简介：AbstractTraditional radiotherapy and chemotherapy often cause irreversible damage to the fertility and endocrine function of cancer patients. The current methods of fertility preservation include freezing the sperms of adult and adolescent males after puberty; freezing the embryos, oocytes, and ovarian tissue of females; and drug intervention and fertility preservation surgery. This article reviews fertility preservation in cancer patients with respect to current methods, indications, and some more recently developed methods that remain under investigation.

简介：AbstractThe source of human oocytes is directly associated with the success of infertility treatment and fertility preservation. The number of oocytes obtained is possibly correlated with the success rate in terms of live birth rates. However, oocyte quality must be refined such that the number of oocytes is not positively correlated with the quality of oocytes. Different ovarian stimulation protocols can be used to obtain numerous oocytes. However, oocyte quality should be considered the most important factor affecting infertility treatment and fertility preservation. Infertile women are generally willing to take health-related risks to achieve a live birth, and ovarian stimulation using high-dose hormonal treatments may be harmful for both women and infants. Therefore, successful infertility treatment and fertility preservation should be defined as the birth of a healthy baby at term without compromising the health and safety of the mother and infant. Therefore, the source of high-quality oocytes must be carefully considered prior to infertility treatment and fertility preservation.

简介：AbstractLong-term and stable preservation of bacteriophages is of crucial importance. Although many efforts have been made in the past decades to explore the influence of external factors on bacteriophage preservation, there is still little understanding, and a systematic description is lacking. In this study, we explored the influence of different factors on the preservation of lytic bacteriophage VP3, one of the typing bacteriophages of Vibrio cholerae O1 biotype El Tor, and attempted to optimize its preservation. We examined external factors, including temperature, solution, and cryoprotectant, in stable cooling/freezing conditions or alternate cooling/freezing and thawing. We found that whether in Luria-Bertani (LB) medium or SM buffer, in terms of 20-week stable cooling or freezing, -20 °C was the most damaging while 4 °C, -80 °C, and -196 °C were protective. Thirteen cycles of alternate cooling/freezing and thawing caused a loss in the survival rates of bacteriophages. The addition of cryoprotectant, glycerol (30%, w/v) or dimethyl sulfoxide (DMSO, 10%, w/v) significantly improved the survival rates of bacteriophages preserved at -20 °C. However, at 4 °C, -80 °C, and -196 °C, the cryoprotectant effect was only slightly positive or even harmful. In summary, for bacteriophage VP3, the best preservation method is to directly preserve the bacteriophage stocks in LB medium at -80 °C or -196 °C instead of storing them in SM buffer or adding cryoprotectant. Our results provided insights into the external influencing factors on bacteriophage VP3 during preservation at low temperature and can be applied to the optimization of bacteriophage preservation in the future.

简介：AbstractMany female fertility preservation-related technologies have recently been developed in response to increasing demand for such treatments. To establish standard practices of female fertility preservation in China, the Chinese Maternal and Child Health Association Affiliated Fertility Preservation Professional Committee assembled specialists to construct a consensus, referring to the current clinical guidelines of some countries combined with clinical practice and expert opinions. The consensus includes two parts: (1) indications for female fertility preservation and related techniques, in which we sought to be inclusive regarding the indications for fertility preservation; and (2) practical guidance for the clinical application of the female fertility preservation technologies.

To improve the understanding of PCOS-related infertility among Chinese obstetricians and gynecologists at all levels for better patient diagnosis and management, we have referred to the international expert recommendations and literature and taken into account the Chinese clinical practice to develop the "Consensus on infertility management and fertility preservation related to PCOS."

简介：AbstractTo summarize fertility preservation (FP) guidelines and consensus provided by medical facilities worldwide. Five reference databases (PubMed/Embase, China BioMedical Literature Database, ClinicalKey, Wanfang Data, and China Knowledge Resource Integrated) and 7 guideline databases (Guideline International Network, National Collaborating Centre for Women’s and Children’s Health, National Guideline Clearinghouse, The National Institute for Health and Care Excellence, Scottish Intercollegiate Guidelines Network, New Zealand Guideline Group, and Canadian Medical Association infobase) were searched. Official websites of societies were searched to find relevant guidelines and consensus, and guidelines and published systematic reviews and consensus were reviewed from inception through May 2021. A literature search was performed regarding guidance offered in professional facilities, and 304 records (including 4 in Chinese) of existing guidelines for full-text review were found. Moreover, 55 guidelines were identified after a manual search. The literature review demonstrated that FP guidance and options were unevenly distributed worldwide for women who wanted to post-pone pregnancy or had impaired fertility after gonadal toxicity. With promising cancer survival rates and diversified family decisions, more attention should be paid to the improvement and update of accessible guidelines and regulatory infrastructure to inform patients about the available options and empower them to make informed choices. Restrictions to such services can be gradually eased due to the efficacy and safety of certain FP techniques for the right candidates to initiate pregnancy conception.
