Sperm DNA Fragmentation: A New Guideline for Clinicians 
In light of these clinical case reports and recent scientific evidence, this review provides expert recommendations on SDF testing and examines the advantages and drawbacks of the clinical utility of SDF testing using Strength-Weaknesses-Opportunities-Threats (SWOT) analysis.

ART in Europe, 2016: results generated from European registries by ESHRE 
The 20th ESHRE report on ART and IUI shows a continuous increase of reported treatment numbers and MAR-derived livebirths in Europe. Being already the largest data collection on MAR in Europe, continuous efforts to stimulate data collection and reporting strive for future quality control of the data, transparency and vigilance in the field of reproductive medicine.

Use of a male antioxidant nutraceutical is associated with superior live birth rates during IVF treatment
The results of this large cohort study therefore support a positive association between men's use of the Menevit antioxidant during IVF treatment and live birth rates, especially in lean individuals.
Analysis of IVF/ICSI-FET Outcomes in Women With Advanced Endometriosis: Influence on Ovarian Response and Oocyte Competence 
Our data supported that advanced EMS has negative effect on cumulative clinical pregnancy per oocyte retrieval cycle, and AFC is an independent predictor, which is mainly caused by poor ovarian response associated with OMA per se or its surgery and the damage of peritoneal EMS to oocyte maturation.

Where has the quest for conception taken us? Lessons from anthropology and sociology 
The article concludes with thoughts on where future quests for conception might take us, and why IVF and other reproductive technologies are 'good to think with' in both the anthropology and sociology of reproduction.

General Information Regarding Pregnant Individuals and COVID-19 
The American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine (SMFM) have developed an algorithm to aid practitioners in assessing and managing pregnant women with suspected or confirmed COVID-19

Population implications of cessation of IVF during the COVID-19 pandemic 
The study demonstrated that the discontinuation of fertility treatment for even 1 month in the USA could result in 369 fewer women having a live birth, due to the increase in patients' age during the shutdown. As a result of reductions in cumulative live birth rate, more cycles may be required to overcome infertility at individual and population levels.

A Shift in Glycerolipid Metabolism Defines the Follicular Fluid of IVF Patients with Unexplained Infertility 
Potential lipid biomarkers for pregnancy outcomes showed a highly discriminative abundance in the FF of unexplained infertility patients. Lipid abundance distinguished IVF patients with unrecognized infertility and provided a potential means for the evaluation of female fertility.
Endometriosis Lowers the Cumulative Live Birth Rates in IVF by Decreasing the Number of Embryos but Not Their Quality 
The implantation rate and the live birth rate per cycle were comparable between the two groups, but the cumulative live births rate was significantly lower in in the endometriosis group (32.1% v 50.7%, as a consequence of the lower number of frozen embryos.

Glutathione-dependent enzymes in the follicular fluid of the first-retrieved oocyte and their impact on oocyte and embryos in polycystic ovary syndrom 
Also all of the mean measured levels were significantly higher in the FF of the MII oocytes compared to that of oocytes with lower grades (p = 0.012, 0.006 and 0.012, respectively). The mean GPX activity and GSH levels were significantly higher in the serum (p = 0.016 and 0.012, respectively) and FF (p = 0.001 for both) of the high-quality grade I embryos.
The Role of the Epididymis and the Contribution of Epididymosomes to Mammalian Reproduction 
Importantly, we also discuss specific characteristics and roles of epididymal-derived exosomes (epididymosomes) in establishing sperm competency within the intricate process of reproduction. This review suggests that an increasing body of evidence is working to develop a complete picture of the role of the epididymis in male reproduction, offspring health, and disease susceptibility.

Cryopreservation and IVF in the time of Covid-19: what is the best good tissue practice (GTP)? 
Examine good tissue practices as relates to in vitro fertilization, biopsying, and vitrificationto compare current knowledge of ova, sperm, and embryos as vectors for disease transmission as it relates to our current knowledge regarding the SARS-CoV-2 virus.Unknown risks relating to the SARS-CoV-2 virus and sperm, ova, and embryos necessitate a reexamining of how human IVF is performed.

Human sperm uses asymmetric and anisotropic flagellar controls to regulate swimming symmetry and cell steering 
Flagellar waves are generated by thousands of asymmetric molecular components: yet, paradoxically, forward swimming arises via symmetric side-to-side flagellar movement. This led to the preponderance of symmetric flagellar control hypotheses. However, molecular asymmetries must still dictate the flagellum and be manifested in the beat.
Assessment of SARS-CoV-2 in human semen-a cohort study 
A mild COVID-19 infection is not likely to affect testis and epididymis function, whereas semen parameters did seem impaired after a moderate infection. SARS-CoV-2 RNA could not be detected in semen of recovered and acute COVID-19-positive men. This suggests no viral transmission during sexual contact and assisted reproductive techniques, although further data need to be obtained.

scRNA-seq Profiling of Human Testes Reveals the Presence of the ACE2 Receptor, A Target for SARS-CoV-2 Infection in Spermatogonia, Leydig and Sertoli 
The results indicate that ACE2 is predominantly enriched in spermatogonia and Leydig and Sertoli cells. Gene Set Enrichment Analysis (GSEA) indicates that Gene Ontology (GO) categories associated with viral reproduction and transmission are highly enriched in ACE2-positive spermatogonia, while male gamete generation related terms are downregulated

SARS-CoV-2 and human reproduction: An open question 
SARS-CoV-2 is believed to become a long-term problem. This being so, fertility and ART treatments are resuming in a climate of uncertainty and without crystal clear information about the safety of male and female gametes.
