Abstract

The present study carried out on (36) mature female Wister rats about (65-70) days old divided into (6) groups included (6) female which not given any treatment as control group, other (30) female treated with progesterone (20 mg/kg, s.c) daily for 7 days , after 24hrs. injected with PMSG (150 IU/kg, i.p) and after 48hrs. injected LH (75 IU/kg, i.p) and divided for (5) groups within 14-15hrs. equally, (T1) put with mature male rat (1:2) and isolated after 48hrs. for natural mating, (T2) given alkaline solution in vagina for two days during first and second day from natural mating with mature male rat and removed after 48hrs., (T3) treated with acidic solution in vagina for two days during first and second day from natural mating with mature male rat and separated after 48hrs., (T4) inseminated artificially with upper layer of solution prepared from tail of epididymis and put with castrated male rat for 48hrs. after injected with oxytocin (10 m IU/g, i.p), (T5)inseminated artificially with a lower layer of a solution prepared from a tail of epididymis and put with a castrated male for 48hrs. after injection of oxytocin (10 m IU/g, i.p). The results revealedT4& T2 recorded high ratio of newly born males (71.429%&63.415%), while (C, T1, T3& T5) were (28.571, 30.952, 23.810 and 25%) respectively. While the high ratio of newly born females rate recorded in (T3&T5) were (76.190% and75%), and in (C, T1, T2,&T4) recorded (71.429, 69.048, 36.585 and 28.571%) respectively. The pregnancy rate was 100% in all hormonally treated groups compared with the control group and groups inseminated artificially which recorded 50%. Addition to that, the results showed highly significant variance (P≤0.01) in newly born numbers with a mathematic decrease in body weights of hormonally treated groups.

Abstract

The current study was conducted in the center of Al-Diwaniya city, Al-Qadisiya province in Iraq during a period of one year from (15/1/2012 to 15/1/2013) divided according to the sexual activity of males into three periods: the 1st period extended from mid of January to February, the 2nd period from February to November, and the 3rd period from November to mid of January. During these entire periods forty seven male local breed cats, (ten for each of the 1st and 3rd periods, while the other twenty seven were included in the 2nd period). All males were monitoring during the night and early morning to evaluate the behaviors, and then hunted to evaluate hormonal and histological changes in the male genital system. The results of behavioral study during the 1st period revealed that the male showed caterwaul sound, urination and following of the females with foreplay but without mating; in the 2nd period the same notes were observed with a huge desire to mating and obligating females for mating; the behaviors in the 3rd period were as the same of the 1st period. The ratios of studied periods during year were (4.16%, 75% and 20.84%) respectively. The results of the hormonal assay revealed that the testosterone levels were (0.42, 1.31 and 0.35 ng/ml) for the three periods of study respectively, while the LH concentrations were (1.31, 4.86 and 1.23 ng/ml) respectively. The histological study of testis showed that the seminiferous tubules characterized by very active vacuolated Sertoli cells filled with secretions with presence of all developmental stages of spermatogenesis, while the 1st and 3rd period characterized by thickening of connective tissue and peritubular tissue as well as not all developmental stages of spermatogenesis.

أجريت الدراسة الحالية في مركز مدينة الديوانية على مدار سنة كاملة للفترة من 15/1/2012 إلى 15/1/2013 . قسمت فترات الدراسة حسب النشاط الجنسي للذكور إلى ثلاث فترات: الفترة الأولى والتي امتدت من منتصف كانون الثاني وحتى شباط ، الفترة الثانية من شباط إلى تشرين الثاني والفترة الثالثة من تشرين الأول إلى منتصف كانون الثاني. اشتملت الدراسة على سبعة وأربعين ذكرا من القطط (السلالة المحلية)، بواقع عشرة ذكور لكل من الفترتين الأولى والثالثة وسبعة وعشرون للفترة الثانية. تم مراقبة الذكور لرصد نشاطها خلال فترة الليل وفي الصباح الباكر لتقييم التغيرات السلوكية ومن ثم اصطيدت لدراسة التغيرات الهرمونية والنسجية في الجهاز التناسلي الذكري. أظهرت نتائج رصد سلوك الذكور خلال الفترة الأولى: أصوات المواء ، و التبول ومن ثم مداعبة الإناث ولكن من دون التزاوج ، بينما لوحظ نفس السلوك في الفترة الثانية على الذكور ولكن مع رغبة جامحة للجماع وإرغام الإناث على التزاوج وكان السلوك خلال الفترة الثالثة مشابها للسلوك خلال الفترة الأولى. النسبة المئوية لفترات الدراسة خلال السنة كانت (4.16%،75%و20.84%) على التوالي. و على مستوى الفحص الهرموني كان مستوى هرمون التستوستيرون 0.42 ng/ml ، 1.31 ng/ml و 0.35 ng/ml في الفترات الثلاثة على التوالي ، في حين كانت تراكيز الهرمون اللوتيني 1.31ng/ml ، 4.86ng/ml و 1.23 ng/ml على التوالي. كما أظهرت الدراسة النسيجية للخصى خلال الفترة الثانية من الدراسة أن النبيبات المنوية تميزت بنشاط واضح من خلال تميز خلايا سرتولي بكبر حجمها وامتلائها بالإفرازات مع وجود جميع مراحل نمو الحيوانات المنوية ، في حين تميزت الدراسة الشكلية لنسيج الخصية خلال الفترة الأولى والثالثة بسمك النبيبات المنوية حيث لوحظ سمك النسيج الخلالي الضام وكذلك عدم اكتمال في مراحل تطور الحيوانات المنوية.
