Infertility Affection of uterus

Acute Puerperal Metritis


It occur in all species. occurs within the first 10 days after parturition. Acute onset. Contamination of reproductive tract at parturition and often it follows complicated parturition.
Acute Puerperal Metritis: Also called postpartum metritis, toxic puerperal metritis or acute septic metritis


Predisposing factors for acute metritis: 1. Uterine damages: stillbirth, dystocia, twins, cesarean section, retained placenta, delayed uterine involution. 2. Metabolic conditions: milk fever, ketosis, left displaced abomasum.

Clinical signs:

Depressed, febrile, and inappetent. Uterine discharge is reddish-brown, fetid and watery (cows) but may not be observed in other species. elevated body temperature. Milk production is diminished The palpation of the uterus per rectum reveals an enlarged and flaccid uterus. Acute puerperal metritis responds well to systemic antimicrobial therapy - usually penicillin


Treatment: An ideal treatment of metritis should eliminate bacteria from the uterine cavity and the subendometrial layers without inhibiting uterine defense mechanisms. It should provide optimal reproductive performance in the current lactation, and not cause economic losses by milk withdrawl.


The best method for the therapy of acute metritis was using a systemic antibiotic treatment. The effective treatment was achieved by administration of penicillin, oxytetracycline, systemically.


Pyometra


It is on of chronic metritis. It is characterized by accumulation of pus or mucopurulent in the uterus. The corpus luteum is retained and absence of oestrus.
Pyometra:

Abnormal parturition. Uterine infection. Abnormal uterine involution in some condition such as: abortion, premature birth, dystocia, retained placenta and septic metritis.
Pyometra: The condition usually occur following:


Pyometra may be exists for 60-90 days or more after parturition with a failure of estrus. Some time pyometra occur after service and this condition usually associated with early embryonic death.
Pyometra:

Failure of estrus. When the cervix is opened, the pus is observed when the cow lies down, at urination or at defecation. On rectal examination the uterine wall is usually thicken, flaccid and atonic.

Firstly the corpus luteum must be removing. If the new estrus cycle is begin, the cervix will dilate, the uterus will contract and the pus will be evacuated. PGF2α.Estradiol + Oxytocin. Pyometra: Treatment:

Mucometra&Hydrometra

Both conditions are occur due to accumulation of mucin in the uterus which may vary from a watery fluid to a simisolid. These cases were seen as a secondary result of cystic ovaries.
Mucometra & Hydrometra:
