Active clinical trials for "Infertility"

Endometrin is a progesterone supplement prescribed during in vitro fertilization (IVF) for preparation for embryo transfer. The usual dose of Endometrin is 100 mg two to three times per day in the form of an effervescent tablet to be inserted vaginally. The purpose of this research project is to evaluate the dose response of the Endometrin when determined based on the blood level of progesterone on the day of the FET. According to the literature, a predefined level of progesterone in the blood should be reached in order to have favorable conditions for pregnancy. The hypothesis being that a woman with low progesterone levels would benefit from a dose of Endometrin of 600 mg (200 mg 3x/day) to decrease the risk of miscarriage and improve the chances of pregnancy. Women with adequate progesterone levels according to the literature, would continue with the standard dose of progesterone prescribed at clinique ovo which is 300 mg (100 mg 3x/day). PIBF (Progesterone Induced Blocking Factor) levels, a protein found in the blood that could also predict pregnancy outcomes in women using IVF will also be looked at.

This RCT will test the effect of a 7-week self-help ACT-based program in improving fertility-related quality of life and psychological flexibility, in women with infertility.

GnRH antagonist protocol is currently a good strategy for controlled ovarian stimulation in women with PCOS undergoing IVF/ICSI cycles. Finding a protocol that can be a better alternative will help in improving the success rate of IVF/ICSI cycles

The goal of this randomized controlled trial is to compare letrozole alone versus letrozole plus levothyroxine for ovulation induction in infertile women with both PCOS and subclinical hypothyroidism. The main questions it aims to answer are: Is letrozole plus levothyroxine superior to letrozole alone in achieving ovulation in these patients? Does combining levothyroxine with letrozole lead to higher pregnancy and live birth rates compared to letrozole alone? Participants will be randomized into two groups: Group 1 will receive letrozole only, starting at 2.5 mg daily from day 3 to 7 of the menstrual cycle. The dose will be increased up to 7.5 mg if no ovulation occurs, for a maximum treatment period of 6 months or until pregnancy is achieved. Group 2 will receive letrozole at the same doses as group 1 plus 25 mcg levothyroxine daily.

This study is a single-center, randomized, controlled prospective study. Those patients with repeated implantation failure (RIF) who will recieve frozen thawed embryo transfer (FET) are enrolled in the study. To determine the effect of vaginal progesterone on the clinical pregnancy outcomes of RIF patients.

The goal of this single center, non-blinded, randomized controlled clinical trial to comparison of pregnancy outcomes and perinatal outcomes in patients undergoing IVF treatment (including ICSI) with FET with letrozole-induce endothelial preparation protocol versus natural cycles, hormone replacement protocol. The main questions it aims to answer are: To investigate whether letrozole-induce endothelial preparation is effective in improving the live birth rate and clinical pregnancy rate. To explore its possible impact on clinically important indicators such as spontaneous abortion rate, implantation cycle cancellation rate, days of endothelial preparation, and number of visits to the clinic. The study subjects were randomized into groups starting at D1-D3 of the menstrual cycle. The study subjects were stratified according to whether their menstrual cycles were regular or not, and were divided into the following endothelial preparation regimens according to the pre-prepared stratified zoned randomized group numbers: (1) regular menstrual cycles (25-35 d): letrozole ovulation-promoting cycles, natural cycles, and hormone-replacement cycles; and (2) irregular menstrual cycles (<25 d or >35 d): letrozole ovulation-promoting cycles, hormone-replacement cycle.

Poly cystic Ovarian Syndrome (PCOS) is an endocrine disorder of reproductive age defined by "the presence of any two out of three criteria: oligo and/or anovulation, excess androgen activity and/or polycystic ovarian morphology on ultrasound". Considering role of vitamin D (VD) (3, 4) and high prevalence (58%) of deficiency in PCOS of Pakistan. Researchers hypothesized that its correction would improve response to standard PCOS treatment. The objective is to compare PCOS parameters in intervention group (Group A) receiving VD supplementation and then PCOS care with control group (Group B) receiving standard PCOS care and then VD supplementation. A randomized open label trial: delayed-start design will be conducted on VD deficient PCOS females VD < 20ng/ml ; Group A will receive VD injections 600,000 I.U I/M once with 1 gram calcium supplement daily in the initial 12 weeks. After that standard PCOS care; i) Glucophage XR 750 mg (once for 15 days then twice daily) ii) progesterone supplementation (1 capsule Progeffik 100 mg every 3 weeks, then 1 week off) and iii) calcium supplements will be given for next 12 weeks. PCOS females in Group B will receive standard PCOS care (same) with addition of VD and calcium supplementation after 12 weeks till study end point. Study outcomes will be comparison of i) hyperandrogenism by Free Androgen Index [Total Testosterone, Steroid Hormone Binding Globulin ii) insulin Resistance by HOMA-IR (serum Insulin, Fasting Blood Glucose) and iii) oxidative stress by Total Antioxidant Capacity after 24-weeks in these Groups'd levels after supplementation will be assessed for confirmation of correction and calcium and albumin levels for detection of hypercalcemia. Results of this study will inform the clinicians to add VD before or after the standard PCOS care for rectification of endocrine and metabolic derangements as a cost-effective treatment and prevention strategy in these females.

The purpose of this study is to see if the investigators can obtain non-inferior clinical outcomes (similar numbers of oocytes) using the Cardinal protocol, a cost-conscious, low-intensity egg freezing protocol, compared to other routinely used high-intensity clinic protocols. This is a new program for Stanford's Fertility Clinic, so the investigators are assessing patient experience and cost-benefit of a low-cost, low-intensity approach that has demonstrated non-inferiority in IVF for infertility treatment, but has not been similarly evaluated in egg freezing. All enrolled participants will choose the Cardinal protocol or the routine high-intensity protocol designated by their physician. The investigators will then assess number of eggs retrieved, as well as patient satisfaction, cost, and time needed off work to complete the egg freezing cycle. The study's findings could ultimately open the door to implementation of lower-cost standardized protocols that would be more affordable and accessible to people who may otherwise not be able to pursue fertility preservation.

A non-pharmacological, non-blinded, randomized cohort study that will investigate the effect of Virtual Reality technology on the patient experience during oocyte retrieval. The primary objective of the trial is to investigate the impact of Virtual Reality technology on the patient experience

Infertility was reported in approximately 15% of all heterozygous couples, with male factor accounting for nearly half the cases. This typically occurs due to low sperm production, sperm dysfunction, and sperm delivery obstruction. Etiology of male infertility can be attributed to many factors including acute or chronic illness, accidents, and lifestyle choices.
