ABSTRACT
Bisphenol A (BPA), a xenobiotic estrogenic compound, has been widely used as a plastic monomer. The alterations of
Sertoli and spermatogenic cells in prepubertal rats after short-term (6 and 9 hr) exposure to various concentrations of BPA
in vitro were examined by TUNEL-staining and transmission electron microscopy. The testes of 20-day-old Sprague
Dawley (SD) rats were cut into smaller pieces, and seeded in the medium. At 6 and 9 hr after administration of BPA at
various concentrations (0, 10 nmol.mL-1, 1x10-2 nmol.mL-1, and 1x10-4 nmol.mL-1, respectively), the specimens were
obtained for light and transmission electron microscopic observations. As a result, at 6 hr after exposure to BPA, the
vacuolization within cytoplasm and the nuclear membrane rupture appeared in Sertoli cells. TUNEL-positive
spermatogenic cells were also identified.
Key words: Sertoli cell, Spermatogenic cell, Bisphenol-A (BPA)

ABSTRAK
Bisphenol A (BPA) yang merupakan suatu senyawa estrogenik senobiotik telah banyak digunakan sebagai monomer
plastik. Dalam kaitannya dengan hal tersebut, alterasi sel Sertoli dan spermatogenik dari mencit yang diberi perlakuan
pemaparan dengan berbagai konsentrasi BPA selama 6 dan 9 jam secara in vitro dilakukan dengan TUNEL-staining dan
mikroskop electron transmisi. Testis dari mencit Sprague Dawley berumur 20 hari dipotong-potong menjadi berukukan
kecil dan dibenamkan di dalam medium. Setelah 6 dan 9 jam pemberian BPA pada konsentrasi 0, 10 nmol.mL-1, 1 x 10-2
nmol.mL-1, dan 1 x 10-4 nmol.mL-1, specimen diamati dengan mikroskop electron transmisi dan cahaya. Hasil
pengamatan menunjukkan bahwa setelah dipaparkan terhadap BPA terlihat adanya vakuolisasi dalam sitoplasma dan
‘rupture’ pada membrane inti sel. Sel spermatogenik TUNEL-positive juga dapat teridentifikasi. Alterasi sedemikian rupa
cenderung meningkat secara gradual sesuai dengan perlakukan dosis dan waktu. Perlakuan BPA berhasil engidentifikasi
sel-sel Sertoli dan spermatogenik apototik, dan sel-sel Sertoli dan spermatogenik nekrotik.
