Antioxidants, 2020 Spermatozoa capacitation is a complex process that requires specific ionic and energetic conditions to support biochemical alterations leading to motility hyperactivation. However, human sperm capacitation is still poorly understood.

Toward a Politics of (In)Fertility: Reproductive Debility in Africa
American Anthropologist, EarlyView.ABSTRACT Sub‐Saharan Africa has some of the highest estimated rates of infertility or involuntary childlessness in the world, leading epidemiologists to refer to parts of the region as the “infertility belt.” The medicalization of infertility and the situating of assisted reproductive technologies (ARTs) as the treatment for infertility have siphoned ...

Andrology, EarlyView.ABSTRACT Background Testicular germ cell tumours (TGCT) are the most common malignancies among young men and represent a major threat to reproductive health. Both the disease itself and oncological treatments, particularly chemotherapy, can compromise spermatogenesis and semen quality.

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 Adhesion Molecule 1 (SPAM1) Distribution in Selected Human Sperm by Hyaluronic Acid Test
Biomedicines, 2022 The failures of binding to the oocyte zona pellucida are commonly attributed to defects in the sperm recognition, adhesion, and fusion molecules. SPAM1 (sperm adhesion molecule 1) is a hyaluronidase implicated in the dispersion of the cumulus-oocyte ...

Improving ARTs: Microfluidics as a Tool for Sperm Selection
Andrology, EarlyView.ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

Prevention of fertilization by exposure of hamster eggs to soluble acrosin [PDF]
, 1977 Incubation of hamster eggs with trypsin or chymotrypsin, but not with a series of glycosidases or lipases, prevents capacitated spermatozoa from binding to the zona pellucida so that fertilization is prevented (Hartmann & Gwatkin, 1971; Gwatkin ...

ZAN, IZUMO1, and TMEM95 Protein Domains Identify the Physiological Status of the Sperm
Andrology, EarlyView.ABSTRACT Background Infertility is a growing concern, which has led to an increase in the use of assisted reproductive techniques, involving in vitro sperm capacitation. Nonetheless, the optimal capacitation time remains a matter of debate, and it is unknown whether it has an impact on the localization of key membrane proteins.
