Brief Summary

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.

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.

Non-pregnant grouphuman chorionic gonadotropinA female is considered not pregnant when no explicit gestational sac is seen inside the uterus by ultrasound 4 weeks after embryo transfer.

Primary Outcome Measures
NameTimeMethod
Blood and follicular fluid vitamin D concentrationsImmediately after oocyte retrieval

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

Blood and follicular fluid vitamin E concentrationsImmediately after oocyte retrieval

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

Blood and follicular fluid zinc concentrationsImmediately after oocyte retrieval

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

Blood and follicular fluid glutathione peroxidase concentrationsImmediately after oocyte retrieval

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

Secondary Outcome Measures
NameTimeMethod
Biochemical Pregnancy Rate%2 weeks after embryo transfer

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

Embryo QualityDay of transfer (2 or 3 days after microinjection)

Embryos are assessed using Nikon SMZ1500 stereoscope

Maturation Rate%Within two hours after oocyte retrieval

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

Number of Metaphase II Oocytes (MII)Within two hours after oocyte retrieval

The oocyte maturity will be assessed using Nikon SMZ1500 stereoscope

Fertilization Rate%16-18 hours after microinjection

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

Clinical Pregnancy Rate% (Per Embryo Transfer)4 weeks after 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

Number of oocytes retrievedImmediately after oocyte retrieval

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