In 7 ewes during late pregnancy, peripheral plasma concentrations of oestrogens were correlated with uterine activity (P less than 0-01; r=+0-47). In myometrial tissue, the concentration of progesterone was similar to that in plasma; it rose to a plateau from Days 115 to 130 of pregnancy and then fell, but was still detectable during parturition. Myometrial oestrogen concentration was much higher than in plasma; from a peak at Days 100-115 it decreased, but rose sharply just before parturition.

Background Infertility affects a significant proportion of reproductive-age couples globally, with diverse causes. Diagnostic hystero-laparoscopy (DHL) is emerging as a preferred diagnostic tool for evaluating infertility, combining laparoscopy and hysteroscopy for comprehensive assessment. Objective The primary objective of this prospective study was to evaluate the diagnostic accuracy and clinical utility of DHL in identifying the causes of infertility in women.

Introduction: The future of training in second trimester surgical abortions with dilation and evacuation (D&E) procedures faces ongoing legal and political scrutiny; thus, adjuncts to standard clinical experiences are exceedingly important. We sought to build medical trainees' surgical familiarity with D&Es using a realistic simulation model.
Methods: The simulation began with an instructional video reviewing accessible and affordable materials used to build the fetal model (vaginal swabs, styrofoam ball, and putty) and the uterine model (collapsible water bottle).

Background: Placental syndrome, mainly composed of preeclampsia and fetal growth restriction, has an impact on the health of mother and baby dyads. While impaired placentation is central to their pathophysiology, the underlying molecular mechanisms remain incompletely understood. This study investigates the association between placental syndrome and metabolic alterations in 1-deoxysphingolipids (1-deoxySLs) and polyamines, along with their regulatory enzymes.

The aim was to study the effect of long-acting analogue of oxytocin (Carbetocin) on cervical collagenolysis of MAP-eCG synchronized ewes. At the expected time of artificial insemination, five ewes were slaughtered (n = 5) and their cervical explants (100-200 mg) were incubated during 12 h with MEM supplemented with 0, 8, 16, 32 and 64 ng/mL of Cb. Activities of activated and latent forms of matrix metalloproteinases-2 and - 9 (MMP-2 and MMP-9, respectively) in the supernatant were determined by a SDS-PAGE zymography and prostaglandin E2 concentration by immunoassay.

This case highlights the critical role of early radiological screening by ultrasound in identifying uterine anomalies. In this report, we discuss a 39-year-old pregnant woman, gravida 4 para 3, and her fetus at gestational age 18 weeks. The patient was referred to the Obstetrics and Gynecology Emergency Department at Qatif Central Hospital, Saudi Arabia, from a private hospital due to an ultrasound study indicating a possible ectopic pregnancy with an abdominal fetal location.
