"Selama oogenesis, oosit tumbuh dalam ukuran dan memperoleh kompetensi pematangannya. Kompetensi pematangan oosit sangat diperlukan untuk mendukung terjadinya fertilisasi dan perkembangan embrio berkualitas baik. Ketidakmampuan untuk menentukan oosit yang berpotensi menghasilkan embrio yang viable masih menjadi kendala utama pada proses Fertilisasi In Vitro (FIV). Penelitian ini bertujuan mengetahui apakah ukuran diameter oosit bisa menjadi prediktor kualitas oosit dan embrio. Penelitian ini menggunakan desain penelitian prospektif cohort. Metode penelitian untuk pengukuran diameter oosit menggunakan aplikasi Image J, setiap oosit dan sel granulosa dikelompokkan sesuai ukuran diameter oosit, oosit dilakukan fertilisasi dengan teknik ICSI/IMSI kemudian diikuti perkembangan embrio sampai hari ke-5. Pemeriksaan ELISA dipakai untuk mengkonfirmasi kualitas oosit dengan melihat kadar protein Akt dan total Akt pada sel granulosa kumulus oosit, sedangkan untuk mengkonfirmasi kualitas embrio adalah dengan melihat parameter morfokinetik embrio, pencapaian blastokista dan frekuensi abnormalitas pembelahan. Hasil penelitian menunjukkan tidak ada perbedaan signifikan (P>0,05) pada kadar protein p-Akt dan total Akt sel granulosa kumulus antara ketiga kelompok. Selain itu pengamatan morfokinetik embrio menunjukkan tidak ada perbedaan signifikan (P>0.05) kecuali parameter S2, begitu pula dengan pencapaian blastokista serta frekuensi abnormalitas pembelahan kecuali parameter reverse cleavage (RC). Kesimpulan yang didapat dari penelitian ini adalah ukuran diameter oosit tidak mempengaruhi kualitas oosit dan embrio. Ukuran diameter oosit tidak bisa menjadi prediktor kualitas oosit dan embrio, karena tidak ada perbedaan signifikan pada kualitas oosit dan embrio ketiga kelompok. Oosit dengan ukuran diameter kecil memiliki potensi untuk menjadi embrio dengan kualitas baik.

During oogenesis, oocytes grow in size and acquire maturation competence. Oocyte maturation competence is necessary to support fertilization and the development of good quality embryos. The inability to determine which oocytes have the potential to produce viable embryos remains a major obstacle in the In Vitro Fertilization (IVF). This study aims to determine whether oocyte diameter can be a predictor of oocyte and embryo quality. This study used a prospective cohort research design. The method used for measuring oocyte diameter using Image J application. Each oocyte and cumulus granulosa cells is grouped according to the size of oocyte diameter, oocyte are fertilized with ICSI/IMSI techniques and then followed by embryo development until day 5. ELISA examination is used to confirm oocyte quality by looking at p-Akt and Akt total protein levels in oocyte cumulus granulosa cells, while to confirm embryo quality by looking at the morphokinetic embryo, blastocyst achievement and frequency of cleavage abnormalities. The results showed no significant difference (P>0.05) in p-Akt and Akt total protein levels in cumulus granulosa cells between the three groups. In addition, morphokinetic observation of embryos showed no significant difference (P>0.05) except S2 parameter, as well as the achievement of blastocyst and the frequency of cleavage abnormalities except the reverse cleavage (RC) parameter. The conclusion obtained from this study is that the size of the oocyte diameter does not affect the quality of oocytes and embryos. Oocytes diameter size can not be a predictor of oocyte and embryo quality, because there is no significant difference in the quality of oocytes and embryos of the three groups. Oocytes with a small diameter size have the potential to become embryos with good quality."

Background: In vitro fertilization (FIV) is one of the most widely practiced infertility treatment methods in the world. The quality of embryos in FIV is strongly influenced by the number and quality of oocytes. AMH level is a marker routinely checked on FIV program participants. However, it is not clear the relationship between AMH and the quality and quantity of oocytes.

Method: This study is a retrospective observational analytic study with a cross-sectional design on all FIV program participants aged 18-45 years at the Yasmin Clinic, RSCM Kencana, Jakarta, from January 2013 to December 2019. Sampling was carried out by total sampling. Subjects with incomplete data, having infertility etiology in the form of polycystic ovary syndrome, endometriosis, and sperm factors were excluded from the study. Data on AMH levels, total oocyte count, mature oocytes, fertilized oocytes, and fertilization rate were obtained by the patient.

Result: There were 692 subjects who met the inclusion and exclusion criteria. In the bivariate analysis, there was a strong correlation between AMH levels and the total number of oocytes (r = 0.650, p <0.001), the number of mature oocytes (r = 0.642, p <0.001), and the number of fertilized oocytes (r = 0.607, p <0.001), whereas there was no correlation between AMH levels and fertilization rate (r = 0.076, p = 0.049). After controlling age and body mass index, a correlation was found between AMH levels with total oocyte count, mature oocyte count, fertilized oocyte count, and fertilization rate (p <0.05). Based on the analysis, cut-off of AMH level to predict optimal total oocyte is 1.615 ng/mL (sensitivity 77%, specificity 77.3%).

Conclusion: Serum AMH levels correlate with the total number of oocytes, the number of mature oocytes, the number of fertilized oocytes, and fertilization rate."

"Latar Belakang: Infertilitas adalah suatu kondisi di mana pasangan gagal menghasilkan keturunan setelah 12 bulan melakukan hubungan seksual, tanpa alat kontrasepsi. Infertilitas wanita yang disebabkan oleh berbagai faktor merupakan masalah yang dapat meningkat dalam beberapa tahun ke depan. Salah satu penanganan infertilitas adalah teknologi reproduksi berbantuan seperti IVF dan ICSI yang keberhasilannya dipengaruhi oleh banyak faktor, terutama viabilitas oosit. Viabilitas oosit sendiri dipengaruhi oleh berbagai faktor seperti zat gizi yang mengandung seperti asam lemak tertentu dan isoflavon. Kedelai (Glycine max) diketahui mengandung berbagai zat yang dapat mempengaruhi viabilitas oosit, namun belum ada penelitian mengenai pengaruh konsumsi kedelai.Tujuan : Penelitian ini bertujuan untuk mengetahui pengaruh kedelai terhadap viabilitas oosit yang diukur dengan potensial membran mitokondria.Metode : Penelitian ini merupakan penelitian eksperimen dengan hewan coba. Mencit betina galur Swiss (Mus musculus) umur 6 minggu dibagi menjadi beberapa kelompok, dimana setiap kelompok harus menghasilkan 16 oosit yang diberi pakan kedelai 120 g/KgBB dan yang tidak. Mencit diberi perlakuan sampai umur 8 minggu. Pada umur 8 minggu, mencit diterminasi untuk diambil oositnya. Oosit kemudian diperlakukan dengan protokol MitoTracker (ThermoFisher) dan dilihat menggunakan mikroskop confocal untuk melihat intensitas warna, yang kemudian dianalisis dengan perangkat lunak ImageJ.Hasil: Rata-rata intensitas warna pada kelompok yang diberi kedelai lebih tinggi (27154.63) dibandingkan dengan kelompok yang tidak diberi (19036.42). Namun, perbedaan ini tidak signifikan secara statistik jika diuji menggunakan uji-t independen dengan p > 0,05).Kesimpulan: Rata-rata intensitas warna kelompok dengan kedelai lebih tinggi tetapi perbedaannya tidak nyata. Kurangnya signifikansi statistik bisa menjadi hasil dari ukuran sampel yang kecil.

Background: Infertility is a condition in which a couple fails to produce offspring after 12 months of sexual intercourse, without contraception. Female infertility caused by various factors is a problem that will increase in the next few years. One of the treatments for infertility is assisted reproductive technology such as IVF and ICSI whose success is influenced by many factors, especially oocyte viability. Oocyte viability itself is influenced by various factors such as nutrients that contain certain fatty acids and isoflavones. Soybean (Glycine max) is known to contain various substances that can affect oocyte viability, but there has been no research on the effect of soybean consumption.

Objective : This study aimed to determine the effect of soybean on oocyte viability as measured by mitochondrial membrane potential.

Methods : This research is an experimental study with experimental animals. Female Swiss strain mice (Mus musculus) aged 6 weeks were divided into several groups, where each group had to produce 16 oocytes that were fed 120 g/KgBW soybean and those that were not. Mice were treated until the age of 8 weeks. At the age of 8 weeks, the mice were terminated to collect the oocytes. The oocytes were then treated with the MitoTracker protocol (ThermoFisher) and viewed using a confocal microscope for color intensity, which was then analyzed with ImageJ software.

Results: The average color intensity in the group that was given soybeans was higher (27154.63) than the group that was not given (19036.42). However, this difference was not statistically significant when tested using an independent t-test with p > 0.05).

Conclusion: The average color intensity of the group with soybeans was higher but the difference was not significant. The lack of statistical significance could be a result of the small sample size."
