Assisted reproduction technologies and ovulation induction for treatment of infertility continue to cause high order multiple gestations. Increased perinatal morbidity and mortality, as well as maternal morbidity, may complicate these pregnancies. Selective fetal reduction, an acceptable therapeutic approach in these cases, is usually performed at or after the ninth week of gestation, with KCl ...

In pea, high temperatures during reproductive development lead to severe yield loss. Although the ovule is seed precursor, studies elucidating effect of heat on this plant structure are scarce. We investigated impact in field and growth chamber ovules 4 days after open flower (4DOF) stage. Objectives were identify associations between ovaries performance, evaluate set abortion heat-treated plan...

This study tested the effectiveness of the framing effect and fear appeals to inform young people about the risks of multiple births and the option of selecting elective single-embryo transfer (eSET). A non-patient student sample (age (mean±SD) 23±5.5 years; n=321) were randomly allocated to one of seven groups: (1) framing effect: (1a) gain and (1b) loss frame; (2) fear appeal: (2a) high, (2b)...

The effect of boar exposure during artificial insemination (AI) on semen backflow, fertilization, and embryo quality was evaluated. Gilts (approximately 170 d) were induced into estrus with PG600, and ovulation was synchronized using hCG 72 h later. Estrus detection was initiated after PG600 and continued at 12-h intervals. At estrus, gilts were allotted to receive boar exposure (BE, n = 20) or...

Abstract Study question Our aim was to analyse the embryo-maternal-interaction, focusing on insulin/IGF-system and lipid metabolism day 6 of pregnancy in reproductive young old rabbits. Summary answer Advanced maternal age has a decisive effect embryonic insulin/IGF-signalling metabolism, leading higher embryo loss already during preimplantation period. What is known The potential women decline...

Chronic endometritis (CE) is an infectious disease of the uterine lining, which characterized by endometrial stromal plasmacyte (ESPC) infiltration. CE often seen in infertile women with a history repeated implantation failure (RIF) following vitro fertilization-embryo transfer program, recurrent pregnancy loss, and unknown etiology. Oral antibiotic agents, such as doxycycline, metronidazole, c...
