Abstract
 Aim: Low level laser therapy (LLLT) has been used in biostimulation of rat ovaries using a fibreoptic introduced directly through the vagina to deliver doses, which is new modality induction ovulation, compared with conventional medical ovulation clomiphene citrate and non-interventional controls. 
 Study design: A Prospective experimental study carried out from January 2014...

Background To evaluate the effect of metformin on ovulation and pregnancy rate in clomiphene citrate resistant women with polycystic ovary syndrome (PCOS). MaterialsAndMethods In this clinical trial each patient, regarding her previous resistance to Clomiphene, served as her own control. A total of 35 clomiphene citrate resistant PCOS patients, referring to Royan institute were studied. Clomiph...

BACKGROUND Sex steroid hormone fluctuations during the menstrual cycle are considered a risk factor for noncontact anterior cruciate ligament injuries. OBJECTIVE To determine whether self-reported menstrual history data can be used to accurately categorize menstrual cycle events using calendar-based counting methods. STUDY DESIGN Descriptive laboratory study. METHODS Seventy-three women c...

Our objectives were to estimate responses and genetic parameters for ovulation rate, number of fully formed pigs at birth, and other production traits following two-stage selection for increased ovulation rate and number of fully formed pigs. Eight generations of selection were practiced in each of two lines. One selection line was derived from a line that previously selected eight generations ...

In normal production practices, sows and gilts are inseminated at least twice during estrus because the timing of ovulation is variable relative to the onset of estrus. The objective of this study was to determine if a normal fertilization rate could be achieved with a single insemination of low sperm number given at a precise interval relative to ovulation. Gilts (n=59) were randomly assigned ...

Background: Currently clomiphene citrate is the first-line treatment to induce ovulation in women with polycystic ovarian syndrome (PCOS). Surgical therapy with laparoscopic ovarian drilling (LOD) may avoid or reduce the need for gonadotropins. Objective: To determine the effectiveness and safety of LOD compared with ovulation induction in subfertile women with clomiphene-resistant PCOS. Search...

Electrical stimulation of the anterior hypothalamus of the vole, Microtus agrestis, usually results in ovulation, whereas stimulation of areas in the posterior hypothalamus do not. Ovulation can also be elicited by injections of sheep median-eminence extracts, and by preparations ofsheep luteinizing hormone. Observations on the number of corpora lutea formed, and ripe Graafian follicles remaini...

approved: Redacted for Privacy Frank L. Moore To determine whether meiotic maturation of ovarian follicles, ovulation, and oviposition are influenced by male mating behaviors, female rough-skinned newts (Taricha granulosa) were captured prior to contact with males and maintained in simulated pond conditions. Females were either exposed to male courtship and inseminated or were isolated from mal...
