Data from a British national cohort of women born in 1946 were used to investigate the hypothesis that the rate of depletion of oocyte numbers is associated with the age at which a woman reaches the inception of the perimenopause. Menopausal status was obtained using an annual questionnaire, sent to the cohort since the age of 47 years, and risk factor information from contacts with the survey ...

This experiment was designed to test the following two hypotheses: (1) beef cows unilaterally ovariectomized will ovulate more viable ova at the first post-operative estrus than intact animals when all are given human chorionic gonadotropin (HCG) at estrus, and that (2) this result is more likely if the CL-containing ovary is not removed. Thirty-five Angus and Anguscross cows were assigned rand...

Nodular sclerosing Hodgkin disease stage IV according to the Ann Arbor classification was diagnosed in a 30-year-old nulliparous woman. Because management required the use of a chemotherapy regimen with a high risk of secondary infertility, ovarian cryopreservation was realized by single-site laparoscopic unilateral oophorectomy. The single-site approach can limit aesthetic consequences in youn...

In this study we evaluated, in 10 sevoflurane-anesthetized pigs undergoing abdominal surgery, different techniques for measuring autonomic nervous system (ANS) activity: ANSiscope index, spectral analysis of heart-rate variability, hemodynamic variables, and plasma catecholamines and cortisol levels. Animals underwent a 120-min anesthesia during which unilateral ovariectomy was performed. Cardi...

Massive hemorrhagic ascites (4470 mL, range 1-10 L) in women with endometriosis is a rare condition occurring predominantly in black women. Of the 43 case reports published, 42 are compatible with the hypothesis that the hemorrhagic ascites is predominantly a consequence of excessive ovarian transudation similar to a Meigs syndrome. Indeed, bilateral ovariectomy cures the condition without recu...

The effectiveness of laparoscopic ovarian drilling for treatment of anovulation in polycystic ovarian syndrome (PCOS) has been proved. The role of ovarian surgery in the treatment of symptoms related to hyperandrogenaemia, such as hirsutism and acne, has been less clear. This review sought to evaluate the effectiveness of ovarian surgery in the treatment of non-infertility symptoms related to P...

Plasma follicle-stimulating hormone (FSH) was evaluated in gilts from two studies in which ovulation rate was increased through direct selection for number of corpora lutea (CL) to determine whether selection for ovulation rate affected FSH secretion during prepubertal development. In the first study, 76 control and 110 selected gilts of University of Nebraska gene pool lines were bled twice du...
