  • 简介:反应的氧种类(ROS)的过多的数量引起氧化应力的一个状态,它导致精子膜类脂化合物peroxidation,DNA损坏和apoptosis,导致减少的精子生存能力和活动性。ROS的提高的层次是自发的男因素不孕的一个主要原因,它是今天的一个逐渐地普通的问题。Lycopene,所有类胡萝卜素的大多数有势力汗衫氧quencher,因为它的抗氧化剂性质,是为男不孕的一种可能的处理选择。由反应与并且抵销自由激进分子,lycopene能减少氧化应力的发生并且这样,减少将不那样被施加在精子身上的损坏。lycopene可以在睾丸经由nonoxidative机制有另外的有益的效果,这被要求,例如差距连接通讯,基因表示的调整,房间周期和immunoenhancement的规定。在人和动物上进行的各种各样的lycopene补充研究在减轻男infertility—显示出有希望的结果;当精子计数和生存能力,和一般免疫被增加时,类脂化合物peroxidation和DNA损坏被减少。这些参数的改进在氧化应力显示减小,并且这样精子对氧化损坏不太脆弱,它增加使肥沃的一个正常精子的机会卵。人的试用每天与lycopene的4-8mg的补充在精子参数和怀孕率报导改进3-12月了。然而,进一步详细说明了,广泛的研究仍然被要求为男不孕作为一个处理决定剂量和lycopene的实用性。

  • 简介:AbstractObjective:This study aimed to screen for novel mutations in ACTL7A and expand the spectrum of known mutations responsible for recurrent fertilization failure.Methods:Whole-exome sequencing was performed on samples from couples who experienced recurrent assisted reproductive technology failure and visited the General Hospital of Ningxia Medical University. Western blotting and quantitative Real-time PCR were used to investigate the effects of the mutation on HEK293T cells.Results:Samples from 12 couples with total fertilization failure or poor fertilization (fertilization rate <20%) were subjected to whole-exome sequencing, and a novel homozygous protein-truncating mutation (c. 1101dupC, p. S368Qfs*5) in ACTL7A was identified in a patient with recurrent poor fertilization. The mutant resulted in a truncated protein as well as decreased protein expression level in HEK293T cells.Conclusions:Our findings expand the mutational and phenotypic spectrum of ACTL7A, thus providing a potential diagnostic marker for fertilization failure due to male factors.

  • 简介:AbstractInfertility seriously endangers the reproductive health of women at childbearing age. It is defined as the failure to achieve successful pregnancy after 1 year or more of regular unprotected intercourse. Broadly defined, infertility includes two aspects - failure to conceive or have a live birth. This guideline only addressed content relevant to the former. It was proposed by the gynecological endocrine group of the Chinese Society of Obstetrics and Gynecology, Chinese Medical Association, based on relevant guidelines of the World Health Organization, the American Society for Reproductive Medicine, the National Institute for Health and Clinical Excellence, as well as the clinical practice in China. The guideline was reviewed by experts and doctors from medical institutions at all levels, which is applicable to the diagnosis of infertility by physicians in obstetrics, gynecology, and andrology at various medical institutions nationwide.

  • 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:AbstractAlthough considerable advances have been made in the field of assisted reproductive technology (ART), millions of couples still suffer from infertility and miscarriage. In a large number of cases, the etiology of these common reproductive failures remains unknown. However, the significance of autoantibodies in infertility and miscarriage has sparked extensive interest because of their pleiotropic roles in disrupting normal pregnancy. This review discusses the pleiotropic roles of a series of autoantibodies in infertility and miscarriage. A brief recapitulation of how the autoantibodies interfere with ART outcomes and treatments for this type of idiopathic infertility or miscarriage is also provided. While several disputes remain to be resolved, further studies employing better designs and larger sample sizes are required in view of the therapeutic potential of autoantibody inhibitors and the future of contraceptive vaccines.

  • 简介:AbstractThere is currently no universally accepted unified diagnostic standard for infertility treatment and maternity protection related to polycystic ovary syndrome (PCOS) worldwide, and the treatment options vary greatly. 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:AbstractBoth fatty acids (FAs) and calcium ions play important roles in contraceptive cycles via several systems. Polyunsaturated FAs (PUFAs) act as precursors for prostaglandin production and can alter the expression of numerous crucial catalysts that are involved in prostaglandin and steroid digestion. Lipids are essential components of cell membranes. A diet rich in PUFAs enhances sperm motility and viability. It also improves testis development and spermatogenesis in several domesticated animal species. Increased PUFA content in spermatozoa increases plasma membrane fluidity, which is important for fertilization. However, the major drawback of high dietary PUFA intake is that it increases the levels of reactive oxygen species in the body. An increase in reactive oxygen species levels markedly affects fertility. Calcium is an important component that acts as an intra-cellular secondary messenger and plays an important role in some of the physiological processes that occur in male gametes. Some of these processes include spermatogenesis, sperm motility, capacitation, acrosome response, and fusion of gametes. These processes are associated with calcium influx through ion protein channels. Dietary fat intake is associated with increased intestinal calcium absorption. In this review, we discuss the impact of lipids, particularly PUFAs and monounsaturated FAs, and calcium ions on male reproduction, along with their effects on each other.
