We tested to see if semen collection interferes with fertility in naturally fertile pairs of cranes. We used 12 naturally fertile, Florida sandhill crane (Grus canadensis pratensis) pairs for this study, 6 control and 6 experimental. All pairs had previously produced fertile eggs. Semen was collected on Tuesday mornings and Friday afternoons from 26 February 1993 to 4 June 1993. We used standar...

A NEW TECHNIQUE FOR THE STUDY OF DROSOPHILA EGGS AND LARVAE WHILE carrying on hybridization experiments on two subspecies of Drosophila virilis it was suggested to the writer by Dr. A. H. Sturtevant that egg counts be made. In attempting to improve on the present technique of egg collection it was discovered that a fly will readily deposit her eggs through cloth mesh onto the proper medium. To ...

Introduction: The appropriate ultrasound technique to assess the maternal cervical length in women at low risk of preterm birth is yet to be established. This study aimed to determine the accuracy of different ultrasound approaches for measuring the maternal cervix in patients between 17 and 22 weeks gestation. Methods: The prospective study recruited 50 patients who were at a low risk of prete...

Nuclear transfer stem cells hold considerable promise in the field of regenerative medicine and cell-based drug discovery. In this study, a total of 29 oocytes were obtained from three young (20-24 years old) reproductive egg donors who had been successful in previous cycles. These oocytes, deemed by intended parents to be in excess of their reproductive needs, were donated for research without...

Polycystic ovary syndrome is an accumulation of endocrine changes that associates oligo-amenorrhea, obesity, hirsutism, androgen excess and resistance to insulin. Ovarian drilling can be done through classical laparoscopy and by transvaginal hydrolaparoscopy minimally invasive surgical method. We performed a meta-analysis of eight studies conducted between 2003-2011, which include a total of 35...

SETTING Private, academically affiliated IVF center. PATIENT(S) Women undergoing assisted reproductive technologies (ART) and having a diagnosis of OHSS. INTERVENTION(S) Management of OHSS with hospitalization or ...

OBJECTIVE To examine the prevalence, incidence, persistence, and resolution of ovarian abnormalities using serial transvaginal ultrasonography. METHODS A group of 39,337 women in the University of Kentucky Ovarian Cancer Screening Program were monitored with 221,576 baseline and interval transvaginal ultrasonography. RESULTS The transvaginal ultrasonogram was normal for first and all subseq...

BACKGROUND Pioneers in natural orifice transvaginal cholecystectomy are in search of an approach that uses less percutaneous assistance. The approach must be safe and affordable. The authors present a successful cholecystectomy using a technique of transvaginal operative laparoscopy with no abdominal ports. METHODS A 24-year-old female patient with gallbladder lithiasis underwent a natural or...
