The majority of women who freeze their eggs for non-medical or social reasons, commonly referred to as elective egg freezing (EEF), do not eventually utilize their frozen eggs. This would result in an accumulated surplus of unused frozen eggs in fertility clinics worldwide, which represents a promising source of donation to infertile women undergoing IVF treatment. Rigorous and comprehensive counseling is needed, because the process of donating one's unused surplus frozen eggs involves complex decision-making. Prospective EEF donors can be broadly categorized into those who have achieved motherhood and those who remained childless and have given up on motherhood aspirations. A two-step systematic counseling protocol is proposed. Firstly, it is imperative to verify and ensure that these women do not want to conceive any children with their surplus frozen eggs before proceeding with further counseling and signing of consent forms. Secondly, various motivating and dissuading factors in the donation of unused surplus frozen eggs should then be comprehensively discussed with egg freezers to facilitate informed decision-making. Key motivating factors for donation include reciprocity in wanting to share the joys of motherhood among egg freezers who already have children, goodwill to help others in need, and avoiding the wastage of surplus frozen eggs after expending so much money, time, and effort. Key dissuading factors include fear of accidental incest between natural and unknown donor-conceived offspring, as well as apprehension of unexpected future contact with unknown donor-conceived offspring due to either donor anonymity being abolished in their jurisdiction or widespread consumer DNA testing.

This study systematically investigated the effects of multiple freeze-thaw(F-T)cycles using four thawing methods on the foaming characteristics of egg white proteins and their regulatory mechanisms. The results indicated that the foaming capacity of air and water bath thawed samples increased with the number of F-T cycles. In contrast, vacuum thawing significantly reduced the foaming capacity, while ultrasonic thawing exhibited the optimal foaming capacity.

Parasitic diseases are associated with diverse clinical signs, and veterinary professionals must be familiar with the presentations of infections in a variety of hosts. As human activity introduces new and exotic host species, expanding our understanding of pathogen effects in new species becomes integral to effective surveillance, diagnosis, and treatment. This article presents the expansion of the known host range of the American liver fluke, Fascioloides magna, with the infection of a farmed impala (Aepyceros melampus) in Marion County, Florida, USA.

Background: For patients with recurrent serous borderline ovarian tumors (BOT) who have undergone unilateral salpingo-oophorectomy, there is a risk of reduced or even lost ovarian reserve after the second surgery; therefore, fertility preservation (FP) prior to re-operation in patients of childbearing age is challenging, and has attracted increasing attention. Here, we discuss the multidisciplinary whole-process management of a patient with recurrent serous BOT, from embryo cryopreservation (EC) before re-fertility-sparing surgery (re-FSS) to successful delivery.
Case Presentation: We describe the treatment of a 28-year-old married, nulliparous female with recurrent serous BOT who requested FP.

Background: With the advancements in fertility preservation technology, such as egg freezing, women could now preserve their gametes for potential future parenthood. It is important to explore how the needs of women are addressed and supported throughout the egg-freezing process. By investigating the experiences of research participants, we aimed to identify how reproductive rights are interpreted for egg-freezing applicants in Iranian infertility centers.

Abstract: People in low- and middle-income countries face many obstacles when trying to access fertility treatments. These challenges include high costs, the need for specialized medical facilities, and cultural beliefs that may discourage seeking help. This paper explores how artificial intelligence (AI) and automation could help overcome some of these barriers and make fertility treatments more widely available.
