Ovarian hyperstimulation syndrome following ovum pick-up procedure: A case study

Medicover Journal of Medicine
Advances in assisted reproduction technologies (ARTs) have increasingly allowed infertile women to access such treatment modalities. As controlled ovarian hyperstimulation (COH) is a routine protocol to generate a sufficient number of follicles during in

Long term effect of Ovum Pick-up in buffalo species

Animal Reproduction Science, 2011
The aim of this study was to evaluate the effect of an Ovum Pick-up (OPU) treatment carried out for 9 months in buffalo (Bubalus bubalis) species. Eight pluriparous non-lactating buffalo cows underwent OPU for 9 months. Recovered cumulus enclosed oocytes (COCs) were classified and COCs suitable for in vitro embryo production (IVEP) were in vitro ...

Perurethral ultrasound-guided ovum pickup

Journal of In Vitro Fertilization and Embryo Transfer, 1988
Either a percutaneous-transvesical, a transvaginal, or a perurethral-transvesical approach can be used for oocyte recovery under ultrasound guidance in an in vitro fertilization and embryo transfer program. After having experienced these three different approaches in our program, we preferentially used the perurethral-transvesical approach as our ...

Ovum pick up, in vitro embryo production, and embryo transfer as value-added theriogenology service in miniature Hereford cattle operation

Clinical Theriogenology
Goal was to provide evidence for adopting assisted reproductive technologies (ART), ovum pick up (OPU), in vitro embryo production (IVP), and embryo transfer (ET) in small beef cattle operations as value-added service.

Ovum Pick-Up (OPU) in Cattle: An Update

2020
The technique of ultrasound-guided transvaginal follicular aspiration for ovum pick-up (OPU) is a non-invasive procedure for recovering oocytes from antral follicles in live animals, especially in cows and mares. It was originally developed for assisted reproduction in the human species to assist infertility and was used for the first time in cattle in

159 TECHNIQUES FOR OVUM PICK-UP IN GONADOTROPIN-TREATED ALPACAS

Reproduction, Fertility and Development, 2007
The objective of the present study was to evaluate the quantity and quality of oocytes collected when using 2 methods for ovum pick-up and 2 different regimens for ovarian stimulation in live alpaca donors. Thirty-four non-pregnant female alpacas of 3 to 5 years of age maintained at 4100 m elevation in southern Peru were randomly distributed into 4 ...

Repeated endoscopic ovum pick-up in hormonally untreated ewes: a new technique

Theriogenology, 1997
Multiple ovulation and embryo transfer (MOET) are cumbersome and may not be used in all animals. An alternative method for obtaining embryos is to harvest ova and subject them to in vitro maturation/fertilization (IVM/IVF). We tested a modified endoscopic technique designed to allow repeated recovery of oocytes from donor ewes without any hormonal ...

P-750 Is maximalization of the ovum pick-up (OPU) procedure beneficial for the outcome of assisted reproductive technology (ART) cycles?

Human Reproduction
Is aspiration of more oocytes than the antral follicle count (AFC) beneficial for the current (pregnancy/live birth rates) and future products of an ART cycle?

Ovum Pick‐up in Dairy Heifers: Does it Affect Animal Well‐being?

Reproduction in Domestic Animals, 2007
ContentsThe aim of the present study was to assess the effects of the ovum pick‐up (OPU) technique on animal well‐being. Eight dairy heifers were subjected to 4 months of twice‐weekly OPU. The physiological response to OPU was recorded in four heifers at two sessions, at the beginning (time 1) and at the end (time 2) of the 4‐month period.

Association between Ovum Pick-Up (OPU) frequency and stressrelated hormone concentrations in Holstein heifer oocyte donors

Genetics and breeding of animals
Purpose : to determine whether transvaginal ultrasound-guided ovum pick-up (OPU) procedures influence the concentrations of stress-associated hormones in the serum of Holstein heifer oocyte donors, and to assess whether the intensity and duration of ...
