This is a case series reporting live births following in vitro fertilization (IVF) after fertility-sparing surgery in patients with borderline ovarian tumors (BOTs). Seventeen patients, in whom fertility-sparing surgery for BOTs followed by IVF was performed from July 1, 2011 to September 30, 2017, in our IVF center, were included. Here we retrospectively present their BOT characteristics and clinical outcomes of assisted reproduction technology (ART) and then discuss the literature on management of patients with BOTs after fertility-sparing surgery. The study sample of 17 patients started IVF-assisted reproduction within ...

ConclusionsOverall, there was no significant difference in birth defects resulting from IVF ‐ICSI with autologous or donor oocytes. The births resulting from IVF‐ICSI pregnancies did not tend to have a higher rate of birth defects a compared with natural conceptions. The differences in the prevalence of certain birth defects (cardiovascular or central nervous system) reported in IVF‐ ICSI pregnancies may be due to improved surveillance modalities and early detection in pregnancies following IVF‐ICSI. A study with larger number of sample size will give us better understanding of the prevalence of reported incidence in this study.

ConclusionGopc−/− mice have defective acrosome and manchette. The manchette is involved in the transport of proteins through the cytoplasm and the nucleus. Considering that the GCNF protein is normally transported to the acrosome and the nucleus, it can be thought that transport deficiencies inGopc−/− mice are responsible for the increased expression of this protein.

ConclusionScientific evidence supports the use of mucuna and ashwagandha as phytotherapics for improving serum T concentrations and semen parameters. Despite inconclusive evidence for use of tribulus as a T booster, it may provide advantageous effects on sperm parameters in men with idiopathic infertility. Nutraceutical strategies and some phytotherapics may also be effective to promote prostate health. Popular foodstuffs (onion, garlic, and tomato), nutraceutical agents (pollen extract and beta-sitosterols), and herbal medicines (Pygeum africanum and Urtica dioica) are rational approaches.Graphical abstract
