Basal body temperature, quantitative changes in vaginal smears and plasma concentrations of progesterone were measured during a number of oestrous cycles in Tasmanian bettongs (Bettongia gaimardi). These methods of monitoring the reproductive cycle were compared in an attempt to find a technique that allowed non-stressful assessment of the reproductive condition of the bettongs. Telemetric meas...

BACKGROUND Sample sizes for obstetrical trials are often based on the opinion of investigators about clinically important effect size. We surveyed Canadian obstetricians to investigate clinically important effect sizes required before introducing new treatments into practice to prevent preterm birth. METHODS Questionnaires were mailed to practicing obstetricians, asking the magnitude of pregn...

Pyogenic granuloma is a benign vascular tumor that may affect the gastrointestinal tract. This report describes a rare case of sigmoid-colon pyogenic granuloma in a 4-month-old boy causing intussusception. Resection and anastomosis were curative. The mother had history of high dose of progesterone exposure during initial weeks of conception for vaginal bleeding. This may point towards etiology ...

Ectopic pregnancy (EP) and miscarriage are important differential diagnosis of first trimester vaginal bleeding. In first trimester, serum progesterone value can be 5-20 ng/ml in EP and miscarriage. Since delay in diagnosis of EP could have high mortality and morbidity, the aim of this study was comparison of serum progesterone value in EP and miscarriage in order to differentiate these conditi...

Electrical resistance (ohms) of mucus were analyzed in 20 postpartum Holstein cows by use of a probe inserted into the anterior vagina every other day for 30 days. Composite milk samples were taken on the same day, and progesterone was determined by radioimmunoassay. Cows were observed twice daily for standing estrus and reproductive organs palpated weekly per rectum (rectal palpation). Fifteen...

BACKGROUND Threatened abortion is a common complication of pregnancy. In order to prevent miscarriage in the cases with threatened abortion, this study was conducted to determine whether progesterone suppository is effective in allowing pregnancy to proceed beyond week 20 in women with threatened abortion. METHODS This single-blind clinical trial study was done on 60 pregnant women with threa...

Female rats were made persistent-estrous and anovulatory by giving a single injection of 1.25 mg of testosterone propionate 4 days after birth. The rats were ovariectomized when adult and given 7 daily injections of progesterone plus estradiol in amounts sufficient to condition the uteri fbr fbrmation of deciduomata in response to trauma. The administration of the hormones was commenced on the ...

BACKGROUND Colonization of the female lower genital tract with Lactobacillus provides protection against STIs and adverse pregnancy outcomes. Growth of genital Lactobacillus is postulated to depend on epithelial cell-produced glycogen. However, the amount of cell-free glycogen in genital fluid available for utilization by Lactobacillus is not known. METHODS Eighty-five genital fluid samples f...

OBJECTIVE To evaluate the effect of the addition of estradiol to luteal progesterone supplementation in GnRH antagonist cycles for infertile patients undergoing IVF/ICSI. METHODS One hundred and ten infertile patients, aged 28 to 39 years, were recruited for this prospective randomized study. They were randomly assigned to receive vaginal progesterone gel (Crinone) along with 4 mg estradiol v...

background while tocolytic therapy can halt the process of delivery, some patients return before the 37th week of pregnancy with recurrence of preterm labor signs. objectives this study was designed to evaluate the efficacy of progesterone in the prolonging of gestation and reduction of neonatal complications. material and methods in a clinical trial in 2010, 110 singleton pregnant women admitt...
