Ovarian tissue cryopreservation (OTC) is mainly used for fertility preservation in girls and women facing a gonadotoxic treatment. If the woman subsequently becomes menopausal, the ovarian tissue may be transplanted to regain ovarian function, including fertility. The method was developed more than two decades ago and today thousands of women worldwide have undergone OTC. Fewer than 500 patients have had tissue transplanted and close to 100% of those regain ovarian function. Several technical aspects of OTC are now becoming more established, including high quantitative follicle survival, defining the size of the tissue resulting in optimal tissue revascularisation and follicle loss resulting from transport of ovarian tissue prior to freezing. We have used OTC to safeguard fertility in patients with genetic diseases, which for some diagnoses is purely experimental, as no transplantations is yet been performed. Usage of OTC beyond fertility is now also being considered; here, the endocrine function of follicles is the focus. It has been suggested that ovarian tissue stored in the reproductive years may be used to avoid premature ovarian insufficiency (POI) when there is a familial disposition or to postpone menopause in patients with an increased risk of osteoporosis or cardiovascular diseases. The benefit of OTC beyond fertility requires, however, actual clinical studies. The current review includes several recent technical aspects with contributions from Denmark building on some of the early work by Roger Gosden.

Progress in recent years in the efficacy of oncologic treatment and early diagnosis of cancer has determined an increase in life expectance in cancer patients. About 10% of all cancer cases affect women younger than 45 years; therefore nowadays approximately 5-6% of the population in childbearing age consists in cancer survivors. A crucial issue is the high risk of premature ovarian insufficiency due to possible gonadotoxic effects of oncologic treatments. Considering combined chemotherapy, radiation therapy, and bone marrow transplantation, this risk can reach 92-100%, depending on the age and ovarian reserve of the patient, as well as the schedule and type of therapy. International guidelines recommend addressing all the patients diagnosed with a neoplasia treatable with potentially gonadotoxic therapies to fertility preservation. Moreover, fertility preservation also seems to reserve fascinating implications for women who want to delay childbearing for social reasons or women affected with endometriosis, who could receive unexpected opportunities. At present, the most widespread techniques to preserve fertility in adult women are embryo or oocyte cryopreservation, depending on the presence of a partner or according to legislative issues, but these procedures require time for ovarian stimulation. In prepubertal patients or when there is no possibility of delaying chemotherapy, ovarian tissue cryopreservation and subsequent transplantation represent the main strategy.

Abstract Objective The basic pathological changes of primary ovarian insufficiency (POI) include ovarian tissue fibrosis and follicular development disorders. The human umbilical cord mesenchymal stem cell (hUMSC) transplantation has been shown an effective method to improve the ovarian function in POI rat model; however, the exact mechanisms are still unclear. The purpose of this study is to investigate whether the recovery of ovarian function in POI rats is related to the inhibition of tissue fibrosis following hUMSC transplantation. Furthermore, the transforming growth factor-β1 (TGF-β1) signaling pathway is explored to determine the mechanisms of ovarian function recovery through its inhibition of tissue fibrosis. Methods The primary ovarian insufficiency (POI) rat model was established by intraperitoneal injection of chemotherapy drug cisplatin (CDDP) for 7 days. The levels of serum sex hormones were measured using enzyme-linked immunosorbent assay (ELISA). The tissue fibrosis in the ovary was examined using Masson staining and Sirius red staining. The collagen fibers in the ovarian tissues were detected by Western blot analysis. To investigate the mechanisms of ovarian function recovery following hUMSC transplantation, ovarian stromal cells were isolated from the ovarian cortex of immature rats. The expression of Cytochrome P450 17A1 (Cyp17a1) and fibrosis marker of alpha smooth muscle actin (α-SMA) in ovarian stromal cells was examined using immunofluorescence analysis. Also, the protein levels of Cyp17a1 and α-SMA in ovarian stromal cells were examined by Western blot analysis. The expression of TGF-β1 and Smad3 signals was measured by Western blot and quantitative reverse-transcription polymerase chain reaction (qRT-PCR) analysis. Results The results show that the function of the ovary in POI rats was significantly improved after hUMSC transplantation. The expression of fibrosis markers (α-SMA) and production of Collagen Type I (Collagen I) and Collagen Type III (Collagen III) in POI rats were significantly inhibited in POI rats following hUMSC transplantation. In the cultured ovarian stromal cells, the decrease of TGF-β1 and p-Smad3 protein expression was observed in hUMSC-treated POI rats. The treatment with TGF-β1 inhibitor of SB431542 further confirmed this signal pathway was involved in the process. Conclusion Our study demonstrated that the TGF-β1/Smad3 signaling pathway was involved in the inhibition of ovarian tissue fibrosis, which contributed to the restoration of ovarian function in POI rats following hUMSC transplantation.

The tissue fibrosis in ovary was examined using masson staining and Sirus red staining. The collagen fibers in the ovarian tissues were detected by Western blot analysis. To investigate the mechanisms of ovarian function recovery following hUMSCs transplantation, ovarian stromal cells were isolated from the ovarian cortex of immature rats. The expression of Cytochrome P450 17A1 (Cyp17a1) and fibrosis marker of alpha smooth muscle Actin (α-SMA) in ovarian stromal cells were examined using immunofluorescence analysis. Also, the protein levels of Cyp17a1 and α-SMA in ovarian stromal cells were examined by western blot analysis. The expression of TGF-β1 and Smade3 signals were measured by Western blot and quantitative reverse-transcription polymerase chain reaction (qRT-PCR) analysis.Results: The results show that the function of ovary in POI rats were significantly improved after hUMSCs transplantation. The expression of fibrosis markers (α-SMA) and production of Collagen Type I (Collagen Ⅰ) and Collagen Type Ⅲ (Collagen Ⅲ) in POI rats was significantly inhibited in POI rats following hUMSCs transplantation. In the cultured ovarian stromal cells, the decrease of TGF-β1 and p-Smade3 protein expression was observed in hUMSCs treated POI rats. The treatment with TGF-β1 inhibitor of SB431542 further confirmed this signal pathway was involved in the process. Conclusion: Our study demonstrated that the TGF-β1/Smad3 signaling pathway was involved in the inhibition of ovarian tissue fibrosis, which contributed to the restoration of ovarian function in POI rats following hUMSCs transplantation.

Abstract Context: In young women, some treatments for cancer or other conditions (such as sickle cell anemia) may give rise to primary ovarian insufficiency. Ovarian transplantation is one of the available options for fertility preservation, with highly variable pregnancy rates. Objective: The objective of the study was to investigate markers of ovarian reserve and ovarian function in women up to 7 yr after orthotopic ovarian transplantation. Secondary objectives were to assess the relationship between markers of ovarian reserve and pregnancy rate along with the duration of ovarian function. Design: This was a prospective cohort study in 10 women, with a mean follow-up of 2.5 yr. Setting: The study was conducted at a university hospital in Brussels, Belgium. Patients: Patients included 10 women who were about to receive or had previously received gonadotoxic treatment. In seven women cryopreservation of ovarian tissue was performed before starting treatment. Subsequently autografts were orthotopically transplanted in these women. Three women, who had already developed primary ovarian insufficiency due to treatment, underwent orthotopic transplantation of ovarian allograft tissue originating from their human leukocyte antigen-compatible sisters. Main Outcome Measures: Serum concentrations of FSH, LH, estradiol, inhibin B, and anti-Müllerian hormone (AMH) were measured. Results: On average, first menses took place after 4.7 months. Duration of graft functioning varied from 2 to more than 60 months. FSH concentrations remained elevated, whereas estradiol levels normalized and AMH was low to undetectable. Inhibin B varied among women and was not associated with the duration of ovarian function (hazard ratio 0.966, 95% confidence interval 0.881–1.059). Two spontaneous pregnancies occurred. Endocrine characteristics were not significantly different in these women. Conclusions: Low AMH and inhibin B concentrations may suggest decreased ovarian reserve in women after ovarian transplantation. AMH and inhibin B levels may not be associated with the duration of ovarian graft function or probability to achieve a pregnancy.
