For men with obstructive azoospermia, several surgical sperm retrieval techniques can facilitate conception with assisted reproductive technology. The evolution of both percutaneous and open approaches to sperm retrieval has been affected by technological innovations, including the surgical microscope, in vitro fertilization, and intracytoplasmic sperm injection. Further modifications to these procedures are designed to minimize patient morbidity and increase the quality and quantity of sperm samples. Innovative technologies promise to further ameliorate outcomes by selecting the highest quality sperm. Although various approaches to surgical sperm retrieval are now well established, several advancements in sperm selection and optimization are being developed.

Background: Sperm extraction by Microscopic Testicular Sperm Extraction (microTESE) has become the standard of care for sperm retrieval (SR) in men with non-obstructive azoospermia (NOA) but is costly and has a 40-50% chance of failure. Fine needle aspiration mapping (FNAM) can be performed prior to microTESE as a predictor of success to reduce the likelihood of failure to retrieve sperm but there is limited evidence that directly compares these methods. The objective of this study was to compare success rate of SR, pregnancy, and live birth rates in men who underwent upfront microTESE versus FNAM.

Success Rates of Assisted Reproduction for Men With Cystic Fibrosis.

Pediatr Pulmonol

Department of Respiratory Medicine, Manchester Adult Cystic Fibrosis Centre, North West Lung Centre, Wythenshawe Hospital, Manchester University NHS Foundation Trust, Manchester, UK.

Background: The vast majority of men with CF (mwCF) are infertile. Improvements in assisted reproductive technology (ART) have made it possible for these patients to become biological fathers.

Methods: Data were examined for all male CF patients attending a large adult CF center over a 23-year period.

Objectives: To determine if routine pre-vasectomy sperm cryopreservation is more cost-effective than fertility restoration for patients who desire additional children following vasectomy?

Methods: A scoping review was performed to collect published data regarding efficacy and outcomes of cryopreservation, vasectomy reversal, surgical sperm retrieval, and assisted reproductive technologies (ART). Cost data were collected from US-based facilities performing cryopreservation and andrology clinical care. A cost-effectiveness model was generated using TreeAge Pro cost-effectiveness modeling software with three different variations representing a balanced scenario with median expected parameter values, a scenario with assumptions/variables favoring pre-vasectomy cryopreservation, and a scenario favoring fertility restoration.

Division of Reproductive Medicine, Department of Obstetrics and Gynecology, Taipei Medical University Hospital, Taipei, Taiwan; Department of Obstetrics and Gynecology, School of Medicine, College of Medicine, Taipei Medical University, Taipei, Taiwan. Electronic address:

The objective of this review is to evaluate the contributions of Artificial Intelligence (AI) to Assisted Reproductive Technologies (ART), focusing on its role in enhancing the processes and outcomes of fertility treatments. This study analyzed 48 relevant articles to assess the impact of AI on various aspects of ART, including treatment efficacy, process optimization, and outcome prediction. The effectiveness of different machine learning paradigms-supervised, unsupervised, and reinforcement learning-in improving ART-related procedures was particularly examined.

Background: Gonadotropin-releasing hormone agonists (GnRHa) are commonly used in assisted reproduction technology (ART) cycles to prevent a luteinising hormone (LH) surge during controlled ovarian hyperstimulation (COH) prior to planned oocyte retrieval, thus optimising the chances of live birth. We compared the benefits and risks of the different GnRHa protocols used.

Objectives: To evaluate the effectiveness and safety of different GnRHa protocols used as adjuncts to COH in women undergoing ART.
