Assisted reproductive technology (ART) is a common treatment of choice for many couples facing infertility issues, be it due to male or female factor, or idiopathic. Employment of ART techniques, however, come with its own challenges as the in vitro environment is not nearly as ideal as the in vivo environment, where reactive oxygen species (ROS) build-up leading to oxidative stress is kept in ...

We report a case of polycystic ovary syndrome and prolonged infertility in which endometrial intraepithelial neoplasia was reversed with high dose progesterone therapy. Spontaneous conception after failure of assisted reproductive techniques highlights the role of endometrial receptivity.

Maternal age effects on parenting and family outcomes are of increasing interest because of the demographic shift toward older maternal age at first birth. Maternal age is also of interest because of the greater use of assisted reproductive techniques (ART) to bypass age-related infertility in couples trying to conceive late in the reproductive life cycle of the woman. The aim of the present st...

Venous thromboembolism (VTE) affects 0.1-0.3% people each year. The risk of VTE following gynecological surgery and invasive procedures is well established and presents one of the major challenges in gynecological practice. Moreover, commonly use assisted reproductive techniques (ART) are reported to increase the risk of VTE. Despite continued efforts to reduce its incidence, postoperative VTE ...

The growing popularity of vasectomy as a primary form of birth control has also created an increasing demand for vasectomy reversal (VR). The advent of IVF with intracytoplasmic sperm injection after sperm retrieval has given couples an alternative to traditional VR. Although VR remains the most cost-effective and natural way to conceive after vasectomy, competing interests and market pressures...

OBJECTIVE From early gestation the human trophoblast secretes large amounts of inhibin A and activin A, and their measurement provides a value for predicting the outcome in women who become pregnant after assisted reproductive techniques. The aim of the study was to investigate the putative role of maternal serum inhibin A and activin A levels as markers of a viable trophoblast in women who mis...

In the past decade, assisted reproductive technologies (ART) such as oocyte transfer, intracytoplasmic sperm injection (ICSI), and nuclear transfer (cloning) have become effective enough for clinical use. ART such as oocyte transfer and ICSI allow production of foals from mares that cannot provide an embryo by standard embryo-transfer procedures. For the equine practitioner, application of ART ...

OBJECTIVE: To compare the pregnancy outcome between high-order multiple and twin pregnancies. DESIGN: Matched-pair retrospective analysis. SETTING: University teaching hospital, Hong Kong. PATIENTS: Patient records from 38 high-order multiple pregnancies that were delivered over a period of 15 years, and those from matched twin pregnancies. MAIN OUTCOME MEASURES: Obstetric and perinatal outcome...

Ovarian pregnancy is a rare event occurring in 1-3% of all ectopic pregnancies. Increased reporting might be due to the wider use of intra-uterine devices, ovulatory drugs and assisted reproductive techniques. Though ovarian pregnancy has a distinct pathology, it can be a source of clinical and intraoperative diagnostic difficulty. We report two cases of ovarian pregnancy - one primary and one ...

The relation of thyroid autoimmunity to miscarriage is an important issue that has attracted the interest of many investigators. A number of papers have been published so far, which include healthy women, women with recurrent miscarriage and those undergoing assisted reproductive techniques. Most studies have shown a significant positive association between the presence of thyroid autoantibodie...
