연구실 소개
홍연희 교수의 연구실은 생식 건강과 생식 능력 보존을 핵심으로 삼아, 유방암 환자나 난소기능 저하 위험이 있는 여성들을 대상으로 생식세포 및 난소 조직의 동결 보존 기법을 연구하고 있습니다. 또한 돼지의 경제적 형질과 관련된 유전자 마커를 규명하고, 갈비살세포에서의 지방세포 분화 과정에서의 어드립ок린(Chemerin) 및 수용체 유전자 발현 변화를 분석하여 대사질환과의 연관성을 탐색하고 있습니다. 특히, 난소기능 저하를 유발할 수 있는 질환과 치료법에 대한 영향을 분석함으로써, 임상적 적용이 가능한 생식 보존 전략을 모색하고 있습니다.

15Fertility preservation is a major concern in young patients diagnosed with breast cancer and planning to receive multimodality treatment, including gonadotoxic chemotherapy with or without age-related decline through long-term endocrine therapy. Most breast cancer patients undergo multimodality treatments; many short-term and long-term side effects arise during these therapies. One of the most detrimental side effects is reduced fertility due to gonadotoxic treatments with resultant psychosocial
To identify genetic markers associated with economic traits in pigs, 157 microsatellite markers were examined in Yorkshire pigs. Thirty eight female Yorkshire pigs were initially examined and six of them were selected as progenitors; half were more than 1.5 standard deviations (SD) above the mean for average daily gain (ADG) and backfat thickness (BFT), and the remaining half were more than 1.5 SD below the mean. These pigs were then mated to male Duroc pigs, and 200 F2 pig offspring were examin
Adipokines, adipocyte-derived protein, have important roles in various kinds of physiology including energy homeostasis. Chemerin, one of adipocyte-derived adipokines, is highly expressed in differentiated adipocytes and is known to induce macrophage chemotaxis and glucose intolerance. The objective of the present study was to investigate the changes of chemerin and the chemokine-like-receptor 1 (CMKLR1) gene expression levels during differentiation of the bovine adipocyte and in differentiated
Adverse symptoms were common and discontinuation rate was somewhat higher during short-term course of ulipristal acetate. Information about incidence of various adverse symptoms should be given to women who willing to take ulipristal acetate.
The prevalence of APA is low in Korean infertile women undergoing the first IVF cycle, and the presence of APA appears to neither decrease their first IVF success nor increase abortion rate.
Endometrioma is known to reduce the ovarian reserve and the extent of the decrease is more severe when ovarian surgery is performed. Therefore, to prevent this decline in fertility, patients with endometrioma are considered candidates for preoperative fertility preservation (FP). In this study, we evaluate the efficacy of FP in women with endometrioma before planned ovarian surgery. A total of 95 cycles in 62 patients with endometrioma, undergoing controlled ovarian stimulation (COS) for FP usin
This study demonstrated that the awareness and knowledge about elective OC were relatively poor among the female Korean population. These findings may help clinicians in better counselling of their patients.
Dual triggering can be an efficient maturation method to maximize the yield of mature oocytes in breast or endometrial cancer patients using letrozole-combined GnRH antagonist protocol for FP.
This study aimed to investigate the factors affecting blastocyst formation rate. One hundred and seven fresh <i>in vitro</i> fertilisation (IVF) and elective day 5 blastocyst transfer cycles were selected. Univariate and multivariate analyses revealed that intracytoplasmic sperm injection (ICSI) (<i>r</i> = -.236, <i>p</i> = .014 vs. <i>p</i> = .005) was advantageous for blastocyst formation. In addition, the number of mature oocytes (<i>r</i> = -.274, <i>p</i> = .004 vs. <i>p</i> = .002) was a
Coadministration of imatinib or dasatinib with Cp could preserve AMH production capacity in this in vitro mice preantral follicle culture model, and it did not affect MII oocyte acquisition.
The top-quality embryo score at transfer and the degree of post-warming embryo development were associated with clinical pregnancy in vitrified cleavage-stage embryo transfer cycles. In vitrified blastocyst transfer cycles, the top-quality blastocyst score at transfer was the only significant factor affecting clinical pregnancy.
Here, we reported the case of a 32-year-old pregnant woman who presented with sudden abdominal pain at 5 weeks of gestation and diagnosed as ruptured heterotopic ovarian pregnancy. She was conceived after <i>in vitro</i> fertilization. Right ovarian pregnancy was noticed, and we performed right ovarian wedge resection via single-port access laparoscopic surgery. Intrauterine pregnancy had remained intact, and she delivered a term baby. Rapid diagnosis in early gestation and minimally invasive la
