Marginal Changes in Semen Quality Over Three Decades (1996‒2022) Among 8320 Men in the Danish Young Men Study (DYMS): Cohort Profile and Trends

Andrology, EarlyView.
ABSTRACT Background Since the 1990s, declining sperm counts and increasing testicular cancer rates have raised worldwide concern about male reproductive health, including in Denmark. This prompted a prospective population‐based study with annual surveillance of semen quality.

Lactate‐Responsive Glycogen Dynamics Are Associated With Bull Sperm Motility and Fertilization Under Glucose‐Limited Conditions

Andrology, EarlyView.
ABSTRACT Background Mammalian sperm need to undergo hyperactivation, capacitation, and acrosome reaction to achieve fertilization competence. However, the female reproductive tract presents contrasting metabolic environments. The uterus is glucose‐rich, and the oviduct is lactate‐rich and glucose‐limited.

A CCNA1 Missense Variant Associated With Chromatid Non‐Disjunction in Abnormal‐Headed Sperm and Male Infertility

Andrology, EarlyView.
ABSTRACT Background Macrozoospermia is a rare form of teratozoospermia characterized by tetraploids, large‐headed spermatozoa with multiple flagella, usually caused by bi‐allelic AURKC mutations. The etiology of atypical phenotypes with a lower proportion of large headed spermatozoa and single flagella however often remains unresolved.

Anatomical and Histological Descriptions of the Male Reproductive System of the Alfalfa Weevil of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae) Using Light and Scanning Electron Microscopies

Acta Zoologica, EarlyView.
ABSTRACT Features of the reproductive organs, such as the number of testicular follicles, testis colour and the morphology of the glands, can be used as systematic characters. For this purpose, this paper was the first description of the male reproductive system anatomy and histology of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae), a ...
