Sexually mature male Mongolian gerbils, Meriones unguiculatus, from known intra-uterine positions were each paired with a succession of nulliparous females. Those males that had matured in intra-uterine positions adjacent to two males (2M males) sired an average of 28% more young than did those males that had matured in intra-uterine positions between two females (2F males). In a second experim...

INTRODUCTION The levonorgestrel-releasing intra-uterine device (Mirena(R)) is an effective, long term form of contraception that leads to a significant reduction of menstrual bleeding among majority of women. However, irregular bleeding is quite common in initial Mirena(R) users and may thereby mask underlying cervical pathology. CASE PRESENTATION Two women with cervical cancer and a Mirena(R...

The reproductive biology of Dromiciops gliroides is described from five females collected during spring (October, December 1984) in southern continental Chile. Developmental morphology of intra-uterine embryos (October litters) was examined by microscopic analysis and compared with morphological attributes of 8 pouched young (December litters). Intra-uterine embryos demonstrate ontogenetic feat...

A 26-year-old patient presented at the emergency department because of uterine bleeding for the previous 3 days. She had undergone voluntary termination of pregnancy by curettage 2 months before. Upon clinical examination, metrorrhagia was moderate, with heart rate: 90/min, blood pressure: 110/80 mmHg and temperature: 36.9°C. Intra-vaginal ultrasound examination showed a heterogeneous intra-ute...

Although premature separation of normally implanted placenta is considered the most serious complication of pregnancy, knowledge of uterine behaviour during this con­dition is meager, on the basis of electronic recording of intra-uterine pressure two type of contraction pattern has been identified.  In type I uterine tonus has values below 30mmHg  with a frequency of 4-9 contractions per 10 m...

INTRODUCTION Pelvic actinomycosis constitutes 3% of all human actinomycosis infections. It is usually insidious, and is often mistaken for other conditions such as diverticulitis, abscesses, inflammatory bowel disease and malignant tumors, presenting a diagnostic challenge pre-operatively; it is identified post-operatively in most cases. Here we present a case that presented as pelvic malignanc...

home uterine activity monitoring (huam) has demonstrated to be of great value for preventing preterm labor in recent years. in this research, a low cost monitoring device for non-invasive monitoring of the uterine activity in pregnant women is presented. the new device has been designed based on an inductive colpitz oscillator and vertical displacement of a ferrite core in a coil. the resulting...
