REVIEW
Youn Jeong Lee, Kyong Wook Yi
Stem cells are undifferentiated cells capable of self-renewal and differentiation into various cell lineages. Stem cells are responsible for the development of organs and regeneration of damaged tissues. The highly regenerative nature of the human endometrium during reproductive age suggests that stem cells play a critical role in endometrial physiology. Bone marrow-derived cells migrate to the uterus and participate in the healing and restoration of functionally or structurally damaged endometrium. This review summarizes recent research into the potential therapeutic effects of bone marrow-derived stem cells in conditions involving endometrial impairment...

REVIEW
Gi Young Kim
In an age when a small quantity of sperm can lead to pregnancy through in vitro fertilization or intracytoplasmic sperm injection, selecting healthy sperm is important. Sperm DNA fragmentation (SDF) is known to be higher in infertile men. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling (TUNEL) and the alkaline comet test are SDF tests that directly measure DNA damage and have shown closer correlations with assisted reproduction results than indirect tools such as the sperm chromatin structure assay or the sperm chromatic dispersion test...

REVIEW
Ahmed T Alahmar
It has been estimated that approximately 15% of reproductive-age couples suffer from infertility. Male factors contribute to almost half of infertility cases, and in many patients the underlying cause of oligoasthenoteratozoospermia is unknown. Accumulating evidence suggests that oxidative stress plays a role as a contributing factor to male infertility, and reactive oxygen species have been shown to impair sperm function and motility and to damage sperm membrane and DNA. Therefore, this review explored the evidence provided by studies published from 2002 to 2017 on the impact of oral antioxidants (vitamin C, vitamin E, L-carnitine, coenzyme Q10, zinc, selenium, and pentoxifylline) on seminal fluid parameters in men with idiopathic oligoasthenoteratozoospermia...
