Effects of kisspeptin on the maturation of human ovarian primordial follicles in vitro.

At this time, with advances in medical science, many cancers and chronic diseases are treatable, but one of their side effects is infertility. Some women also want to delay pregnancy for personal reasons. There has been some evidence that kisspeptin activates broad signals by binding to its receptor, suggesting that the role of kisspeptin in direct control of ovarian function includes follicle growth and steroid production. In this study, the effect of kisspeptin on improving the quality and results for human ovarian follicles was investigated. A section of ovary was removed laparoscopically from women between 20 and 35 years of age (n = 12). Pieces were divided randomly into two groups, control and treatment (with 1 µM kisspeptin). Real-time PCR was performed for GDF9, BMP15 and mTOR gene expression assessments. Western blotting was carried out to measure AKT and FOXO3a protein expression. Data were analyzed using one-way analysis of variance (ANOVA) and Tukey's test; means were considered significantly different at a P-value < 0.05. During treatment with the kisspeptin group, maturity genes are expressed. Therefore, kisspeptin is an effective substance to improve the quality of the human ovarian medium as it increases the maturity of follicles.

The effect of kisspeptin on the maturation of human ovarian follicles in culture following vitrification-thawing processes.

OBJECTIVE: Ovarian cryopreservation is one of the effective methods to preserve fertility for cancer patients. Still, this approach has some problems, namely ROS, resulting in adverse effects on oocytes and ovarian follicles. Kisspeptin as an antioxidant to control ovarian function, directly or indirectly. In this study, the effect of kisspeptin on follicle maturation was evaluated in culture following ovarian cryopreservation. METHODS: Ovarian tissue samples of women between 20 and 35 years old (n=12) were laparoscopically collected. The samples were randomly divided into four groups: 1) control, 2) vitrification, 3) vitrified+1µM kisspeptin, and 4) vitrified+10µM kisspeptin. After vitrification and thawing processes, the tissues were cultured in DMEM medium for 7 days. H&E staining for histological evaluation, Real-Time PCR for GDF9 and BMP15 gene expression, and immunohistochemical staining for GDF9 and BMP15 protein expression were performed. RESULTS: In the vitrification group, ovarian tissue morphology was incoherent, and more primordial follicles than other follicle types were found. The expression of GDF9 and BMP15 genes and proteins were significantly decreased in this group compared with other groups (p<0.05). In the vitrification groups with kisspeptin (1 and 10 µM), the number of primary and secondary follicles was more than in the vitrification group. Besides, the expression of these genes and proteins was dramatically elevated in the vitrification groups with kisspeptin compared to the vitrification group alone (p<0.05). CONCLUSIONS: It seems that kisspeptin is an effective substance to improve the quality of the human ovarian cryopreservation medium by improving follicle maturation.

Kisspeptin decreases the adverse effects of human ovarian vitrification by regulating ROS-related apoptotic occurrences.

Kisspeptin is characterized as a neuropeptide with a pivotal function in female and male infertility, and its antioxidant properties have been demonstrated. In this study, the effects of kisspeptin on the improvement of the vitrification and thawing results of human ovarian tissues were investigated. In this work, 12 ovaries from patients who underwent hysterectomy were collected laparoscopically, and then 32 samples from each of their tissues were taken. Haematoxylin and eosin (H&E) staining was performed to check the normality of the ovarian tissue and, subsequently, the samples were allocated randomly into four groups, including: (1) fresh (control), (2) vitrification, (3) vitrified + 1 µM kisspeptin, and (4) vitrified + 10 µM kisspeptin groups. After vitrification, thawing, and tissue culture processes, H&E staining for tissue quality assessment, terminal deoxynucleotidyl transferase dUTP nick end labelling assay for apoptosis evaluation, and malondialdehyde (MDA), superoxide dismutase (SOD), and ferric reducing ability of plasma tests for oxidative stress appraisal were carried out. Our histological results showed incoherency of ovarian tissue morphology in the vitrification group compared with other groups. Other findings implicated increased apoptosis rate and MDA concentration and reduced SOD activity and total antioxidant capacity (TAC) in the vitrification group compared with the control group (P < 0.05). Moreover, decreased apoptosis rate and MDA concentration, and increased TAC and SOD function were observed in the vitrification with kisspeptin groups (1 µM and 10 µM) compared with the vitrified group (P < 0.05). Our reports express that kisspeptin is an effective agent to overcome the negative effects of vitrification by regulating reactive oxygen species-related apoptotic processes.

Evaluation of Predicting Factors Affecting Sperm Retrieval in Patients with Klinefelter Syndrome: A Prospective Study.

BACKGROUND: This study aimed to evaluate the predicting factors affecting sperm retrieval. We prospectively assessed the relationship between sonographic and microdissection testicular sperm extraction (mTESE) findings in Klinefelter syndrome (KS). MATERIALS AND METHODS: In this prospective study, 44 azoospermic men with 47, XXY karyotypes participated in this study. In order to evaluate the amount of blood supply in different parts of testicular tissue, a doppler ultra-sonographic was performed. Also, for the detection of sperm in this group mTESE technique was performed. RESULTS: The age average of positive mTESE and negative mTESE groups was 29.4 and 33.6 years, respectively. By comparing the testicle volume (based on the data obtained from the clinical examinations conducted by the urologist) it was determined that there is no significant difference between mTESE positive and negative groups. Folliclestimulating hormone (FSH) levels in men with negative mTESE (P=0.03) and testosterone levels in men with positive mTESE significantly increased (P=0.017). The overall rate of testis vascularity was significantly higher in the positive mTESE group than in the negative mTESE group. The clinical pregnancy rate in positive mTESE men was 9% per cycle, 16.6% per embryos were transferred (ET), and 12.5% per cycle. CONCLUSION: Totally, our observation indicated that there is not a significant relationship between sonographic and mTESE results in KS patients. However, more investigations with bigger sample Size can be useful to validate our results.

Endometrial cell-derived conditioned medium in combination with platelet-rich plasma promotes the development of mouse ovarian follicles.

Fertility preservation is one of the most important issues in assisted reproductive technology. Previous studies have shown that cytokines and growth factors can improve follicle growth. The endometrial stromal cells secrete various factors that are involved in maintaining the integrity of uterine and epithelial secretory function. The platelet-rich plasma contains a large assembly of platelets suspended in plasma that successfully improves the viability and growth of various cell lines. This work aimed to investigate the influences of conditioned medium (CM) and platelet-rich plasma (PRP) on the development of ovarian follicles in infertile mice due to cyclophosphamide (CYC) exposure. In this study, 65 healthy BALB/c female mice (∼28-30 g and 6-8 weeks old) in five groups were studied. Immunohistochemistry (IHC) was used to detect growth differentiation factor 9 (GDF9)-positive cells. The mRNA expression levels of SMAD1, SMAD2, and BMP15 was assessed using reverse transcription-polymerase chain reaction (RT-PCR) method. The expression levels of SMAD1, GDF9, BMP15, and SMAD2 in the CM+PRP group was significantly more than in the CM and PRP groups. In addition, live birth occurred in the CM+PRP group. Treatment with CM+PRP in infertile mice due to Cy exposure increased fertility and live-birth rate. In general, our study suggested that the CM and PRP combination could improve the growth of mice ovarian follicles in vivo.

Background and aims: Substance use among adolescents is one of the most challenging behavioral disorders with direct consequences. It is of the essence (that) the prevalence of substance use is investigated among Iranian male adolescents. Methods: The present study is a systematic review and meta-analysis. All published articles titled "prevalence of substance use among Iranian adolescents" authored in Persian and English from 2004 to 2020 on Pub Med, Scopus, SID, and Google Scholar, a top list of academic research databases, were reviewed. Thirty-three out of 805 articles, hinge on the inclusion and exclusion criteria, were eligible. Statistical analysis carried out in STATA 14.0.Q index, I2 index, and χ 2 test were applied. Results: Overall prevalence reported with (95% confidence interval) for substance use 7% (4%-11%), methamphetamine 4% (3%-6%), tobacco 10% (3%-19%), and any addictive substances 4% (2%-7%) among male adolescents respectively. Besides, overall prevalence of alcohol consumption reported 10% (8%-11%). Conclusion: The prevalence of substance use among male adolescents is high, so it is indispensable for researchers to pay special attention to this issue.

Accuracy of Paris 2016 System for Non-invasive Diagnosis Bladder Malignancy.

Background & Objective: The Paris System for Reporting Urinary Cytology (TPS) is a new method for evaluating urinary cytology designed to reduce unreproducible reports. The aim of this study was to reclassify and compare urinary cytology reports with TPS criteria to determine the frequency of unreproducible reports compared to the previous system. Methods: In this study, the laboratory electronic registration system analyzed patients' urine samples taken by voided or washing and brushing methods. The cytological evaluation was performed considering the previous system and TPS by a pathologist. The results of the two systems were compared, and the sensitivity and specificity of TPS were calculated. Results: Urine samples were taken from 876 patients. The mean age of patients was 63.36 ± 12.62. Comparing the routine classification system and TPS, it was observed that the number of atypical reports in the TPS system decreased by 12%, and all of these cases were downgraded to the negative group in the new classification. The sensitivity and specificity of TPS were 29.4% and 95.1%, respectively, if suspected malignancy and positive reports for malignancy were considered. Finally, if positive reports for malignancy were selected, sensitivity and specificity changed to 11.8% and 100%, respectively. Conclusion: Although the TPS system has low sensitivity for the diagnosis of urothelial malignancies, due to its high specificity, it is possible to consider and use this classification for screening patients.

Relationship between long-term use of Ritalin and semen parameters in patients referred to psychiatric centres.

Some studies have shown that Ritalin can interfere with the growth and development of the reproductive system and can also have a serious and harmful effect on sperm parameters, so we decided to conduct studies in this field on the human sample. In a case-control study, 100 adult men aged 21-31 years with hyperactivity were divided into two groups of 50 past users and 50 current users and, 50 patients who had not used Ritalin before were included as the control group. Data were analysed using SPSS software, version 20. Analysis of variance, Pearson correlation coefficient, and regression analysis was used to assess the correlation between variables. The results also showed that there was a statistically significant difference between the current users and the control group in terms of sperm count, abnormality, and motility (p < .47). Comparison of the user group in the past and the control group showed that there was no statistically significant difference in terms of sperm count (p < .59), but there was a significant difference in terms of sperm motility and abnormality between the two groups (p < .001). The present study showed that long-term use of Ritalin can have negative effects on sperm parameters in humans.

Effect of endometrial cell-conditioned medium and platelet-rich plasma on the developmental competence of mouse preantral follicles: An in vitro study.

OBJECTIVE: The aim of this study was to evaluate the impacts of platelet-rich plasma (PRP) and conditioned medium (CM) derived from endometrial stromal cells on mouse preantral follicle culture in a two-dimensional system to produce competent mature oocytes for fertilization. METHODS: In total, 240 preantral follicles were isolated from female mouse ovarian tissue and divided into four groups. The preantral follicles were isolated three times for each group and then cultured, respectively, in the presence of alpha minimum essential medium (control), PRP, CM, and PRP+CM. The in vitro growth, in vitro maturation, and cleavage percentage of the preantral follicles were investigated. Immunocytochemistry (IHC) was also conducted to monitor the meiotic progression of the oocytes. Additionally, the mRNA expression levels of the two folliculogenesis-related genes (Gdf9 and Bmp15) and two apoptosis-related genes (Bcl2 and Bax) were investigated using real-time polymerase chain reaction. RESULTS: In the PRP, CM, and PRP+CM groups, the preantral follicle maturation (evaluated by identifying polar bodies) were greater than the control group. The cleavage rate in the CM, and PRP+CM groups were also greater than the control group. IHC analysis demonstrated that in each treatment group, meiotic spindle was normal. In the PRP+CM group, the gene expression levels of Bmp15, Gdf9, and Bcl2 were greater than in the other groups. The Bax gene was more strongly expressed in the PRP and control groups than in the other groups. CONCLUSION: Overall, the present study suggests that the combination of CM and PRP can effectively increase the growth and cleavage rate of mouse preantral follicles in vitro.

Comparison of the efficacy of bone morphogenetic protein-4 on in vitro differentiation of murine adipose and bone marrow mesenchymal stem cells into primordial germ cells.

Background and purpose: In vitro development of functional gametes from pluripotent stem cells is a promising prospect to treat infertility. Mesenchymal stem cells with a high degree of plasticity and less tumorigenicity are a reliable source of stem cells for the generation of gametes. The present study aimed to compare the differentiation potential in the mesenchymal stem cells that are derived from bone marrow (BMDMSCs) and adipose tissue derived mesenchymal stem cells (AD-MSCs) into germ cells in a culture medium containing bone morphogenic protein-4 (BMP-4). Experimental approach: In this study, MSCs were isolated from both bone marrow and adipose tissue of murine samples. To further verify the nature of the harvested stem cells, their multipotency and surface marker were examined. The identified stem cells were cultured in a medium supplemented with 0 and 25 ng/mL of BMP-4 for 4 days. Flow cytometry analysis, immunofluorescence staining, and real RT-PCR were used to assess the expression levels in germ cell-specific biomarkers (Mvh, Dazl, Stra8, and Scp3). Findings/Results: CD44+, CD45-, CD31-, BMD-MSCs, and AD-MSCs showed to be capable of differentiating to osteo-adipogenic lineages. The flow cytometry, immunofluorescence, and RT-PCR results indicated that early germ cell markers (Mvh and Dazl) were expressed in both types of cells but they were significantly higher in BMD-MSCs than AD-MSCs. Conclusion and implications: Based on our results, the addition of exogenous BMP4 to the culture medium could differentiate BMD-MSCs and AD-MSCs into primordial germ cells, but it is inadequate to further develop into late germ cells in vitro. Moreover, the results revealed that, although AD-MSCs were easier to collect and had faster growth and proliferation rates than BMD-MSCs, the BMD-MSCs were better capable of differentiation into primordial germ cells. They may serve to be considered a more suitable source of MSC for in vitro generation of gametes than AD-MSCs.

In vitro growth of the ovarian follicle: taking stock of advances in research.

Several factors are necessary for the growth and survival of healthy follicles in the folliculogenesis process, including endocrine and paracrine glands, and a regulated ratio of granulosa cells to oocytes. One of the most powerful methods for studying folliculogenesis is the culture of ovarian follicles and oogenesis within a completely controlled environment. Follicle culture systems are highly developed and are rapidly evolving. However, the methods for separating the follicles, the cultivation techniques, the culture medium, and the dietary and hormonal supplements vary depending on the species studied. This study made a literature review of follicular culture techniques, and we investigated the heterogeneity among these key variables in follicular culture.

A review of methods for preserving male fertility.

Male infertility is responsible for 50% of men's health problems and has always been a concern for personal and social issues. A survey of global statistics suggests an increase in infertility rate as one of the critical issues documented in studies. There are different ways of maintaining fertility in men, depending on their age. In this paper, we review the preservation methods used for fertility treatment in Iran and other countries. Available data were reviewed from Google Scholar, PubMed, Scopus, Web of Science, IranMedex, MEDLIB, IranDoc and Scientific Information Database and searched for articles published up to 2018, using the medical subject heading (MeSH) terms for cryopreservation, sperm, testicular, spermatogonia stem cell, male infertility and/or Iranian and in the world, to provide evidence from evaluation of fertility preservation the methods. Based the search strategy, 274 manuscripts were found. After reviewing the titles, abstracts and manuscripts in their entirety, 119 articles were obtained and selected according to the eligibility criteria. The 85 studies mentioned above were divided into three categories (sperm, testis, and spermatogonia stem cells (SSCs)), and methods of fertility preservation were investigated. Ways to maintain male fertility were different depending on age, and included sperm, testicular, and SSC freezing. The number of studies on testicular tissue and SSCs was low for human samples, and more studies are still needed. Sperm freezing at infertility centres is the top for male fertility preservation.

A survey on infertility in men and its relation to risk factors in selected provinces of Iran.

OBJECTIVE: Infertility in men cause significant morbidity and mortality, unfortunately there is not enough information about it due to the lack of a registry in the country. The purpose of this study was to determine the frequency of infertility in men and its association with risk factors. METHODS: This cross-sectional study used data from a nation-wide project on reproductive morbidities among males in Iran in 2007. 2,293 men aged 25-60 years were selected from four provinces across the country including, Golestan Province in the North, Hormozgan Province in the South, Kermanshah Province in the West, and Isfahan Province by cluster sampling scheme. Then, we determined the frequency of infertility in married men, and related risk factors such as smoking, infection, trauma, etc. RESULTS: Of the 2,293 men interviewed, 2,076 were married, 78 were infertile; current primary and secondary infertility was estimated at 3.75%. The incidence of infertility in urban areas was significantly higher than in rural areas (p value<0.003), and finally the clinically male infertility was estimated at 2%. CONCLUSIONS: We need to explain that this project was a cross-sectional study. Therefore, it is recommended that more studies be conducted for accurate estimates of infertility in Iranian men.

Circulating levels of asprosin and its association with insulin resistance and renal function in patients with type 2 diabetes mellitus and diabetic nephropathy.

INTRODUCTION: Adipokines play an important role in the development of type 2 diabetes mellitus (T2DM) and its complications like nephropathy. Asprosin is a newly discovered adipokine involved in glucose metabolism and inflammation process. The present study aimed to evaluate asprosin levels in patients with T2DM and T2DM + nephropathy (NP) compared to control subjects as well as investigating its relationship with insulin resistance, inflammation, and renal function markers. METHODS: Serum levels of asprosin, adiponectin, IL-6, and TNF-α were measured in 55 control subjects, 54 T2DM, and 55 T2DM + NP patients using ELISA kits. RESULTS: Asprosin was found to be higher in the T2DM (6.73 ± 1.67) and T2DM + NP (7.11 ± 1.54) patients compared to the controls (4.81 ± 1.09) (p < 0.001), while adiponectin indicated a lower concentration in both patient groups compared to the control group. Moreover, IL-6 and TNF-α indicated higher levels in the two patients group compared to the control group. Asprosin was observed to have a positive correlation with HbA1c, FBG, TC, LDL-C, IL-6, and TNF-α in the T2DM group. In the patients with T2DM + NP, asprosin was found to be positively correlated with BMI, HbA1c, insulin, HOMA-IR, Cr, UAE, IL-6, and TNF-α, and it was inversely correlated with eGFR. CONCLUSION: Higher concentrations of asprosin in the T2DM and T2DM + NP groups and its relationship with glucose and lipid metabolism and markers of renal function and inflammation suggested a possible role for this adipokine in the pathogenesis of both T2DM and nephropathy.

Coding and Non-Coding RNAs, as Male Fertility and Infertility Biomarkers.

Semen analysis is usually the first step in the assessment of male fertility. Although analyzes provide valuable information about male fertility, success of cytoplasmic sperm injection using this method is not predictable. In the recent years, studies have shown that sperm quality assessment helps clinicians predict male fertility status based on the expression of biomarkers. To write this article, a comprehensive study was conducted on several RNA transcripts by searching related words on medical information databases by 2018. According to the literature, spermatogenesis based disorders in male infertility have a significant relationship with the expression level of some RNA molecules (like DAZ and PRM1/PRM2 ratio) in semen and testicular tissue. Thus, they might be used as predictor biomarkersto evaluate success rate of testicular sperm extraction (TESE) procedure, but confirmation of this hypothesis requires more extensive research. By comparing the number of RNAs attributed to each fertility disorder in men, it is possible to trace the causes of disease or return fertility to some infertile patients by regulating the mentioned molecules. Further researches can provide a better understanding of the use of RNA expression profiles in the diagnosis and treatment of male infertility.

Association of the MTHFR 677C>T and 1298A>C polymorphisms and male infertility risk: a meta-analysis.

BACKGROUND AND OBJECTIVES: One of the possible male sterility risk factors are polymorphisms of Methylenetetrahydrofolate reductase (MTHFR). However, the epidemiologic investigations described inconsistent results regarding MTHFR polymorphism and the risk of male infertility. For that reason, we carried out a meta-analysis of published case-control studies to re-examine the controversy. METHODS: Electronic searches of Cochrane, EMBASE, Google Scholar, and PubMed were conducted to select eligible studies for this meta-analysis (updated to May 2019). According to our exclusion and inclusion criteria, only high-quality studies that remarked the association between MTHFR polymorphisms and male infertility risk were included. The Crude odds ratio (OR) with a confidence interval of 95% (CI) was used to assess the relationship between MTHFR polymorphism and male infertility risk. RESULTS: Thirty-four case-control studies with 9662 cases and 9154 controls concerning 677C/T polymorphism and 22 case-control studies with 5893 cases and 6303 controls concerning 1298A/C polymorphism were recruited. Both MTHFR polymorphisms had significant associations with male infertility risk (CT + TT vs. CC: OR = 1.37, 95% CI: 1.21-1.55, P = 0.00, I2 = 41.9%); (CC vs. CA + AA: OR = 0.82, 95% CI: 0.52-1.30, P = 0.04, I2 = 50.1%). Further, when stratified by ethnicity, the significant association results were observed in Asians and Caucasians for 677C/T and just Asians for 1298A/C. CONCLUSIONS: Some of MTHFR polymorphisms like MTHFR 677C > T are associated with an elevated male infertility risk. To confirm our conclusion and to provide more accurate and complete gene-environment communication with male infertility risk, more analytical studies are needed.

Bladder Lymphangioma Treated by Holmium Laser: Extremely Rare Case Report.

Introduction: Lymphangioma is a sporadic benign tumor of the bladder. It is a congenital disorder and based on the size of lymphatic spaces, it is divided into 3 types of capillary, cavernous, and cystic. Case Report: In this paper, we presented a 40-year-old woman with microscopic hematuria and a normal urinary ultrasound. Urethrocystoscopy showed a flat 4 mm highlighted strawberry-like lesion on the right lateral wall of the bladder. After a cold cup biopsy, the lesion was coagulated by the holmium: YAG (Ho: YAG) laser. Conclusion: In Bladder Lymphangioma Based on the size of the lesion, partial cystectomy or minimally invasive surgeries such as laser modality would be the principal treatment.

Familial Urethral Stricture, Five Adult Patients Overview.

Congenital stricture, specifically with manifestation in adulthood is extremely a rare cause of urethral stricture and is not associated with known etiologies. It was first described by Cobb et al., and to our knowledge only 5 families were reported in English literatures to have familial urethral stricture.We report two families with urethral stricture including five male patients referred to our tertiary reconstructive urology department during 1994 to 2017. The age and severity of symptoms at presentation are variable; as are the surgical interventions required. There are no phylogenetic, familiar or racial relationship between the two families described.

Retrograde-Assisted Percutaneous Cystolitholapaxy Versus Transurethral Cystolithotripsy With Holmium-YAG Laser: A Retrospective Study.

Introduction: The retrograde approach is a modification that makes the percutaneous cystolitholapaxy (PCCL) a more trendy method, especially in operating rooms with limited facilities. The transurethral approach for bladder calculi lithotripsy by a laser has become popular among urologists. In this study, we investigate the feasibility and safety of retrograde assisted access for PCCL in comparison with transurethral cystolithotripsy by the holmium-YAG laser (Ho: YAG). Methods: According to the type of intervention, the patients were stratified to two matched groups. In the retrograde-assisted percutaneous cystolitholapaxy (RPCCL) group, a Benique was conducted through the urethra into the bladder; palpating the suprapubic region, an about 1.5 cm incision was done over the tip, then an Amplatz sheath was placed over it, treading into the bladder; further cystolitholapaxy was done by a routine order. In transurethral Ho: YAG laser lithotripsy (TULL) via 200 µm fiber vaporize the stone. Results: A total of 124 male patients with the mean age of 50.33±9.64 years and the average stone burden of 3.35±1.07 cm were included in the study. The most common cause of vesical calculi was spinal cord injury. Statistically significant differences were found in terms of the mean operation time in favor of the RPCCL group (P≤0.05) and the mean hospital stay in favor of the TULL group (P≤0.05). The stone-free rate (SFR) was 100% in both methods after a onemonth follow-up. None of the interventions changed to open surgery. There were not any major complications in both methods. Conclusion: RPCCL is a safe and effective method in bladder stone treatment and is applicable in medical centres without Ho: YAG equipment.

Female Fertility Preservation, Clinical and Experimental Options.

Recently, due to tremendous progress in prognosis, diagnosis, and treatment of different kinds of malignancies, demands on fertility preservation were raised significantly in developed countries. Fertility failure is one of the most detrimental consequences of radio/cytotoxic treatment procedures in women who could overcome their cancer disease. For women who are involved in cancer diseases, there are multiple options regarding their fertility preservation and those could be selected according to patient's age, the risk of ovarian involvement, the available time and the type of cancer with different levels of advantages and disadvantages. Although there are multiple options, but embryo cryopreservation and ovarian tissue cryopreservation are the most reliable methods for permature and post-mature puberty, respectively. In addition, other approaches like artificial ovary, isolation and cryopreservation of follicles and mature and immature oocyte preservation are under investigations and the success rate of oocyte vitrification is increasing. Therefore, the techniques have the potential to be used in clinic in near future. The presence of comprehensive consultation, before the onset of any kind of cancer treatment procedures, is an indispensable issue which would help patients to make up their mind in choosing the immediate and the best available fertility preservation option.
