Somatic cell count and type of intramammary infection impacts fertility from in vitro produced embryo transfer.

Theriogenology
The objective of this study was to assess the impact of mastitis-causing bacteria and somatic cell count (SCC) on pregnancy per embryo transfer (P/ET) in Holstein-Gir crossbred (Girolando) lactating dairy cows. Cows (n = 1397) were subjected to a tim...

Fertility of lactating dairy cows treated with gonadotropin-releasing hormone at AI, 5 days after AI, or both, during summer heat stress.

Theriogenology
Objectives of this experiment were to evaluate pregnancy per AI (P/AI) and progesterone (P4) concentrations after AI of lactating dairy cows under heat stress conditions treated with 100 μg gonadotropin-releasing hormone (GnRH) at AI, 5 d after AI, o...

Caloric restriction and IGF-I administration promote rabbit fecundity: Possible interrelationships and mechanisms of action.

Theriogenology
The aim of these in vivo and in vitro studies was to examine the influence of caloric restriction (CR), and the administration of insulin-like growth factor (IGF-I), on rabbit fecundity and to understand the interrelationships between CR and IGF-I, a...

Optimization of post-cervical artificial insemination in gilts: Effect of cervical relaxation procedures and catheter type.

Theriogenology
Post-cervical (pC) artificial insemination (AI) has been successfully developed for application in multiparous sows, although it has proved problematic in gilts. This study analyzes the use of pC-AI in gilts by two experiments. In the first experimen...

Progesterone supplementation in the early luteal phase after artificial insemination improves conception rates in high-producing dairy cows.

Theriogenology
This study examines the possible effects on the reproductive performance of high-producing dairy cows of progesterone (P4) given in the early luteal phase (1.55 g of P4), from Days 3 to 5 post-artificial insemination (AI) as compared with the time of...

Salvage robot assisted radical prostatectomy: A propensity matched study of perioperative, oncological and functional outcomes.

European journal of surgical oncology : the journal of the European Society of Surgical Oncology and the British Association of Surgical Oncology
BACKGROUND: To report the perioperative, functional and oncological outcomes of salvage robot-assisted laparoscopic prostatectomy (s-RARP) in a propensity score-matched analysis.

Effect of uterine size on fertility of lactating dairy cows.

Theriogenology
There are multiple reasons for reduced fertility in lactating dairy cows. We hypothesized that one cause of reduced fertility could be the overall size of the reproductive tract, particularly the uterus, given well-established uterine functions in ma...

Minimization of curative surgery for treatment of early cervical cancer: a review.

Japanese journal of clinical oncology
Surgery is effective and useful for curative treatment of patients with early invasive cervical cancer, yet minimization of surgical procedures provides many additional advantages for patients. Because the mean age of patients diagnosed with cervical...

Designing of an artificial neural network model to evaluate the association of three combined Y-specific microsatellite loci on the actual and predicted postthaw motility in crossbred bull semen.

Theriogenology
The freezing of bull semen significantly hamper the motility of sperm which reduces the conception rate in dairy cattle. The prediction of postthaw motility (PTM) before freezing will be useful to take the decision on discarding or freezing of the ge...

Visualized hysteroscopic artificial intelligence fertility assessment system for endometrial injury: an image-deep-learning study.

Annals of medicine
OBJECTIVE: Asherman's syndrome (AS) is a significant cause of subfertility in women from developing countries. Over 80% of AS cases in these regions are linked to dilation and curettage (D&C) procedures following pregnancy. The incidence of AS in pat...
