Zinc Levels in Seminal Fluid in Infertile Males and its Relation with Serum Free Testosterone
Introduction: The role of zinc is critical to reproduction potential. Seminal zinc is thought to be derived almost exclusively from prostatic secretions. Sperm motility is significantly influenced by zinc. Zinc deficiency has been linked with male sterility and subfertility.
Aim: To assess the influence of seminal plasma zinc on seminogram charact...
The zinc spark is an inorganic signature of human egg activation
Egg activation refers to events required for transition of a gamete into an embryo, including establishment of the polyspermy block, completion of meiosis, entry into mitosis, selective recruitment and degradation of maternal mRNA, and pronuclear development. Here we show that zinc fluxes accompany human egg activation. We monitored calcium and zinc dynamics in individual ...
The role of vitamin D in reproductive dysfunction in women – a systematic review
Vitamin D is essential for the proper functioning of the human body. There is also evidence of its strong association with fertility problems in women. This review aims to evaluate the relationship between vitamin D and diseases affecting women’s fertility (polycystic ovarian syndrome (PCOS), uterine leiomyomas and endometriosis), and in vitro fertilizatio...
The influence of ginger (Zingiber officinale) on human sperm quality and DNA fragmentation: A double-blind randomized clinical trial
Background: Although the effectiveness of ginger as an antioxidant agent has been exploited, little human research has been conducted on its activity on male reproductive functions. Objective: This study was designed to investigate the effects of ginger (Zingiber
officinale) on sperm DNA fragmentation (SDF) ...
The effects of tomato juice on male infertility
This study aimed to investigate the effects of tomato juice consumption on seminal plasma lycopene levels and sperm parameters in infertile men. Methods and Study Design: Subjects were male infertility patients with poor sperm concentration (<20×106/mL) and/or motility (<50%). Following a fourweek observation period, subjects were randomly assigned among three groups: a tomato juice ...
The Deep Correlation between Energy Metabolism and Reproduction: A View on the Effects of Nutrition for Women Fertility
In female mammals, mechanisms have been developed, throughout evolution, to integrate environmental, nutritional and hormonal cues in order to guarantee reproduction in favorable energetic conditions and to inhibit it in case of food scarcity. This metabolic strategy could be
an advantage in nutritionally poor environme...
Synergetic Effects of K, Ca, Cu and Zn in Human Semen in Relation to Parameters Indicative of Spontaneous Hyperactivation of Spermatozoa
We have observed that sperm quality parameters indicative of spermatozoa hyperactivation such are lower “linearity” and “straightness”, and as showed by this research “elongation”, were more pronounced in patients with normal spermiogram compared to the group of men
with reduced sperm ...
Serum levels of lycopene, beta-carotene, and retinol and their correlation with sperm DNA damage in normospermic and infertile men
Background: Oxidative stress in reproductive system leads to sperm DNA damage and sperm membrane lipid peroxidation and may play an important role in the pathogenesis of male infertility, especially in idiopathic cases. Antioxidants such as carotenoids function against free radical damages. Objective: The aim of ...
