About this study

Official title: Vitamin D and Some Antioxidants and Trace Elements Levels in Women: Relationship With I.V.F Outcomes

observation of females condition will getting pregnant by undergoing assisted reproductive technologies, the most important of which is the in vitro fertilization (IVF), where blood and follicular fluid samples are collected from them at the same stage of in vitro fertilization, and then monitor the IVF outcomes until pregnancy occurs or not, based on blood tests. The levels of interested markers in blood and follicular fluid samples of the study individuals are assayed in order to compare these levels with the egg criteria such as egg number and maturation rate and finally compare the results with occurrence or absence of pregnancy.

Read the detailed description

Vitamin D, vitamin E, zinc and glutathione peroxidase will be measured in blood and follicular fluid samples of study subjects for women undergoing in vitro fertilization after monitoring their health for two to three months before beginning the first stage of in vitro fertilization. Once start the ovulation induction protocol, which is the first stage of in vitro fertilization, we will monitor all the results from the number of eggs and follicles, their diameter, the thickness of the endometrium, the number of mature eggs, the egg maturation rate and fertilization rate to the occurrence of biochemical pregnancy or not later, based on the blood Human chorionic gonadotropin (hCG) levels two weeks after the embryos transfer to the uterus. The patient is monitored until clinical pregnancy is complete or not. On the other hand, we will later compare the levels of studied parameters with the aforementioned egg quality criteria and with the clinical pregnancy rate of the study group in order to understand the relationship between these studied parameters and the occurrence of pregnancy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • human chorionic gonadotropinDrug

    Also called Chorex

    10000 IU when at least three follicles become more than 16 mm

Study groups in NCT05393011
Study groupRoleWhat they receive
Pregnant groupA female is considered pregnant when an explicit gestational sac inside the uterus is seen by ultrasound 4 weeks after embryo transfer.
Receives: Drug: human chorionic gonadotropin
Non-pregnant groupA female is considered not pregnant when no explicit gestational sac is seen inside the uterus by ultrasound 4 weeks after embryo transfer.
Receives: Drug: human chorionic gonadotropin

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Blood and follicular fluid vitamin D concentrations

    Blood and Follicular fluid samples will be obtained on the day of oocyte retrieval, then they will be centrifuged to eliminate cellular elements and debris. After that, the supernatants will be frozen at -80 until later assayed

    Measured: Immediately after oocyte retrieval

  2. Blood and follicular fluid vitamin E concentrations

    Blood and Follicular fluid samples will be obtained on the day of oocyte retrieval, then they will be centrifuged to eliminate cellular elements and debris. After that, the supernatants will be frozen at -80 until later assayed

    Measured: Immediately after oocyte retrieval

  3. Blood and follicular fluid zinc concentrations

    Blood and Follicular fluid samples will be obtained on the day of oocyte retrieval, then they will be centrifuged to eliminate cellular elements and debris. After that, the supernatants will be frozen at -80 until later assayed

    Measured: Immediately after oocyte retrieval

  4. Blood and follicular fluid glutathione peroxidase concentrations

    Blood and Follicular fluid samples will be obtained on the day of oocyte retrieval, then they will be centrifuged to eliminate cellular elements and debris. After that, the supernatants will be frozen at -80 until later assayed

    Measured: Immediately after oocyte retrieval

Secondary outcomes (7)
  1. Number of oocytes retrieved

    The oocytes will be retrieved by transvaginal ultrasound-guided follicle aspiration after ovulation trigger

    Measured: Immediately after oocyte retrieval

  2. Number of Metaphase II Oocytes (MII)

    The oocyte maturity will be assessed using Nikon SMZ1500 stereoscope

    Measured: Within two hours after oocyte retrieval

  3. Maturation Rate%

    Maturation Rate is calculated by dividing the number of mature (MII) oocytes by the number of retrieved oocytes

    Measured: Within two hours after oocyte retrieval

  4. Fertilization Rate%

    Fertilization Rate is calculated by dividing the number of obtained zygote (2PN) by the number of injected oocytes

    Measured: 16-18 hours after microinjection

  5. Embryo Quality

    Embryos are assessed using Nikon SMZ1500 stereoscope

    Measured: Day of transfer (2 or 3 days after microinjection)

  6. Biochemical Pregnancy Rate%

    Biochemical pregnancy is defined as a positive serum beta-hCG pregnancy test after 2 weeks of embryo transfer. The biochemical pregnancy rate is calculated by dividing the number of women who are biochemically pregnant by the number of women who have at least 1 embryo transferred

    Measured: 2 weeks after embryo transfer

  7. Clinical Pregnancy Rate% (Per Embryo Transfer)

    weeks of embryo transfer. The clinical pregnancy rate is calculated as by dividing the number of women who are clinically pregnant divided by the number of women who have at least 1 embryo transferred

    Measured: 4 weeks after embryo transfer
