Comparative Evaluation of Follicular Flushing Frequency and Scraping Time During Ovum Pick-Up in Mares: Effects on Oocyte Recovery Rate and Technical Considerations. [PDF]

Reprod Domest Anim
ABSTRACT Transvaginal ultrasound‐guided follicular aspiration or ovum pick‐up (OPU) has become the standard technique for oocyte collection in mares for intracytoplasmic sperm injection (ICSI). Although repeated follicular flushes and wall scraping are commonly used to improve oocyte recovery rate (ORR), the relative contribution of each remains ...

Asthma and Infertility: A Prospective Case-Control Study on Pregnancy and Live Birth Rates in Women With Asthma Undergoing Assisted Reproduction. [PDF]

Clin Respir J
This large prospective cohort study shows no impact of asthma on pregnancy and live birth rate among infertile women undergoing assisted reproduction. ABSTRACT Background Previous studies have suggested a negative impact of asthma on fertility, and it has been hypothesized that the underlying inflammation is playing an important role.

Possibility of Repeated Use of Elite Donor Cows for Mass Production of OPU-Derived Emb

Journal of Animal Reproduction and Biotechnology, 2015
This study was designed to know the possibility in repeat uses of elite donor cows for getting mass production of OPU-derived embryo production (OPU-IVP). Ultrasound transvaginal ovum pick-up (OPU) performed in 6 Korean native cows was aged 4 to 10 years
