Are ultrasonic-guided follicular aspiration and flushing safe for the oocyte? 1987

S Lenz, and S Lindenberg, and C Fehilly, and K Petersen

Oocyte collection was carried out in 53 patients by ultrasonically guided abdominal puncture under local or epidural anesthesia. Follicles were aspirated and flushed two to six times using a syringe with culture medium. A total of 196 oocytes was collected and 84 of those (42.9%) were found in the flushes. Mechanical damage was observed in 5.1% of the oocytes. Cleavage rates in mature oocytes (157) after 48 hr in culture were similar in the aspirate group (56.5%) and in the flush group (54.2%). Ten clinical pregnancies were obtained, corresponding to a pregnancy rate of 18.9%.

UI	MeSH Term	Description	Entries
D009865	Oocytes	Female germ cells derived from OOGONIA and termed OOCYTES when they enter MEIOSIS. The primary oocytes begin meiosis but are arrested at the diplotene state until OVULATION at PUBERTY to give rise to haploid secondary oocytes or ova (OVUM).	Ovocytes,Oocyte,Ovocyte

D005307	Fertilization in Vitro	An assisted reproductive technique that includes the direct handling and manipulation of oocytes and sperm to achieve fertilization in vitro.

D006080	Ovarian Follicle	An OOCYTE-containing structure in the cortex of the OVARY. The oocyte is enclosed by a layer of GRANULOSA CELLS providing a nourishing microenvironment (FOLLICULAR FLUID). The number and size of follicles vary depending on the age and reproductive state of the female. The growing follicles are divided into five stages: primary, secondary, tertiary, Graafian, and atretic. Follicular growth and steroidogenesis depend on the presence of GONADOTROPINS.

D014463	Ultrasonography	The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.
