Massive hemoperitoneum secondary to ruptured corpus luteum is a rare but serious and life-threatening complication for women with congenital bleeding disorders and may lead to surgical interventions and even oophorectomy. Congenital afibrinogenemia is a rare inherited coagulation disorder. As it can be asymptomatic, its clinical manifestations vary from minimal tendency of bleeding to life-threatening bleedings. Intraabdominal bleeding due to ovulation is very rare in these patients and only a few cases of corpus luteum rupture and hemoperitoneum in afibrinogenemic patients have been described. We report on a 28-year-old woman with congenital afibrinogenemia with recurrent massive intraabdominal bleeding due to ovulation as the presenting clinical sign. The first episode was managed with fresh frozen plasma, cryoprecipitate and blood transfusions; exploratory laparotomy and excision of the ruptured follicle was performed at the second episode; the third episode was managed with fresh frozen plasma, cryoprecipitate and blood transfusions; exploratory laparotomy and right salphingooopherectomy was performed at the fourth episode; fifth episode was managed with fresh frozen plasma, cryoprecipitate and blood transfusions. Conservative management is crucial for patients with congenital bleeding disorders. These case demonstrate that preservation of ovarian function is possible with a conservative approach and recurrent episodes may be prevented by suppression of ovulation.

Von Willebrand's disease (vWD) is an inherited coagulopathy. In women, this condition can present as periovulatory intra-abdominal bleeding or bleeding from the corpus luteum. A diagnosed case of vWD presented as an emergency with nausea, acute abdominal pain and dizziness.

The objective of this study was to compare the fertility of diestrous mares with a follicle ≥ 30 mm in diameter treated with prostaglandin F2α (PGF) (PGF group) or left untreated for 7 days (SP group). Standardbred mares (n = 46) were assigned randomly to the SP (n = 23) and PGF groups (n = 23) when they were identified with a corpus luteum (CL) of unknown age and a follicle ≥ 30 mm in diameter (Day 0). The most frequent outcome in the PGF group was estrus and ovulation of the dominant follicle (74 %), while the outcomes of the SP mares 7 days after Day 0 were more variable: estrus and follicle regression (30 %), diestrous ovulation (22 %) and diestrus along with follicle regression (26 %) of the dominant follicles.

In this chapter, we explore the multifaceted roles of extracellular vesicles (EVs) in ovarian biology, focusing on their contributions to folliculogenesis, oocyte competence, corpus luteum function, and immune response regulation. EVs, particularly those derived from follicular fluid (ffEVs), are crucial mediators of cell-to-cell communication within the ovarian follicle, influencing processes such as meiotic progression, stress response, and hormonal regulation. We review preexisting literature, highlighting key findings on the molecular cargo of EVs, such as miRNAs and proteins, and their involvement in regulating the function of the follicle cells.

Ovaries are of paramount importance in reproduction as they produce female gametes through a complex developmental process known as folliculogenesis. In the prospect of better understanding the mechanisms of folliculogenesis and of developing novel pharmacological approaches to control it, it is important to accurately and quantitatively assess the later stages of ovarian folliculogenesis (i.e.

Background: Senility influences fertility in women and companion animals, especially horses.
Aim: This study aimed to investigate the effect of aging in horses on the daily changes in the dominant follicle (DF) dynamics and hemodynamics, antimüllerian hormone (AMH), enzymes, antioxidants, and ovarian hormones during the estrous cycle.
Methods: Ovaries of old mares ( = 5, age >20 years) and young native mares ( = 6, age <10 years) were scanned during 6 different estrous cycles from March 2022 to August 2023 with Doppler ultrasound.
