The annual oviductal cycle of the American alligator, Alligator mississippiensis, is described using light and electron microscopy. Previous work done by Palmer and Guillette ([1992] Biol Reprod 46:39-47) shed some light on the reproductive morphology of the female alligator oviduct; however, their study was limited and did not report details relating to variation across the reproductive season...

Fertilization in a large number of animals occurs in a specific region of the female genital tract called the oviduct (uterine tube or Fallopian tube), which adjoins into the uterus and is located close to the ovary (Figures 1 and 2). The oviduct is a complex fibromuscular conduct with several layers comprising the mucosa, muscular layer, and a connective serosa. The size of these different lay...

The condition of tubal ectopic pregnancy is presented from diverse points of view, bringing out physiological explanations for its occurrence in primates and striking absence in other mammals. Part of the flexibility underlying ectopic pregnancy in humans stems from the absence of a uterine luteolytic mechanism, enabling early embryonic development in the Fallopian tube without compromising fun...

BACKGROUND Retroperitoneal ectopic pregnancy (REP) is an extremely rare type of ectopic pregnancy, with a total of less than 20 cases reported in the English literature. However, failure to recognize REP may result in severe consequences. CASE PRESENTATION We report a case of 32-year-old woman with REP. She had amenorrhea, left lower abdominal pain, but no vaginal bleeding. Her urine human ch...

background: abnormal uterine bleeding is a common presentation of uterine abnormalities among premenopausal and postmenopausal women. objective: to evaluate and compare the diagnostic accuracy of saline contrast sonohysterography and hysteroscopy for detecting the cause of abnormal uterine bleeding. materials and methods: a total of 65 women with abnormal uterine bleeding were enrolled in this ...

INTRODUCTION Fallopian tube carcinoma is a rare gynecological malignancy with low accuracy detection preoperatively. The symptoms are unspecific and imaging can be misleading. Since it was first described in 1847, there have been only a little over 2000 case reports. CASE PRESENTATION This case report describes a 66-year-old Caucasian woman who presented with progressive diffuse abdominal pai...

Aim to determine the age-related morphological features of isthmus fallopian tubes parous elderly and senile women in comparison with early adulthood.
 Material methods. For study, 79 were divided into 3 groups: Group I included 26 adulthood (aged from 22 35), II 28 57 74), III 25 75 88). The histological, micrometric statistical methods used study. preparations stained hematoxylin eosin. ...

In mammalian species there are significant physiological responses of the female reproductive tract to deposition sperm. These particularly notable in where sperm deposited directly into uterus, and function both facilitate transport reservoir, eliminate introduced contaminants. bitch, vagina rapidly transported through open cervix. Sperm then distributed around uterus by uterine contractions s...
