Objective: To compare pregnancy outcomes and serum progesterone levels between women who took sublingual (SL) progesterone lozenges versus intramuscular (IM) progesterone-in-oil for endometrial preparation and luteal support in programmed frozen embryo transfer (pFET) cycles.
Design: Retrospective cohort study.
Subjects: All patients who underwent pFET of a single euploid good-quality blastocyst between January 2018 and April 2023 at a single fertility center.

Objective: To determine the diagnostic performance and clinical utility of the M4 prediction model and the NICE algorithm managing women with pregnancy of unknown location (PUL).
Design: The study has a superiority design regarding specificity for non-ectopic pregnancy for M4, given that the primary outcome of sensitivity for ectopic pregnancy (EP) is non-inferior in comparison with the NICE algorithm.
Setting: Emergency gynaecology units in Sweden.

Department of Clinical Research, University of San Luis Potosí, San Luis Potosí, MEX.
Background: In large-scale molecular studies, a protocol that generates high yields and quality DNA for future polymerase chain reaction (PCR) assays is needed. The collection of buccal cells by cytobrush may represent an efficient, noninvasive, and inexpensive method for obtaining genetic material from school populations. The aim of this study was to develop a method to obtain genomic DNA from buccal cells of schoolchildren, and the DNA was extracted immediately after collecting the buccal cell samples and after storing the samples for 8 months at -20 °C to establish the feasibility of the method for epidemiological studies.

The current study investigated the effect of a single administration of human chorionic gonadotropin hormone (hCG) and its nanoparticles (NPs) on testicular hemodynamics using Doppler ultrasonography, testicular volume, testicular echotexture (PIX), and circulating testosterone and nitric oxide (NO) in pubescent goat bucks during summer months. Fifteen Baladi goats were divided into three groups (5 in each) and subjected to a single intramuscular administration of one ml of physiological saline ( control group), one ml containing 500 IU of hCG (hCG group) or one ml containing 125 IU of hCG NPs (hCG NPs group). Testicular hemodynamics assessment was done just before administration (0 h), and at 2, 4, 6, 24, and daily till 7 days after administration.

BACKGROUND Gestational trophoblastic diseases (GTDs) are a group of benign and malignant tumors that arise from placental tissue. Ectopic pregnancies most commonly occur within the fallopian tubes. The estimated incidence of ectopic gestational trophoblastic diseases (GTDs) is approximated at 1.
