورت گاواژ و به مدت 21روز دريافت نمودند. در پايان دوره سطح LH، FSH و تستوسترون سرم اندازه گيري شد.
نتايج: بي حركتي مزمن موجب كاهش معني دار غلظت (LH (p<0.01), FSH (p<0.01, و تستوسترون (0/001

Background: Summer savory- Satureja hortensis L. is from Lamiaceae family and has
antioxidant, anti-inflammatory, anti-apoptotic properties. The purpose of this study is to
investigate the effect of hydro-alcoholic extract of Summer Savory leaves on the level of
LH, FSH and testosterone in male rats exposed to chronic immobilization stress.
Material and Methods: This study was conducted experimentally. 48 adult male Wistar
rats were divided into 6 groups including: Control, Stress, Savory 200, Savory 400,
Stress-Savory 200, and Stress-Savory 400. Groups 2, 5, and 6 were placed into restrainer
for 6hours per day during 21 consecutive days and groups 3, 4, 5, and 6 were gavaged by
hydro-alcoholic extract of Summer Savory with different doses of 200,400mg/kg during
21consecutive days. The level of LH, FSH and testosterone were measured by the end of
period.
Results: Chronic Immobilization caused significant decrease in serum concentrations of
LH (p<0.01), FSH (p<0.01), and testosterone (p<0.001) in stress group compared with the
control group and taking both doses of plant extracts inhibited the above effect.
Conclusion: It is concluded that the Satureja hortensis extract may stimulates the
hypothalamic-pituitary-gonadal axis and prevents stress-induced reproductive damages.
