Environmental chemicals impact dog semen quality in vitro and may be associated with a temporal decline in sperm motility and increased cryptorchidism [PDF]

, 2016
Adverse temporal trends in human semen quality and cryptorchidism in infants have been associated with exposure to environmental chemicals (ECs) during development.

EP300‐interacting inhibitor of differentiation 3 is required for spermatogenesis in mice

Andrology, EarlyView.
Abstract Background Mammalian spermatogenesis is a highly complex process of cell proliferation, meiosis, and differentiation. A series of genes are expressed in an orderly and precise manner to ensure spermatogenesis, with chromatin undergoing intricate changes throughout.

Role of intra‐individual variation in the detection of thresholds for DFI and for misclassification rates: A retrospective analysis of 14,775 SCSA® tests

Andrology, EarlyView.
Abstract Background Sperm DNA damage is associated with reduced male fertility after natural conception and intrauterine insemination. However, the impact on in vitro fertilization (IVF) and especially intracytoplasmic sperm injection (ICSI) treatments is still unclear.

Experience in Optimising Fertility Outcomes in Men with Congenital Adrenal Hyperplasia due to 21 Hydroxylase Deficiency. [PDF]

, 2016
OBJECTIVE: Men with congenital adrenal hyperplasia (CAH) have impaired fertility. We aimed to assess fertility outcomes and the importance of hypogonadotropic hypogonadism, testicular failure and the presence of testicular adrenal rest tumours (TART ...

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

A WHO 2021‐based comprehensive scheme outlining sperm parameters’ associations with IVF outcomes in PGT‐A cycles

Andrology, EarlyView.
Abstract Objective To examine the association between semen parameters, assessed according to World Health Organization (WHO)‐2021 criteria, and paternal body mass index (BMI) and age, with embryological and clinical outcomes in ICSI cycles involving preimplantation genetic testing for aneuploidy (PGT‐A).

Sperm retrieval techniques in azoospermic patients: PESA, MESA, TESA, TESE and MICROTESE [PDF]

Einstein (São Paulo), 2009
Azoospermia is defined as the absence of mature spermatozoa in semen analysis after centrifugation. The causes of azoospermia may be related to spermatogenesis defects and classified as non-obstructive azoospermia, or to the obstruction of the efferent ...

Cellular distribution of aquaporins in testes of normal and cryptorchid dogs: A preliminary study on dynamic roles [PDF]

, 2019
Fluid regulation within the male gonad is an important process for promoting sperm differentiation and maturation. Aquaporins (AQPs) are a family of thirteen integral membrane proteins involved in these processes.

Effects of AZFc (b2/b4, b1/b3, b2/b3, and gr/gr) deletions and primary duplications on the outcomes of the first intracytoplasmic sperm injection treatment cycle: A single‐center retrospective cohort study

Andrology, EarlyView.
Abstract Background Current advances in high‐throughput sequencing technology enable the precise identification of Y chromosome microdeletion and primary duplication in infertile couples, but the mechanism and clinical significance of these mutations in assisted reproductive techniques remain unclear.
