Microfluidic Intracytoplasmic Sperm Injection (MICSI): A Novel Platform for Sperm Isolation, Selection, and Injection Into Oocytes

Andrology, EarlyView.
ABSTRACT Background Infertility is a pressing global health concern, affecting one in six couples worldwide. The failure rate for assisted reproductive technologies (ART) cycles remains at approximately 78%, with limited improvements often attributed to a lack of technological innovation.

Boosting Male Fertility: The Impact of Gonadotropin Therapy on Hypogonadotropic Hypogonadism—A Systematic Review and Meta‐Analysis

Andrology, EarlyView.
ABSTRACT Background Male hypogonadotropic hypogonadism typically presents with azoospermia and is one of the few causes of infertility amenable to a medical intervention. Gonadotropin therapy offers a chance to restore spermatogenesis and fertility in these individuals.

Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

Andrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Sperm Retrieval in Non-Azoospermic Patients with Intact Ejaculation: A Narrative Review [PDF]

International Journal of Fertility and Sterility
Although existing research on sperm retrieval predominantly focuses on azoospermic patients, assisted reproductive technology(ART) candidates without azoospermia may still face challenges during oocyte retrieval.

Limited Clinical Impact of Androgen Receptor Repeat Length (CAG and GGC) in Klinefelter Syndrome: A Multivariable Analysis

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS) is characterized by marked phenotypic heterogeneity that might be influenced by genetic modifiers, including androgen receptor (AR) repeat length (CAGn and GGCn). The clinical relevance of these repeat lengths in patients with KS before testosterone replacement therapy (TRT) remains unclear.
