Development of a risk model for low oocyte retrieval in first-cycle IVF patients with diminished ovarian reserve: a retrospective single-center study
Low oocyte retrieval (LOR), defined as oocytes retrieved from

Maternal exposure to cyclophosphamide during prepubertal life does not affect the cryosusceptibility of in vitro derived mouse embryos
Prepubertal exposure to gonadotoxic chemotherapy, such as cyclophosphamide (CY), poses a significant risk to long-term fertility by depleting ovarian reserve and impairing oocyte quality. Such treatments are commonly administered to young girls with cancer, and when these individuals later seek…

Optimizing fixed-time laparoscopic artificial insemination in the jaguar
The jaguar faces significant threats to survival from habitat fragmentation/loss and poaching. Conservation efforts include maintaining ex situ populations in zoos, but breeding success remains limited, necessitating the development of assisted reproductive technologies. This study aimed to…

Advantages and disadvantages of peri-abortion ultrasonography
Ultrasonography remains an important component of abortion care, as it does in early pregnancy in general. We propose that selective use of ultrasonography, in line with World Health Organization recommendations, allows clinicians and services to maximise the advantages of peri-abortion ultrasound…

Effect of freezing and cryostorage on follicular fluid vitamin D levels
In the studies assessing the relationship between vitamin D levels and pregnancy outcomes in in vitro fertilization, doctors sometimes collected and froze the follicular fluid (fluid around eggs in a woman’s ovaries) so they can test it later for research. This study aimed to find out if freezing…

Toll-like receptors 7 and 8 can be targeted to enrich Y-chromosome sperm in the domestic dog
An effective method of sperm sex separation for use in the domestic dog is desirable for the breeding of working dogs and for the study of sex-linked diseases in research models. Previous reports identified the X-linked Toll-like receptors 7 and 8 (TLR7/8) as useful targets for immunological sperm…

An early LH surge may jeopardize ART outcomes of patients with PCOS and its predictive models
This study aimed to investigate whether an early LH surge during controlled ovarian stimulation (COS) affects pregnancy outcomes in patients with polycystic ovary syndrome (PCOS) undergoing assisted reproductive technology (ART) and to explore methods for identifying high-risk patients for early…

Oral administration of rumen-protected choline to ewes during the periconceptional period skews the sex ratio of lambs
Feeding rumen-protected choline (RPC) to beef cows during the periconceptional period has been reported to alter embryonic development to reduce weaning weight of the resultant calves. Here, it was tested whether oral administration of RPC to ewes during the periconceptional period programs…

The value of a non-invasive bladder sensitivity paradigm in chronic pelvic pain
We explore bladder sensitivity profiles in females with chronic pelvic pain, using a non-invasive bladder sensitivity paradigm. We aim to determine how profiles differ between groups defined by symptoms; groups defined by diagnoses; and understanding how bladder sensitivity relates to clinical…

Establishment and application of a prediction model for blastocyst formation rate and delivery outcome in human assisted reproductive technology
With the gradual emergence of population issues and the increasing incidence of infertility, the role of assisted reproductive technology (ART) is becoming increasingly important. Accurately, objectively, and comprehensively assessing the blastocyst formation rate and predicting delivery outcomes…

Phoenixin-14 ameliorates ovarian morphology in a DHEA-induced rat model of PCOS
Polycystic ovary syndrome (PCOS) is a complex reproductive–endocrine disorder characterized by impaired folliculogenesis, anovulation, and hormonal imbalance. While PNX-14 is known as a hypothalamic peptide that modulates GnRH signaling, emerging evidence indicates its local ovarian expression…

Declining semen quality in North Africa: from 2019 to 2024: retrospective multicentric study of 21,585 patients
Recent evidence suggests a global decline in semen quality, raising significant concerns about male reproductive health. Data from North Africa are limited, and the region faces unique environmental and lifestyle challenges. In addition, the COVID-19 pandemic may have caused transient or lasting…

Factors and pathways influencing fertility anxiety in reproductive-age male cancer patients: a stress process theory perspective
Background: Fertility concerns among cancer patients of reproductive age are widespread and persist for 5–10 years from diagnosis through treatment, with effects that often surpass those associated with the cancer itself. Unlike female patients who exhibit stronger self-disclosure tendencies, male…

Heat shock suppresses the innate immune response of bovine endometrial epithelial cells
With rising global temperatures, it is imperative to determine the impact of heat stress on the physiology of food-producing animals. Dairy cows are susceptible to uterine diseases that reduce fertility. Immune function is important in the development and progression of disease; however, the effect…

Multivariate model predicts immune imbalance in recurrent pregnancy loss and recurrent implantation failure
Recurrent pregnancy loss (RPL) and recurrent implantation failure (RIF) are thought to arise from distinct yet partially overlapping causes, with a substantial number of cases associated with immune system alterations. We hypothesized that a peripheral blood signature integrating natural killer…

Effects of prolonged embryo cryopreservation after fertility treatment in Denmark
This retrospective cohort study examined the effects of the Danish legislative amendment extending the permitted duration of embryo cryopreservation from five years until the woman reaches 46 years on frozen embryo transfer (FET) during assisted reproductive technology. The number of embryos…

Therapeutic benefits of gonadotropins in male hypogonadotropic hypogonadism: a focus on spermatogenesis and fertility
Male hypogonadotropic hypogonadism is characterized by deficient secretion of luteinizing hormone and follicle-stimulating hormone, leading to low testosterone levels, impaired spermatogenesis, and often infertility. Treatment aims to normalize testosterone and induce spermatogenesis, with…

A pilot study on the use of transcutaneous auricular vagus nerve stimulation to relieve dysmenorrhea in patients with adenomyosis and endometriosis
Adenomyosis and endometriosis are two sister diseases that cause menstrual pain and other symptoms. We have previously reported that patients with these conditions have a less active ‘calm-and-rest’ system and a more active ‘stress-and-alert’ system. Other studies have shown that a gentle…

Excess female adrenal androgen secretion is a consequence of in utero androgenic excess in sheep
Excess androgenic steroid exposure during development in female sheep alters metabolic and reproductive function in postnatal life, with phenotypes reminiscent of health-relevant aspects of Polyendocrine Metabolic Ovarian Syndrome (PMOS) in women. We hypothesised that altered steroid exposure…
