Human sperm chromatin epigenetic potential: genomics, proteomics, and male infertility
Asian Journal of Andrology, 2015 The classical idea about the function of the mammalian sperm chromatin is that it serves to transmit a highly protected and transcriptionally inactive paternal genome, largely condensed by protamines, to the next generation.

Expansion microscopy on Drosophila spermatocyte centrioles
, 2020 Drosophila spermatocyte centrioles are ideal for imaging studies. Their large, characteristic V conformation is both easy to identify and measure using standard imaging techniques.

New insights into the regulation of cholesterol efflux from the sperm membrane
Asian Journal of Andrology, 2015 Cholesterol is an essential component of the mammalian plasma membrane because it promotes membrane stability without comprising membrane fluidity. Given this important cellular role, cholesterol levels are tightly controlled at multiple levels.

eLife, 2021 The male germ cells must adopt the correct morphology at each differentiation stage for proper spermatogenesis. The spermatogonia regulates its differentiation state by its own migration. The male germ cells differentiate and mature with the formation of

Progression through M I in Cap-H2cc3/ Df spermatocyte.
, 2021 Cap-H2cc3/ Df spermatocytes expressing Cenp-A/Cid-EGFP and His2Av-mRFP were analyzed by time-lapse imaging at 45 sec intervals. Progression through M I, as observed in the spermatocyte presented in Fig 4B, is shown in a maximum intensity projection.

Isolation of Sertoli, Leydig, and spermatogenic cells from the mouse testis
BioTechniques, 2011 A thorough understanding of the events during mammalian spermatogenesis requires studying specific molecular signatures of individual testicular cell populations as well as their interaction in co-cultures.

Primary spermatocyte cysts following dicentric chromosome induction.
, 2014 Phase contrast views of a normal testis and yw/DcY(H1); hsFLP2B/+ testis five days after heat shock. The apical portion of a normal testis (A) is filled with cysts, with primary spermatocyte cysts occupying most of the volume.

Ultrastructure of early spermatocyte development in H. membranacea.
, 2023 (A) TEM image of a spermatocyte in prophase of meiosis I. The nucleus (N) exhibits condensed chromatin (Chr) with synaptonemal complexes. Other organelles like the Golgi apparatus (G), the endoplasmic reticulum (ER) and mitochondria (M) are positioned in

Biobanking efforts and new advances in male fertility preservation for rare and endangered species
Asian Journal of Andrology, 2015 Understanding and sustaining biodiversity is a multi-disciplinary science that benefits highly from the creation of organized and accessible collections of biomaterials (Genome Resource Banks).

The spermatocytic seminoma: views on pathogenesis [PDF]
International Journal of Andrology, 1987 The spermatocytic seminoma has clinical and histological characteristics which differ from those of other germ cell tumours of the testis. Classical seminomas and teratomas are believed to originate from intratubular carcinoma‐in‐situ (CIS), which is almost invariably found adjacent to these neoplasms. In addition, DNA analysis of these tumours and the
