Induction ovulation

P S Baruselli, R M Ferreira, M F Sá Filho, G A Bó
The aim of this review is to compare the performance of different reproductive programs using natural service, estrus synchronization treatment before natural service (timed natural breeding (TNB)), artificial insemination (AI) following estrus detection and timed artificial insemination (TAI) in beef herds. It is well known that after parturition the beef cow undergoes a period of anestrous, when they do not exhibit estrus, eliminating the opportunity to become pregnant in the early postpartum by natural mating or by AI after detection of estrus...

The ovarian hyperstimulation syndrome (OHSS) is an iatrogenic syndrome, which may, infrequently, become severe and evenly fatal. Until the last decade, the worldwide popularity of assisted reproductive technology (ART) and ovulation induction/controlled ovarian hyperstimulation employed in ART for either in vivo fertilization or in vitro fertilization, in the last two decades, has been accompanied by an increase in the cases of OHSS. In the last decade, the substitution of the human chorionic gonadotropin trigger with the gonadotropin-releasing hormone agonist trigger has decreased the incidence of this syndrome but did not eliminate it completely...

In this paper, 153 infertile women undergoing induction of ovulation at an academic tertiary care centre were included in a cross-sectional study. Serum Vitamin D level was measured and the rate of clinical pregnancy (defined as a sonographic presence of FHR of an intrauterine gestational sac) and patient and cycle parameters were determined. The results showed that a correlation exists between endometrial thickness as well as the number of antral follicles and replete level of Vitamin D. Interestingly, the median level of these two parameters was of upmost level in the most replete tertile of serum Vitamin D level...

Obesity is one of the leading global risk factors for poor health. With the increasing prevalence of obesity over last two decades in gulf countries, there has also been an increase in the infertile population [1]. In 2016, WHO [1] reported that 47.8% of women in Qatar were obese. Few studies of the impact of body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) on treatment outcome in women experiencing infertility have been performed in the gulf region.

A lower number of metaphase II oocytes eligible for vitrification after controlled stimulation in cancer patients has recently been reported, suggesting that cancer may impair the dynamics and quality of follicular growth. In this prospective, non-interventional study, the pattern of follicular growth and oocyte cohort after ovarian stimulation in cancer patients was analysed. Ninety cancer patients, recruited before starting chemotherapy, were compared with 180 time- and age-matched healthy controls undergoing intracytoplasmic sperm injection...

Low-dose, step-up gonadotropin is the treatment of choice for women with PCOS who have not conceived after anti-estrogen treatment, and as an effective alternative to pulsatile GnRH in women with hypogonadotropic hypogonadism (HH). There has been, however, no large-scale, comparative study between the two groups using low-dose gonadotropins. Here we performed a retrospective, comparative analysis, in a single clinic database, of efficacy and safety of induction of ovulation using low-dose gonadotropins in 364 Women with PCOS and 80 women with HH...

GnRH antagonists have several clinical applications in prostate cancer, regulation of ovulation induction in females, breast cancer, male contraception and others. Antagonists differ from natural GnRH decapeptide in having five or more amino acid substitutions. Whereas most of antagonists are available as subcutaneous (SC) formula for injection, some are formulated as a depot formulation for sustained release (e.g. Cetrarelix, Degarelix). Systemic delivery of cetrorelix acetate by intratracheal route can be achieved using dry powder for inhalation of adhesive mixture when the powder deposition reaches stage four...

Introduction: Regulatory agencies recommend a stepwise approach for demonstrating biosimilarity between a proposed biosimilar and reference biological product emphasizing for functional and structural characterization to trace if there is any difference which may impact safety and efficacy. We studied the comparative structural and biological attributes of recombinant human chorionic gonadotropin (rhCG), SB005, with reference product, Ovidrel ® and Ovitrelle ® . Recombiant hCG was approved in 2000 by the US Food and Drug Administration for the induction of final follicular maturation, early luteinization in infertile women as part of assisted reproductive technology program...
