Summary: Chemotherapy exposure does not affect the in vitro maturation (IVM) potential of immature oocytes retrieved from ovarian tissue cryopreservation (OTC), but rather depends on the patient's age. Successful retrieval of immature oocytes from ovarian tissue is negatively affected by chemotherapy and its timing.

Summary: The study evaluated in vitro maturation (IVM) outcomes in 133 chemotherapy naive patients aged 1-35 years. The results showed a gradual increase in IVM rates from 1 to 24 years, with a peak in the 18-24 years group and a decrease in the 25-35 years group. Significantly lower success rates were observed in patients under 6 years old and over 30 years old compared to the 18-24 years group.

Summary: Recent advances in anticancer treatment have greatly improved the survival rate of young females, but one third of cancer survivors still face the risk of ovarian insufficiency and infertility. Several procedures have been developed to preserve fertility, including ovarian surgical transposition, gonadotropin-releasing hormone agonists (GnRH-a) treatment, and oocyte and/or ovarian cortical tissue cryopreservation. Innovative techniques, such as the construction of an artificial ovary and the use of stem cells for neo-folliculogenesis and oocyte development, are under investigation. These techniques offer potential strategies for oncofertility programs and provide hope for young female cancer survivors.

Summary: In vitro oocyte maturation (IVM) has been implemented worldwide, but it is not widely adopted in current in vitro fertilization (IVF) due to the lack of synchronization in protocols and definition criteria, resulting in difficulty in collecting proper outcome data and understanding the exact procedure. This review aims to consolidate the current clinical practice of IVM and explore its theoretical basis, as well as discuss potential future uses and the importance of collaboration among IVM centers for better clinical data collection and safety purposes.

Summary: Advancements in cancer treatment have increased awareness of medical and social issues faced by cancer survivors. Women and transgender men are concerned about the potential negative effects on fertility, especially as more people delay childbearing and have not completed their family at the time of diagnosis. Fertility preservation is rapidly expanding in reproductive medicine, although availability varies by region. Oocyte cryopreservation and ovarian tissue cryopreservation have greatly broadened fertility care options.

Summary: This study demonstrates that oocyte cryopreservation is a feasible and efficient option for fertility preservation in cancer patients, based on the comparison with nononcological patients undergoing in vitro fertilization treatments. The results show that cancer patients who undergo oocyte cryopreservation have a high pregnancy rate and birth rate, indicating the effectiveness of this method in preserving fertility.

Summary: This review highlights the feasibility of fertility preservation (FP) in patients with uterine cervical cancer. While fertility sparing surgery has gained acceptance, the use of other FP methods, such as oocyte and ovarian cortex cryopreservation, is still debated. Stemness technology offers a promising alternative for a safer FP approach in cancer survivors.

Summary: This study investigated the oncologic outcomes of patients with early-stage endometrioid endometrial cancer (EEC) treated with in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) following fertility-sparing treatment (FST). The results showed that live birth was associated with decreased recurrence of EEC, and reducing estrogen levels during controlled ovarian stimulation (COS) may mitigate the risk of endometrial cancer recurrence.

Summary: This study investigates the outcomes and experiences of oocyte vitrification treatment in trans masculine individuals before and after testosterone use. The results show that, on average, 20 oocytes are retrieved after ovarian stimulation, with 17 oocytes being able to be vitrified. The survey identifies hormone injections as the most burdensome aspect of oocyte vitrification treatment. These findings can be utilized to improve gender sensitive fertility counseling and treatment strategies.

Summary: This prospective study assessed ovarian function during and after chemotherapy in young patients with early breast cancer. The study found that 33% of patients still had undetectable AMH values 12 months after the end of chemotherapy, and sequential chemotherapy was associated with a higher risk of persistent amenorrhea. There was no significant association between tumor characteristics, fertility preservation, or recovery of ovarian reserve.

Summary: This study retrospectively examined the potential use of oocyte retrieval and maturation for pediatric patients who undergo ovarian tissue cryopreservation. The IVM success rate was higher in patients not receiving chemotherapy, and the AMH level may be useful for predicting the IVM outcome in patients receiving chemotherapy. Further research on the oocyte maturation process in pediatric patients and understanding the regulators of oocyte maturation are needed to improve the IVM procedure's utility.

Summary: Survival rates for children and adolescents with malignancy have increased due to advances in oncology treatments, but these treatments can have toxic effects on the reproductive organs. Cryopreservation of oocytes and sperm is recognized as an effective strategy for preserving fertility in pubertal patients, while the use of hormonal agonists for ovarian protection is controversial. Ovarian tissue cryopreservation is the only option for prepubertal girls, but the outcomes after transplantation are varied. Immature testicular tissue cryopreservation is experimental for prepubertal boys. Guidelines for fertility preservation exist, but implementation in clinical practice is limited. This review aims to discuss indications, outcomes, and workflow for fertility preservation.

Summary: A questionnaire survey was conducted to investigate the understanding and awareness of fertility preservation (FP) in pediatric patients. The results showed that most children understood that the treatment would affect their fertility, and 88.9% expressed understanding for FP and wished to receive it. Concerns about FP mainly focused on fear, pain, and costs. Children expressed satisfaction and happiness after being provided with information about FP treatment.

Summary: The study found that fertility preservation treatments in Japan had certain standards even in the early stages, but were characterized by a wide range of facilities. Most facilities limited the cryopreservation of eggs and ovaries to patients aged 40-41, with breast cancer being the most common indicated disease.

Summary: The study found that post-hysteroscopic TVUS measurement of pelvic fluid accumulation is feasible and accurate for screening tubal patency. TVUS showed 100% positive predictive value, 82.8% sensitivity, and 100% specificity post-hysteroscopy. Increasing fluid volume did not increase pain, and TVUS can serve as a reliable screening tool for patients with unknown tubal patency, potentially reducing the need for more invasive examinations.

Summary: Granulosa cells generate filopodia-like structures called transzonal projections (TZPs) that provide essential factors to the enclosed oocyte. MYO10 protein is involved in the formation and maintenance of actin-rich TZPs. Depletion of MYO10 leads to a reduction in the number of actin-TZPs.

Summary: The frequency of hereditary breast cancer associated with different mutated genes was determined, and the fertility preservation outcomes among young women with hereditary breast cancer were evaluated. The study found that more than three quarters of positive mutated genes in women with breast cancer are BRCA mutations. Compared to those with non-hereditary breast cancer, women with hereditary breast cancer attained a higher number of cryopreserved embryos.

Summary: This study compared the effects of fixed estrogen dose and increasing estrogen doses during hormone therapy frozen embryo transfer (HT-FET) cycles. The results showed that despite using higher doses of estrogen and longer treatment duration, the increased-dose group had thinner endometrium. However, the pregnancy rates were similar between the two groups.

Summary: This study assessed the effect of frozen-thawed embryo transfer protocol on the live-birth rate and clinical pregnancy rate of single-vitrified-blastocyst transfer. The study found that the live-birth rate and clinical pregnancy rate were higher in natural cycles and modified natural cycles with hCG triggering compared to artificial hormone replacement treatment cycles.
