Brief Summary: Whether oestradiol administration affects the pregnancy rate in long agonist fresh IVF/ICSI cycles. Oestradiol level will be measured the day of HCG trigger to assess whether oestradiol level affects cycle outcome results.
Detailed Description: 6\. Background and Rationale: Progesterone is essential for successful implantation and maintenance of early pregnancy . Although the oestrogen is not essential, it is important to maintain the progesterone level during the pregnancy and promote the transformation of the endometrium from the secretory to proliferative phase.

Compromised granulosa cells luteinisation could cause infertility or early miscarriage. In assisted reproductive technologies (ART) cycles, curettage of the granulosa cells during oocyte retrieval is thought to reduce corpora lutea function and thus progesterone production, resulting in a decrease in pregnancy rate.

Therefore, luteal support is routinely performed in ART cycles. Consensus has been reached on the supplementation of progesterone after the day of oocyte retrieval, which was performed in approximately 80% of the cycles and significantly improved clinical outcomes.However, the efficacy of oestradiol supplementation in luteal support remains controversial.

Previous studies have shown that the lower the serum estrogen level was at 4, 7 and 9 days following transplantation, the lower the clinical pregnancy rate. Previous studies showed that in patients with long or short duration ovulation induction, luteal support with oestradiol supplementation led to an increased serum estrogen level and an improved pregnancy rate . It was also found that patients having luteal support with estrogen (4 mg per day) had a significantly higher clinical pregnancy rate (40.6% vs 21.6%) and a significantly lower abortion rate (12.8% vs 38%) than those treated with progesterone alone.

In contrast, other investigators have failed to show any benefit of oestradiol supplementation during the luteal phase and a Cochrane review published in 2015 reported no differences in rates of live birth or ongoing pregnancy between the progesterone group and progesterone add oestrogen group. Hence, it remains unclear whether the addition of estrogen to progesterone for luteal support is associated with higher pregnancy rate and live birth rate.

In this study, the investigators will evaluate outcomes of patients undergoing IVF/ICSI-ET with oestradiol supplementation in addition to progesterone for luteal support. The investigators also report on the efficacy implications of oestradiol supplementation for patients undergoing IVF/ICSI-ET.
