Infertility has become a significant problem worldwide. Multiple management options are available nowadays, which include intrauterine insemination (IUI), in vitro fertilisation (IVF), and intracytoplasmic sperm injection. IUI is one of the oldest and most popular methods. After >50 years since it was first used, IUI has evolved through various innovations but still struggles to find its place ...

In the field of reproductive medicine, assessment of sperm motility is a key factor for achieving successful artificial insemination, in vitro fertilization, or intracellular sperm injection. In this study, the motility of boar sperms was estimated using real-time imaging via confocal microscopy. To confirm this confocal imaging method, flagellar beats and whiplash-like movement angles were com...

The purposes of this study were to examine the relationship between male artificial insemination (AI) fertility and sperm acrosomal conditions assessed by new and conventional staining techniques and to identify possible reproductive dysfunctions causing low conception rates in AI using frozen-thawed spermatozoa with poor acrosomal conditions in Japanese Black bulls. We investigated individual ...

Assisted reproductive technologies (ART) have been used successfully in humans, domestic and laboratory species for many years. In contrast, our limited knowledge of basic reproductive physiology has restricted the application of ART in companion animal, non-domestic and endangered species (CANDES). Although there are numerous benefits, and in some cases a necessity, for applying ART for the re...

BACKGROUND Prediction models have been developed in reproductive medicine to help assess the chances of a treatment-(in)dependent pregnancy. Careful evaluation is needed before these models can be implemented in clinical practice. METHODS We systematically searched the literature for papers reporting prediction models in reproductive medicine for three strategies: expectant management, intrau...

Objectives: To determine if there is a difference in exclusive breastfeeding rates between mothers who conceived spontaneously compared with those who conceived using Artificial Reproductive Technology (ART). Study methods: A prospective cohort study (“All Our Babies”) of pregnant women was conducted in Calgary, Alberta, Canada from May 2008-May 2010. Participants completed three written questi...

OBJECTIVE To assess procreative outcomes for HIV-positive men and women with seronegative partners. DESIGN Systematic review and meta-analysis. SETTING Not applicable. PATIENT(S) Twenty-four studies with extractable data for HIV-serodiscordant couples undergoing intrauterine insemination (IUI) or in vitro fertilization (IVF). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) PRIMARY OU...

M any women and men, usually in the 20–50 age cohort, suffer from a condition that can be called prereproductive stress syndrome. The primary symptom is that these individuals have an urge to have children. Secondary symptoms, which are many and varied, can include a conviction that this urge is self evidently reasonable, and an illusion that others should help them in satisfying it. The syndro...

In vitro fertilization assays were performed to investigate their validity in evaluating artificial insemination (AI) bull fertility. A total of 1,532 oocytes, collected from ovaries at the abattoir, were subsequently used in a 4 x 6 x 2 factorial design: 4 doses of heparin added into the capacitation and fertilization medium (0; 0.05; 0.1 and 0.2 micrograms/ml), 6 different bulls with known on...
