Oocyte quality in assisted reproduction techniques

Minerva Endocrinology, 2022
The metaphase II (MII) oocyte is the mature female gamete, produced from a complex maturation process called oogenesis that starts in the first weeks of embryogenesis in the female embryo tract, continues during puberty, and is completed at fertilization with the spermatozoon. Oogenesis is closely related to folliculogenesis.

Dietary Patterns and The Outcomes of Assisted Reproductive Techniques in Women with Primary Infertility: A Prospective Cohort Study

International Journal of Fertility and Sterility, 2018
Background Infertility is one of the most common challenges that women in reproductive age would encounter today. The maternal nutritional status could be a determinant of oocyte quality and embryonic growth.

Is there a place for immunomodulation in assisted reproduction techniques?

Journal of Reproductive Immunology, 2004
We briefly review the history of the concepts of the materno foetal relationship, and the (various) rationales which have been used to justify lymphocyte alloimmunisation (LA) as a treatment for recurrent spontaneous abortion of putative immune origins.

Oxidative stress in an assisted reproductive techniques setting [PDF]

Fertility and Sterility, 2006
The manipulation of gametes and embryos in an in vitro environment when performing assisted reproductive techniques (ART) carries the risk of exposure of these cells to supraphysiological levels of reactive oxygen species (ROS). The main objective of this review is to provide ART personnel with all the necessary information regarding the development of

Assisted Reproduction: Techniques and Participants

2003
Oocytes of rabbits and mice, successfully cultured in vitro in the first half of the twentieth century, laid the foundation for assisted reproductive techniques decades later. In vitro fertilization (IVF) studies in rabbits resulted in the first birth of a normal offspring in 1959.

Assisted Reproductive Techniques

2006
There is good evidence in the literature in favour of intrauterine insemination (IUI) as the best first-line treatment and most cost-effective procedure in cases of mild and moderate male factor subfertility before starting more invasive and expensive techniques such as in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI).

Effects of assisted reproduction techniques on breastfeeding outcomes

The Journal of Maternal-Fetal & Neonatal Medicine, 2020
The aim of this study was to compare the breastfeeding outcome between those who conceived via assisted reproduction techniques (ART) and those who had spontaneous conception.This case-control study was conducted during a 2-year period between 2014 and 2016 in a tertiary healthcare center in Tehran, capital of Iran.

ASSISTED REPRODUCTIVE TECHNIQUES AND MALE INFERTILITY

Urologic Clinics of North America, 1994
For couples in whom improvement in spermatogenesis is not possible or is unsuccessful in producing conception, ARTs offer much promise. For mild to moderate male factor couples, IUI combined with superovulation is often the initial procedure employed. If unsuccessful, IVF or one of its variations should be considered.

Techniques for sperm recovery in assisted reproduction

Reproductive Medicine Review, 1999
During the past decade, few fields in medicine have changed as dramatically as reproductive medicine and the treatment of male infertility. Whereas previously only men with obstructive azoospermia were candidates for treatment, either through surgical reconstruction or sperm aspiration, now even men with nonobstructive azoospermia are able to achieve ...

Medical Techniques for Assisted Reproduction

1990
A couple having intercourse during the periovulatory period has no more than a one in five chance of conceiving a pregnancy that will result in the delivery of a mature infant. Since fertilization occurs in at least four of five cycles, this is an apparently poor rate of success.
