“…Enhanced embryo development and increased numbers of embryonic cells have been reported after incubation of porcine and camelid oocytes with caffeine [29,49]. However, reports on bovine oocytes using other cAMP modulators are conflicting, probably due to the differences in protocols and compounds [43,57,58].…”

“…Improved maturation rates have been reported when caffeine was supplemented during pre-IVM [28]. Oocyte culture in the presence of caffeine increased blastocyst rates and cell numbers, probably by maintaining or even increasing MPF and mitogen-activated protein kinase (MAPK) concentrations in cytoplasts and oocytes [29][30][31].…”

“…Penambahan kafein selama delapan jam sebelum akhir periode maturasi pada penelitian ini memperlihatkan tingkat fertilisasi yang lebih rendah daripada kelompok lainnya. Hal ini kemungkinan disebabkan karena pemaparan oosit yang terlalu lama dalam kafein sehingga mengganggu filamen sitoskeleton dalam oosit seperti yang dilaporkan oleh Mannomani et al (2004) dan Fathi et al (2014). Penambahan kafein selama empat jam akhir periode maturasi baik pada oosit yang dimaturasi selama 24 jam (M24-Kaf-4) atau 28 jam (M28-Kaf-4) dapat memperbaiki tingkat fertilisasi normal (2PN) dan menurunkan tingkat polispermi bila dibandingkan dengan kelompok oosit yang dimaturasi selama 28 jam (M-28) tanpa penambahan kafein (P<0,05).…”

“…Menurut Lee dan Campbell, (2008) breakdown (NEBD) dan peningkatan yang signifikan pada jumlah sel embrio tahap blastosis. Penurunan persentase polispermi pada kelompok oosit yang dimaturasi dengan kafein selama empat jam diduga karena kafein dapat memelihara aktivitas MPF, sehingga dapat mengatur kembali RE dan meningkatkan dinamika Ca 2+ pada oosit sehingga pada saat fertilisasi pelepasan Ca 2+ intraseluler dari RE dapat memediasi blok polispermi (Stricker dan Smythe, 2003;Zhang et al, 2011;McAvey et al, 2002;Fathi et al, 2014). Penambahan kafein pada medium oosit mencit yang mengalami aging telah berhasil mendapatkan anak yang sehat dengan metode intracytoplasmic sperm injection (ICSI) (Ono et al, 2011).…”
